Side Projects Q&A and Videos

What's the best way to upskill oneself in emerging fields?

for example, what would be the most effective and easiest way of upskilling in Data & AI projects in absence of any direct work opportunities that involve those fields?

I'd like to ask for your feedback on my side project - a full-stack simulation of a ride-hailing app such as Uber or Lyft.

App: 
Blog: 

A bit of background first. I've been wanting to publish a personal full-stack project for a while. These were my main reasons:

• I wanted a platform to explore concepts and tools I don't get to work with in my day job, helping me accelerate my learning.
• I've wanted to break into big tech and thought this project could help me stand out among many applicants.
• I enjoy writing and wanted to get better at it.

Why did I choose a simulation of the Uber/Lyft app? I always found something very attractive about these apps - they're visually appealing and dynamic, with colossal architectures behind them. I thought it would be very cool to re-implement some aspects of such an app. I have also been reading the Uber engineering blog and got a glimpse of the complexity these companies are dealing with.

My final goal with this app was to have an animated map with cars picking up customers, driving them across the map and dropping them off at their destinations. Customers would post ride requests and the system would match them with the nearest drivers. The simulation would run on the backend, and the frontend map would show the action in real-time.

I started working on the project last autumn. I've spent around 300 hours working on it and you can see the result in the links above.

My ask

I'd love to get your feedback to improve or extend this app and my blog, keeping in mind my objectives:

• I plan to apply to big tech companies this summer, and I'd like this project to help me with my applications.
• The project targets both recruiters and hiring managers. With recruiters, the goal is to pass the initial screening and get me to the interview stage (of course, I'll also be trying to secure referrals, but I might not always succeed). With hiring managers, this project might help me score extra points in my final evaluation.
• I might be applying to companies such as Uber or Bolt, but this project is not supposed to impress just the ride-hailing companies.
• I prefer not to put much more time into the project at the moment, as my focus right now has to be on the coding interview prep.

Possible additions or improvements include:

• Splitting the system across multiple machines (perhaps 3), making it truly distributed.
• Adding various components used in large-scale systems such as load-balancer, rate limiter, or message queues. Indeed, these components are not actually needed for the app to function. But by doing so, I could demonstrate my ability to work with them (albeit not necessarily demonstrating deep expertise).
• Adding comprehensive documentation with system diagrams and explaining the choices I made.
• More rigorous testing by adding integration tests (right now, I only have unit tests).

As for my previous background - I've been an engineer for ~4.5 years, most of my experience is from a small startup (series B). I consider myself a full-stack engineer but going forward, I aim to specialize more in the backend. Therefore, the project should strongly communicate my backend skills. For my next role, I also prefer backend positions to full-stack ones.

Recently I watched the great masterclass from Rahul and Alex on side projects. It made me realize that while my project might be interesting from a technical perspective, it has no users. In fact, this app doesn't allow any user interaction by nature. However, what I'm lacking in terms of users, I'm hoping to make up with the degree of technical complexity. Please also share your views on this aspect.

Many thanks if you've read this long post to the end. I'll be very grateful for any tips on how to make this project more appealing 🙏🏼

What’s the best way to learn really good front end engineering? Specifically what frameworks / languages are useful, design patterns, and some projects to get hands dirty?

my motivation for learning front end is to build products that people would actually use :)

Hi all,

I recently finished the Masterclasses from Alex & Rahul where Alex & Rahul discussed building apps as side projects to put on resumes. Also in , Alex mentioned he monetized his app & got $100 from premium users.

AFAIK, anything above $400 must be put onto tax return. I'm thinking about developing a small side projects & put maybe ads / premium restrictions on some features. If I do this, how do I avoid conflicts of interest with my 9-5 job, especially if the revenue coming in may way surpass $400? I'm working for a large tech company that essentially do everything hence it's hard to find a business area where the company isn't involved in.

I am a frontend focused full-stack engineer with 7 years of relevant experience in the frontend engineering space and a total of 12 years of experience. I am not able to decide where should I invest my time when working on side projects. Should I start picking up mobile (Android/iOS) or continue to sharpen my skills in the frontend development space? To put it another way, should I invest my time in going deep in my current domain or should I invest time learning mobile UI development as that has gained more traction and is viewed as more valuable skill?

I think I am unable to decide whether to go about developing my skills in breadth or depth.

Hello,

I am a conventional engineer (mix of startup experience + service industry).

I am thinking of starting a product company but had a few questions.

I think I am comfortable from a technical standpoint and no dearth of ideas.

But my questions are more centered around funding. I have not made a similar effort before and almost all of my experience is mostly technical and not managerial.

For such a scenario, do you think the best best is to be able to garner a large amount of users?

I am working on a cool side project (full stack web app) which can genuinely be used and is quite helpful based on feedback I've gotten from friends who have used a prototype version. I want to actually get it out to a user base, and had a few questions:

1. How and where do I host it to keep the costs down?
I've built the backend REST API in Golang and Gin, and it uses a postgres DB to store the data. The frontend I have not started but, it will be built with React with Vite. I'm not sure what the best cost effective way of hosting it is, especially since I am planning on making this app free to use (or perhaps it is time to find a way to monetise it to cover costs). It was originally on AWS but the monthly fees were too much and I had to take it down.

(also note that I am only an intern / grad level engineer, with most of my experience in frontend, so my infrastructure knowledge is very limited)

2. How do I promote it and let people know about it?
How do I market it for free, and let people know about it and try to use it? I have some knowledge in SEO, but that is about it. Social media, Reddit and things like that come to mind, but I don't have a following on anything.

The goal is to build something genuinely helpful for people while having something cool to show off to potential employers, while not costing much money as I have no income right now.

Thank you!!

I'm ambivalent about attending Taro Networking events. On the one hand, the people I meet there are so talented and nice! On the other hand, what am I really getting by meeting them?

Now, I know I just said something extremely transactional. That I don't seem to "get" anything from meeting people. But let's continue this line of thinking for a bit. In my mind, going to a networking event can get you 3 things:

1. potential job referrals

2. potential partners for side-projects and maybe even a startup (which can be considered a kind of job referral)

3. friends/social-contact

Let's assume that I'm not looking for friends, so only the first 2 are in play.

What should I be doing while networking? What happens is I tell them about what I do - my role, company, stack - they do the same, we'll talk about the industry for a bit, and that's that. It seems to me like I'm not getting much out of it, probably because I'm doing it all wrong.

Here's an excerpt from an email from a Data influencer I follow who makes a similar point:

Traditional networking is like a relic of the past for back when we didn't rely on the internet.

Back then, people only recommended and worked with those they'd met in person.

But in our digital age?

We can instantly find and judge coders, designers, data experts, and marketers online based on their LinkedIn & portfolio sites. 

So, here's an alternative to traditional networking... 

**Build things that matter. 

For example, let's say you wanted to break into genAI, or land an e-commerce job at Amazon, or work in ad-tech at Facebook or Google.

To impress hiring managers and recruiters at these FAANG companies, you could build an AI tool for to help retailers advertise more efficiently.

So his point is to build stuff and use that as the fodder for networking. I'm inclined to agree, since personally, my side-project cupboard is bare. I could be falling into the trap of thinking that I can/should only network once I've reached a threshold of building however.

So to sum this up, how do you balance networking vs. building and can you expand on the relationship between them?

Thanks!

Hello, I asked about this before, but it’s a bigger dilemma now as I’m actively interviewing and many top roles seek a software engineering background.

Scenario: This past year at an AWS Cloud Consulting Partner, I built cloud and Terraform skills but had little software engineering experience. I dabbled in a few languages but haven’t committed to one. I want a versatile, productive, “startupy” language for an ambitious one-man project (possibly a PWA) that fuels learning, supports entrepreneurial goals, and offers a great dev experience.

What I Enjoy: I love game dev with Godot, but GDscript has no job market. So, I’m considering a scalable full-stack CRUD project like a PWA game site (think ) that I can build solo. I want to master one language and framework — no constant framework-hopping like with JavaScript. Here are my main options:

1. Ruby on Rails – Productive, “batteries included,” and fun (so I hear). While some call it “dead,” remote roles (like GitLab) still exist. I worry about it being a risky specialization.

2. Blazor + .NET Core – Full-stack with one language (C#) and “batteries included” features. Blazor is new, but .NET Core skills stay relevant. I dislike JavaScript’s endless framework churn, so Blazor’s stability is appealing.

3. Golang – I like its “one way to do things” philosophy, compiled binaries, and cloud reputation. But it’s focused on microservices, not full-stack projects. I’m unsure if I’d stay motivated building APIs instead of an end-to-end product. Python feels similar — powerful but maybe not a “do it all” full-stack option.

The Goal: I need speed, productivity, and specialization in a language worth mastering. I want to build a PWA project that teaches me core software skills fast and makes me marketable for software engineering roles.

What would you recommend?

I've been in the IT industry for 3 years, working on various projects. For the past 1.5 years, I've been heavily involved in Python projects, mainly as a back-end developer using Django. My tasks typically revolved around building or updating APIs as per specific requirements.

Most of these projects were already underway when I joined, so I mostly inherited tasks based on existing project needs. As a result, I wasn't part of the initial database design or project structuring.

Now, I'm starting on my personal project using Django. However, I lack experience in structuring and designing a project from scratch, especially in organizing apps and defining models.

I took a look at other frameworks like Spring Boot and noticed they don't offer the same level of "batteries included" features as Django.

I'm currently dealing with two main challenges:

1. Impact of Learning Django First: I'm concerned that focusing solely on Django might limit my overall understanding of back-end development. Django's comprehensive built-in features might not be present in other frameworks, and that worries me.
2. Project Design and Structure: I'm puzzled about the best practices for structuring and designing a Django project, especially regarding app organization and model structuring.

I'm seeking advice on overcoming these issues and figuring out how to structure my project effectively. I'm also contemplating whether sticking with Django could potentially narrow my overall grasp of back-end development because of its extensive in-built functionalities.

Also, I applied to some companies and most of them are asking for experience in Java back-end development.

Working on personal projects is fun. You have ownership, you work on a problem you care about, etc.

But at work, you might not care too much about the problem that the company product is solving, or you might not have sufficient ownership, or maybe your role is too restricted (e.g., you like talking to customers, but the nature of your SWE job means you are only expected to code).

Basically, you know what you like, but the nature of your job does not fully align with your desires/goals.

How do you navigate such situations?

Many people say to have a hobby outside of work so that you don’t crave fulfillment from work itself. That could be an approach, but I feel that when the work itself is fulfilling/fun/in alignment with what we want, that could be an even better way, as it’s tied to career growth.

Hi Taro Community!

I am in a very similar position as mentioned by someone here: and from the responses it is evident that switching teams/companies will be an unavoidable step soon. I am currently at an entry-level position (will be completing 6 months at current company soon) and wish to look for roles at the next level of hierarchy (for instance my current role is equivalent to SDE 1, I wish to look for roles similar to SDE 2 or equivalent next). Few points:

• I am planning to complete 1 year at my current company, so by the time I switch I shall have ~1 yr of experience as an entry-level software engineer (apart from other experiences as internships/side projects/etc.)
• Firstly, is it realistic to prepare for mid-level at the current position? Do companies hire entry-level SWE's with at most 1 yr of experience for mid-level?
• If yes, is it advisable to apply now (or 6 months down the line)? I do not wish to work as an SDE-1 (entry-level) in another company by leaving my current one as it will only lead to further delays in promotions (I believe it takes at least a few months to set a good impression in a new team that you are capable for a promotion)
• How can I best utilize the next 6 months before I aggressively start applying to companies? I understood the point related to side projects - is it advisable to build side projects in the tech stack my team is using, or should I expand my scope to include new technologies I am interested (but not actively working on right now)?

Any insights/suggestions/interview tips will be really appreciated. I have very less workload right now and really want to make the best use of time to switch further.

Thank you!

Git/version control is an important skill for people in tech. What are some ways to get good at it? It's often easy to do things in a hacky way when there is a git command that does exactly what you want to do that will save you a lot of time in the long run. Also, understanding the fundamentals of how Git works can go a long way.

What are some good tips? Other than , of course :)
