What I'm looking for

I seek senior engineering roles where I can architect scalable systems, lead technical initiatives, drive CI/CD and observability improvements, and work on AI-driven features in a collaborative, growth-oriented team.

I am a Senior Software Engineer with 9+ years of experience building scalable backend and frontend systems, deploying large-scale services on AWS and GCP, and leading cross-functional teams to deliver high-impact features.

I have architected microservices migrations, developed AI-driven search and personalization using Python and ElasticSearch, and implemented high-throughput C# and Java services backed by Kafka and PostgreSQL to meet strict latency and availability goals.

I am passionate about improving developer productivity and reliability through CI/CD automation, observability (Datadog, Prometheus, OpenTelemetry), and strong engineering practices that reduce technical debt and accelerate delivery.
