Jan 2026 - Present

Developed and maintained 80+ REST APIs using Python, FastAPI, PostgreSQL and SQLAlchemy; validated request/response contracts, status codes and JSON payloads with Postman before release. Built and enhanced 40+ backend modules (campaigns, deliverables, vendor workflows, order tracking, payouts, analytics, third-party integrations) while handling edge cases like invalid inputs and failed integrations. Implemented JWT authentication and RBAC across 3 user portals (Brand, Vendor, Admin) and verified access restrictions for each role. Used SQL and SQLAlchemy to validate and optimize GST distribution, payout and campaign-cost calculations, checking application outputs against database records. Implemented Redis-based login-attempt tracking and rate limiting to harden API security. Worked across the SDLC/STLC in an Agile team: reviewed requirements, investigated defects, performed root-cause analysis, verified fixes and communicated impact to developers, product and QA.
