What I'm looking for

I seek backend or platform roles where I can build scalable distributed systems, improve observability, reduce costs, and mentor engineers in an impact-driven, collaborative team.

I am a backend engineer with three years of experience designing and operating high-scale Kafka pipelines, microservices, and observability platforms at Amazon and AdPushup. I focus on reliable, cost-efficient systems—containerizing serverless services, reducing DB footprint by 24×, and cutting cold-start latency by 40% while mentoring teammates and driving cross-team API integrations.

My work includes building a 3.2B+ daily-request Kafka feedback infrastructure, multi-threaded ingestion pipelines, real-time anomaly detection with Kafka Streams, and Prometheus+Grafana observability stacks that halved MTTR. I contribute to open source projects, build automation tools, and emphasize measurable impact in production systems.
