# Chandrakant Kumar on Tal

## Headline

SDE 3 \| Java, Spring Boot, Kafka, AWS, Microservices, Distributed Systems MCP \| Building high\-scale fintech & backend systems \(50M\+ events/day\)

## About

I'm Principal software engineer with 8 years of experience designing and owning high\-throughput, event\-driven systems in fintech, currently operating at 50M\+ events/day in production\. At mPokket, I lead two teams responsible for the backend platforms behind marketing/lead conversion and disbursement & rewards — architecting 10\+ microservices on Java \(Spring Boot\) and Kafka, and driving system design decisions end to end\. What drives me is building systems that hold up under real\-world pressure: low latency, fault tolerance, and correctness at scale\. I've cut API latency by 40% \(\~500ms → <300ms\) through Redis caching and async processing, improved reliability by 40% with Kafka\-based retries, DLQs, and idempotent consumers, and migrated a legacy PHP disbursal system to Spring Boot for a 50% performance gain\. I've also led multi\-bank integrations — including HDFC — for secure, fault\-tolerant transaction workflows, and built a rewards/coupon ledger system handling gem\-based earn\-and\-spend transactions across Kafka, Redis, PostgreSQL, and MongoDB\. My core stack is Java 17\-21, Spring Boot, Kafka, and AWS \(EC2, Lambda, MSK, RDS, DynamoDB\), with PostgreSQL, Redis, and MongoDB for data, and Python \(FastAPI/Django\) in the mix for select services\. I'm also exploring how Gen AI/LLM integration fits into backend architecture and developer workflows — an area I see becoming central to how platform teams operate\. I'm open to Principal/Staff\-level backend and platform engineering roles where I can keep working on systems at scale\. Happy to connect and talk distributed systems, Kafka architecture, or fintech backend engineering
