About me

I build reliable software for systems where details matter.

I’m Eduardo Zborowski, a full-stack software engineer based in Vila Velha, Espírito Santo, Brazil. I have more than four years of professional experience, including three and a half years building financial technology, ATM systems, payment flows, and transactional applications.

My work spans React and TypeScript interfaces, Node.js and Java services, REST and WebSocket integrations, asynchronous events, databases, CI/CD, and production support. I care about precise state, observable behavior, defensive boundaries, and software that remains understandable when the happy path breaks.
