Hi,I’m a React Native and Full Stack JavaScript developer with 5+ years of experience building production-ready web and mobile applications.I specialize in React Native (Expo & CLI), React, and Node.js (Express), and I’ve worked extensively with modern tools such as TypeScript, React Query, Zustand/Redux, and REST APIs. I also have hands-on experience with databases like MongoDB, PostgreSQL, and Prisma, as well as integrating third-party services and APIs.In my recent work, I’ve been focused on building scalable mobile applications, improving performance, and delivering clean, maintainable code. I’m comfortable working in fast-paced environments, taking ownership of features, and collaborating with remote teams.I’m particularly interested in working on modern products where I can contribute both on the mobile and backend side, while continuously improving development speed and quality using modern tools (including AI-assisted workflows).I’d be happy to join a call or complete a test task if needed.You can reach me at: +38 067 756 9265 antoniakstepan1@gmail.com LinkedIn: https://www.linkedin.com/in/stepan-antoniak-274969196Looking forward to hearing from you.
