@subashchinnannan
I build reliable billing, marketplace, and usage-metering systems for multi-cloud platforms.
United StatesWhat I'm looking for
At NetApp, I build revenue-critical billing and marketplace services across AWS, Azure, and GCP. I shipped a Backcharge Tool that recovered approximately $1.5M in missed billing revenue, reduced critical microservice failures from 57% to 0.2%, and built fault-tolerant payment workflows that reduced failed-event revenue loss by 25%.
Previously at Happiest Minds Technologies, I engineered Python and Node.js services processing over 1M records daily, ETL pipelines, asynchronous REST APIs, and production observability. I enjoy solving distributed-systems reliability problems through practical architecture, cloud-native delivery, and automation.
