I build high-traffic Python APIs and microservices that improve performance, reliability, and cloud efficiency.
IndiaWhat I'm looking for
I've delivered Python services for Google/HCL, Verizon/Infinite Computer Solutions, Mindtree/LFG, and TCS/IBM through Emonics LLC. My work improved application search performance by 78%, reduced database costs by 23%, and increased policy-lookup efficiency by 29%.
I build REST APIs and microservices with FastAPI, Flask, Django, AWS, GCP, PostgreSQL, Spanner, and BigQuery. I'm also designing a fintech wallet service around a double-entry ledger, optimistic concurrency control, idempotency keys, and Alembic migrations.
