What I'm looking for

I am seeking senior backend/cloud roles where I can design scalable, cloud-native microservices, mentor teams, and deliver reliable, performant systems.

I am a senior software engineer with deep expertise in backend development, distributed systems, and microservices architecture. I build scalable, cloud-native applications using Python, Go, and modern frameworks.

Throughout my career I have engineered REST and GraphQL APIs, integrated ML models for real-time inference, and migrated legacy systems to Kubernetes-based deployments. I emphasize test coverage, reliability, and performance with tools like PyTest, Locust, Prometheus, and Grafana.

I have led mentoring and technical workshops, guided junior engineers, and conducted rigorous code and security reviews to promote best practices and maintainable architecture. I also collaborate with design teams to build reusable React component libraries and improve frontend consistency.

I seek to deliver pragmatic automation and observability, drive cost-effective cloud solutions with AWS and GCP, and design event-driven, highly available systems that accelerate business outcomes.
