Congratulations on breaking into tech and becoming a junior engineer! Now how do we make it so people stop calling you "junior" as soon as possible? 😅

Well, you do that by growing from a junior engineer to a mid-level engineer. The good news is that if you are on a decent team, your destiny is completely in your hands when it comes to this promotion. When you play your cards right, you will make this level up fast. By the end of the course, you will:

  • 💡 Truly understand the difference between a junior engineer and a mid-level engineer

  • 🛠️ Learn to code like a mid-level engineer

  • 💪 Know what it means to be truly independent

  • 🧠 Have the right mindset to act as a mid-level

  • ✅ Define a clear roadmap to mid-level

Being a junior engineer is scary - You don't know what to do, and the job market is the harshest towards you. But worry not: After going through all the lessons in this course, you will have the necessary tools to quickly grow from a clueless junior engineer to a fearless, respected, and extremely capable member of your team!

Meet Alex Chiou

Alex Chiou is a proven Silicon Valley engineer with 10+ years of experience across top tech companies like PayPal, Course Hero (now Learneo, a $3.6B unicorn), Meta, and Robinhood.

He became a tech lead just a couple years into his career by owning the entire Course Hero Android app (100k+ users) as their 1st Android engineer. After that, he expanded his scope as a tech lead at Meta and Robinhood, shipping multiple $10 million+ revenue projects with 15+ engineer teams.

Leapfrogging Junior

Alex became a mid-level engineer just 1 year into his career, joining Course Hero as their 1st Android engineer and lead to build their Android app completely from scratch.

He did this by sharpening his coding skills (a lot of which was done outside of work), being a feedback sponge, and heavily working on his communication overall. Despite being a big introvert and falling behind in college, Alex was able to quickly overcome barriers to grow past junior.

The Master Of Cultivating Junior Talent

Alex loves mentoring engineers, directly growing 50+ of them to lightning fast promotions at top companies like Meta and Robinhood. His favorite mentees were the ones he got to raise all the way from new-grad. His results speak for themselves:

  • Got 10+ Meta junior engineers [E3] promoted to mid-level engineers [E4] in just 1 year (2x faster than industry average)
  • Got 2 Meta junior engineers [E3] promoted to mid-level engineers [E4] in just 6 months (4x faster than industry average)

Junior isn't a title you should have for very long. With Alex's wisdom, you can make that your reality.

This is a great course! Alex is very good at expressing his thoughts. Even though I joined Amazon as an SDE II, I still learned a lot of insightful information from the course.
