01 . Architecture & Philosophy

Designing For Scale & Speed

I design reliable fintech systems. My platforms are architected for low-latency transaction routing, zero connection pool exhaustions, offline-first syncing, and massive events/payout scaling.

Fintech Core & SDKs

Architected a low-latency Payments SDK pairing offline-first POS devices with payment terminals, reducing integration friction by 40% and accelerating sprint velocities across merchant systems.

High-Scale Database Sharding

Designed cross-regional distributed tables using PostgreSQL partitioning and FDW, plus AWS RDS Proxy connection pooling to systematically eliminate connection exhaustion bottlenecks.

Resilient Event Ingestion

Led the monetization technology squad at Bajaj FinServ managing 8 event-driven microservices processing 850K+ daily transactions at 99.9% uptime, slashing system latency by 65%.
