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
