Message

At Andersen Lab, I led frontend development of a large-scale CRM platform, delivering five core modules, and raised test coverage from 65% to 90% using Jest and React Testing Library. I also enhanced an online banking platform with microfrontend architecture and contributed more than 30 reusable components to a private UI library.

At Todes, I integrated Tanstack Query for pagination and applied Next.js optimization strategies, including server-side rendering and static generation, improving application performance by 2.5x. Earlier, I worked on React Native and React applications at ScienceSoft and Tapston, including real-time communication features, location tools, and a websocket chat system.
