What I'm looking for

I'm looking to build reliable, revenue-critical distributed systems and multi-cloud platform services, with opportunities to lead technical design, improve production reliability, and automate complex operational workflows.

Software engineer with 4+ years building revenue-critical billing, marketplace and usage-metering services across AWS, Azure and GCP. At NetApp I shipped a Backcharge Tool that recovered about $1.5M in missed billing revenue, cut critical microservice failures from 57% to 0.2%, and built fault-tolerant payment workflows (retries, DLQs) that reduced failed-event revenue loss by 25%. I also led a team of 4 through a billing service launch, migrated authorization to a centralized RBAC service, and built an MCP-based AI assistant that cut manual debugging effort by 60%.

Earlier, at Happiest Minds, I built Python and Node.js services processing 1M+ records daily, ETL pipelines, and async REST APIs. Stack: Python, Go, TypeScript, PostgreSQL, MySQL, Redis, Kafka, Kubernetes. I like solving reliability problems with practical architecture and automation.
