Summary
👤
Senior🎓
Top SchoolMichał Bar is a Frontend Software Engineer with eight years of experience building performant, user-focused web and native applications from Krakow. He specializes in TypeScript, Next.js, React Native and monorepo architectures (Turborepo), and has driven projects across healthcare, education and IoT where accessibility, SEO and reliability mattered. Michał frequently applies state machines (XState) to tame complex user flows and leverages @tanstack/react-query, Playwright and Jest to deliver resilient, well-tested experiences. He has implemented production-grade services like PDF rendering on serverless Chrome, email microservices with AWS SES, and MFA-capable authentication using NextAuth.js. Comfortable bridging web and native codebases, he often extracts shared business logic and hooks to maximize reuse and maintainability. Outside typical frontend work, he combines a formal CS background from AGH with practical mobile web training, giving him a rare mix of academic rigor and hands-on product engineering.
