About me

Senior Full Stack Developer with 12+ years of commercial experience. I build and improve web and desktop applications, fix bugs and integrate APIs and AI features. Stack: TypeScript, React, Next.js, Angular, Node.js, NestJS, PostgreSQL and MongoDB.

LEOLEX AI: built most of a commercial legal-tech app, including NestJS services, React/Electron interfaces, OpenAI/LangChain.js document analysis and cloud-drive OAuth integrations. Deviniti: led delivery of AI apps for Atlassian Marketplace in a small team; one app placed third in CodeGeist. CargoNest: transport-document processing and integrations. Currently: full-stack development for Infogian / FedEx.

I help clarify requirements, define a practical scope and deliver working software. We can start with a small paid milestone: a bug fix, integration or scoped feature. Available remotely up to 40 hours per week. Polish native; English B2. Invoicing through my own business.
