I always liked to work with numbers and some sort of formulas. I had to develop the engine for frontend part of out system that calculated amount of money to charge based on variety of factors (discounts, amount of bonuses, gift cards and a lot of other) and products/services applied. It's actually related to the project that aims to automate processes at the network of beauty salons. Also I devised a plan to make code that looks the same on frontend (typescript) and backend (java) parts to make debugging easier in case of some miscalculations + same tests on both sides. Based on the information I have it has been used without any changes or issues since I left that project, so seems to be I did a good job.
I worked on a variety of projects throughout my career: news aggregator system, app to detect emotions and advice actions to improve it, abnormal speech recognition system, system that automates processes in a network of beauty salons. First I started as MEAN stack developer and then switched to MERN stack. My position was a full stack developer. Also I had a chance to work as a qa automation engineer. As for my preferences I prefer backend over frontend.
Probably I want to work on a product (or a startup on a later stage) with a lot of guys onboard, 'cause I've been working on startups throughout my career and want to try something new and have an opportunity to learn from more mature developers.

In terms of technical details I cannot say that I hate doing something, but I do not really like working with HTML & CSS. Personally I always liked backend development, but back in the time there was no such positions, 'cause everyone was interested in full stack devs, so had to keep up with frontend as well. I would really like to be proficient at both backend and devops, but it seems to be really hard to achieve if not possible together with frontend. There is not enough hours in the day for learning(( However If I had to focus on frontend part it would be nice as well.
