About

I’m a Senior Backend Engineer with 6+ years of experience working on credit, authentication, and risk platforms in fintech. I have built and scaled production tested risk and offer engines operating at 5000 RPS with DAU of 10 million. Led and mentored junior engineers and peers on best practices in fintech engineering , taking tradeoffs between consistency and availability on network partitions I own Credit, Risk and Authentication Backend System end to end from last 5 years — from design and scaling decisions to on-call firefighting at 3 AM In my free time i like to explore AI technologies especially RAG and agentic AI

Fixed JVM shutdown blocking issues in Apache Fury by converting background worker threads to daemon
threads, reducing shutdown latency by 5 seconds.
Debugged and resolved ARM-specific serialization failures caused by unsafe memory alignment on JDK 25.
Collaborated with maintainers to validate thread-safety and confirm no impact on data consistency during early shutdown.

I own end-to-end backend systems for Credit and Authentication platforms, scaling traffic from 10 RPS →
5,000 RPS with DAU of 1 Million, while maintaining 99.99% availability.
Identified thread contention, DB hot partitions, and Cache misses as primary bottlenecks and redesigned loan
offer service using asynchronous execution, multi threading, and 3-level caching which led to 3x faster offer
generation
Led the Design of fault-tolerant MFA Authentication Service with DAU of 10M users using JWT, Google SSO,
and DynamoDB, serving 5,000 RPS with token bucket rate limiter.
Delivered a fraud detection engine for loan applications by putting behavioral, and historical data into a
risk-scoring engine saving around 1 million dollar annually.
Improved JVM performance across critical services by tuning G1 GC parameters, reducing GC pause times by
50% and increasing throughput by 20%.
Designed event-driven Audit workflow using Kafka for credit system, ensuring idempotent processing, retries for
critical financial events.
Actively participated in on-call rotations, have handled 20+ Sev-0 issues occuring due to database throttling,
downstream failures, thread contentions, etc .
