Michał Lach

I’m a Senior Frontend Engineer with 10+ years of experience designing and delivering scalable web and mobile applications across fintech, AI, enterprise, healthcare, and media. I focus on modern frontend architecture, component systems, and performance optimization, while keeping developer experience and maintainability at the center of how I ship. Most recently at Nordea, I’ve developed internal enterprise platforms to streamline API onboarding and shared services, built secure access-management workflows for internal AI solutions, and contributed to Redis management tooling that improves operational workflows. Previously, at MasterBorn, I led frontend delivery of a transaction gateway, designing scalable React + TypeScript architecture and improving maintainability and developer productivity through reusable components and modern tooling—alongside close collaboration with product, backend, and design teams in agile environments.
