I'm a senior React and TypeScript engineer with 5 years of commercial experience. I get up to speed fast and become a real part of the team from day one. Most of my work has been on products that already exist: at Yandex I migrated several projects to a new build setup, cutting the bundle by 30% and speeding up builds 5 times, and led a portal redesign for 19,000 monthly users without breaking what was already live. The React to Next.js migration is what got me interested here. I'd like to hear what hurts most in the current codebase before you move further off it, and where I can help most. Let's talk.…I'm a senior React and TypeScript engineer with 5 years of commercial experience. I get up to speed fast and become a real part of the team from day one.
