Marcin Bis is a senior fullstack and mobile developer based in Warsaw with eight years of professional experience delivering React, React Native and TypeScript applications. He prefers designing and building clean, object-oriented systems using patterns and domain-driven design, and avoids roles tied to large technical debt. Recent work includes fullstack TypeScript on a React app for the Telegram Gaming Platform and senior React Native development across multiple consumer apps, demonstrating strong front-to-back integration skills with Firebase, GraphQL and CI/CD pipelines. He pairs pragmatic front-end UX improvements with backend performance and scalability work, and has hands-on experience with testing automation (Cypress, Jest) and deployment workflows (Bitrise, GitHub Actions). Comfortable as a fullstack developer, he brings a disciplined engineering mindset that favors long-lived, maintainable architectures over quick fixes. An understated strength is his consistent focus on reducing architectural debt while shipping user-facing features.
