What I'm looking for

I seek senior backend/platform roles where I can design resilient, scalable cloud-native systems, mentor teams, and drive platform modernization with strong observability and secure-by-design practices.

I am a senior backend software engineer with over 20 years building and modernizing high-volume transactional distributed systems. I focus on designing resilient, cloud-native platforms that meet strict SLA/SLO targets and scale to millions of daily transactions.

My hands-on expertise includes Node.js, TypeScript, Go, Kubernetes, AWS, PostgreSQL, Redis, Temporal, and CI/CD automation, and I routinely apply resilience patterns, observability, and secure-by-design practices to production systems.

I have led and mentored cross-functional engineering teams of up to 36 engineers, driving platform modernization from monoliths to microservices, improving reliability, delivery velocity, and operational safety across payments, retail, and high-demand event systems.

I integrate AI-assisted development tools into engineering workflows to accelerate code review, test generation, documentation, and architecture exploration while ensuring all outputs are validated with production-grade engineering judgment.
