Back—Dev.
Backend engineer specialized in financial systems. For 6 years I've built payment APIs and infrastructure in production — with Python, Go, and cloud. I work where consistency and reliability aren't optional.

Backend where mistakes cost money.
I've spent the last years in fintechs and payment systems — Zapay, CondoConta — building the backend that actually moves money. That context shapes how I work: idempotency, reconciliation, and traceability aren't features, they're requirements.
Python is my foundation; Go when I need concurrency and performance. I work from system design to production delivery — and when the front needs it, I go Full Stack with Vue and React. What interests me isn't the language, it's the system: bottlenecks, consistency trade-offs, infra cost.
These days I bring AI agents, MCP, and automation into the engineering workflow itself — a working tool, not a buzzword.
