Senior Software Engineer

Bajaj Finserv

Jan 2025 — Present · Pune, India

  • Engineered performance optimizations for the EMI Card Authorization & Eligibility APIs — sub-100 ms p98 latency while reliably handling 400K+ txns/day.
  • Architected a centralized real-time pre-disbursement fraud detection engine with multi-rule risk evaluation — fraudulent approvals down 15%, an estimated ₹75 Cr/month in losses prevented, scaled across 3 lending products in 6 months.
  • Designed and scaled a distributed document generation scheduler processing 100K+ docs/day (KFS, charge slips, audit trails) — generation time cut from 5 min → 30 s, eliminating manual compliance bottlenecks across the lending lifecycle.

Jul 2023 — Dec 2024 · Pune, India

  • Designed and delivered a unified Partner Service API for co-lending — onboarded 7+ external partners (Airtel, Navi, Cars24) with partner-specific contract handling, reducing average integration time.
  • Automated salary structure generation for 2000+ employees via a REST API for the HRMS platform — eliminated manual Excel-based computations and streamlined HR decisions across hiring, promotions, and transfers.

03 — how I think

Anatomy of the fraud detection engine.

A simplified view of the real-time pre-disbursement pipeline I architected — every loan request is risk-scored in-flight, before money moves.
