Career Advice About Mercari

I'm trying to figure out how to have a better disconnect between work and outside of work. Sometimes I'll get carried away on a task and I'll work pretty late on it, which negatively affects my sleep schedule. It’s all been kind of blurred, I can’t even remember when I stopped working sometimes. I'm also working with people in different time zones, so I'll work later than the traditional 9 to 5.

Overall, it's not too bad though. I'm mostly not working weekends, and this is mainly a thing on me: I don't have external pressure/crazy deadlines to overwork.

I’m okay at planning out short-term projects, but I have trouble with longer time horizons. As a new engineer here at Mercari, I'm currently working on a 90 day plan and I've been thinking about how to estimate projects. I want to figure out timelines in particular, so I can properly manage expectations. A lot of the time, I’m over-optimistic about what I can achieve, so I want to build a better muscle there.

For reference, I consider <1 month to be short-term and 2+ months to be long-term.

Should I be focusing initially on quick wins or higher-impact, high-priority projects that could potentially take longer?

I'm a new engineer at Mercari, and I want to make a big impact. So in terms of OKRs and the overall team roadmap, how do you think about how you can integrate that into your work as an engineer? More specifically, I want to influence the team's product direction instead of only doing the work that I'm given. Do you just need to have a good product sense in order to work in this style?
