Top SchoolMarcin Maślanka is a Senior Frontend Engineer with 10 years of experience building performant React and TypeScript applications and bridging complex backend systems to intuitive user experiences. Lately he’s focused on AI-native full-stack products, architecting multi-provider text-generation platforms (GPT-4o, Claude, Gemini) with streaming, search integration, and hierarchical controls at Common. He independently designed and shipped an end-to-end RAG pipeline and political matchmaking app, Fotelik, combining LLMs, Firecrawl and vector databases. Comfortable across frontend, backend and DevOps (Node.js, AWS, Docker, CI/CD), he brings production-grade pragmatism to AI feature engineering and semantic search. Based in Warsaw, he balances deep technical execution with a history of full-stack roles and a curious, practical approach to new AI tooling.
