At Poly9, I build and ship full-stack product features using Next.js, TypeScript, and Node.js, from system design through deployment. I also integrate AI- and LLM-powered workflows into the product.
At Propelius Technologies, I led development and maintenance of web applications with React, Next.js, and TypeScript. I worked with PostgreSQL, Supabase, and MongoDB, and integrated Firebase for real-time data.
On my POS retail fintech project, I built payment processing with multi-channel transaction management and automated bookkeeping. I designed an offline-first sync system that reached zero transaction loss and 99.9% data consistency during network outages.
As a Research Development Intern at Vrije Universiteit Brussel, I built a blockchain-based decentralized research publishing system. It used MetaMask authentication, IPFS manuscript storage, and Ethereum-based reviewer–author anonymity.
