What I'm looking for

I’m looking for an opportunity to contribute to meaningful products, collaborate with strong teams, and keep growing as a front-end/mobile developer.

At SELLEO EdTech & HRTech Software Development, I work across frontend and backend on an internal platform, delivering features with React and TypeScript alongside Rails services and Node.js/NestJS APIs. My work includes dashboards, reporting, data visualization, and document generation.

Previously at SELLEO, I contributed to a long-term production social and events platform for a US client across React Native mobile apps and React/Next.js web apps. I delivered features end-to-end, including events, groups, chat, maps, and registration flows, and worked on ongoing improvements to stability, performance, and user experience.

Earlier, I contributed to a React-based food delivery e-commerce platform at Aexol and taught programming at Giganci Programowania. I’m currently open to opportunities where I can contribute to meaningful products, collaborate with strong teams, and keep growing as a front-end/mobile developer.
