@ankurgangwar
I build reliable backend services, payment ledgers, automation frameworks, and scalable data pipelines.
IndiaWhat I'm looking for
I've built production backend systems at C-DAC, including an append-only coin wallet and ledger service that guarantees exactly-once crediting under retries, crashes, and concurrent requests.
I also delivered advertising, retrieval-augmented assistant, and modular platform backends spanning authentication, social content, marketplace settlement, leaderboards, referrals, queue-backed workers, and abuse detection.
Previously, I improved C-DAC's Logstash and Elasticsearch platform, cutting device-scoped investigation index scope by over 90%, and reduced a CSV correlation job's runtime by over 90% at Surya Fintech.
