What I'm looking for

I seek senior engineering roles where I can build scalable, cloud-native platforms, lead technical migrations, mentor teams, and deliver measurable product and performance improvements.

I am a Senior Software Engineer with 13+ years building scalable, production-grade web platforms using Node.js, TypeScript, React/Angular, and cloud services (AWS/GCP). I design APIs and architectures that handle millions of monthly transactions and support tens of thousands of concurrent users.

I have led migrations from monoliths to event-driven microservices, integrated third-party APIs, and implemented CI/CD and infrastructure-as-code to accelerate releases and improve reliability. My work has measurably reduced latency, defects, and support escalations while increasing user adoption and revenue.

I mentor engineers and author technical documentation, run books, and onboarding guides to shorten ramp time and improve team consistency. I have hands-on experience with real-time systems (Socket.IO), search/analytics, and document automation enhanced by AI integrations.

I hold cloud and platform certifications and seek to contribute pragmatic architecture, strong API design, and team leadership to mission-focused engineering organizations aiming to scale reliably.
