What I'm looking for

I seek roles building scalable, secure, low-latency backend systems—preferably remote or hybrid—where I can lead architecture, mentor engineers, and drive product reliability.

I am a Senior Backend Engineer with deep expertise in Node.js, TypeScript, Go, and Python, focused on building low-latency, high-availability microservices for fintech and crypto platforms.

I have designed real-time trading APIs, WebSocket-driven platforms, multi-chain wallet systems, and secure backend infrastructure, achieving measurable performance and reliability improvements such as 40% reduced API response times and 99.98% reconciliation accuracy.

I thrive in fast-paced remote teams and lead technical direction, mentoring engineers while delivering end-to-end solutions from architecture through deployment and maintenance.
