Summary
👤
Senior🎓
Top SchoolŁukasz Jagodziński is a Full Stack Developer with over a decade of professional experience and a lifelong passion for coding that began at age 10. He has driven architecture, performance tuning, and developer-experience improvements across startups and product teams (Intellipse, Konvo AI, Mutiny, Duolingo, and now Playlab AI), often balancing code quality with pragmatic business trade-offs. Skilled across TypeScript/JavaScript, React, GraphQL, PostgreSQL, and modern infra like Kafka and Redis, he repeatedly tackles tough performance problems—from query optimization to rethinking module architecture. He enjoys early-stage roles where he can shape tech stack and best practices, and he’s particularly drawn to developer tooling and AI-enabled products. A practical perfectionist, he contributes beyond code—mentoring, interviewing, and migrating systems to monorepos to streamline developer workflows.
