What I'm looking for

I seek remote-friendly roles building resilient, secure distributed backend/platform systems where I can lead migrations, mentor engineers, and deliver high-availability services.

I am a backend and platform-focused software engineer with experience designing scalable payment processing systems, architecting microservices, and driving migrations that reduced vulnerabilities and improved performance. At a major telecom & fintech company I led Java migrations, database migrations, and built cross-market configuration APIs, contributing measurable revenue and high availability for users.

I mentor junior engineers, promote engineering best practices, and have full-stack and embedded systems experience from prior roles building end-to-end features and IoT devices. I seek roles where I can continue building resilient, secure distributed systems and lead technical improvements across teams.
