About me
I am a Senior Frontend Developer with 7+ years of experience building product-focused web applications with React and TypeScript. I currently work in FinTech, where I lead a small frontend team developing investment products and improving architecture, delivery workflows, and product quality.
My main interests are modular frontend architecture, GraphQL, performance, testing, browser internals, and turning changing product requirements into maintainable systems. I also build independent tools, including Applied Vacancies Tracker, and contribute to open-source projects when I can.
