About

Olga here :) a Software Engineer with 4 years of professional experience, focused on building user-centered, production-grade frontend applications with React and TypeScript. I started my journey in tech in 2018, learning JavaScript and building small demos, and began my professional career in 2021, working on real-world products used by people every day. Since then, I’ve focused on turning complex problems into simple, intuitive interfaces, with a strong emphasis on UI architecture, performance, and reliability. Over the years, I’ve worked closely with designers, backend engineers, and product teams, contributing to everything from early product ideas to fully shipped features. I enjoy collaborating, learning from others, and building software that feels good to use and easy to maintain. What motivates me most is creating products that actually help users, while continuously improving my engineering craft through better tooling, testing, and thoughtful design.
