What I'm looking for

I seek roles where I can lead small teams, own end-to-end product areas, stabilize systems, and deliver reliable real-time features in a collaborative, process-driven environment.

I am a Senior Full-Stack Developer and Team Lead with 4+ years of experience stabilizing early-stage and production systems, rebuilding payment flows, and delivering business-critical functionality end-to-end. I specialize in React and real-time data visualization on the frontend, with backend expertise in Python (Django, Celery), Node.js, and .NET, and hands-on experience implementing infrastructure, CI/CD, and operational processes.

I have led small distributed teams, introduced structured engineering practices, and improved system reliability and performance—most notably redesigning a production payment system with a ~1000x payout performance improvement and reducing client-reported issues by ~70%. I prioritize predictable delivery, cross-team coordination, and pragmatic technical decisions that align engineering work with business needs.
