// Spring Boot · Kafka · Microservices · AWS · PostgreSQL
I build production-grade backend systems that handle real load — event-driven architectures, distributed microservices, and APIs that don't fall apart at scale. Based in New Delhi, India. Open to remote engagements worldwide.
I'm a Java backend developer with around 4 years building real production systems — not demos, not side projects. I work on the kind of infrastructure where failures cost money and scale is non-negotiable.
My core stack is Spring Boot, Apache Kafka, PostgreSQL, Redis, and AWS. I've designed event-driven architectures, built Spring Batch pipelines for 500K+ records, led Java 11→17 migrations in production, and architected microservices that stay up when things go wrong.
I have a rare specialisation in EV charging infrastructure — including OCPP protocol compliance — which very few Java developers globally have in production. This gives me deep domain knowledge in energy, IoT, and fleet management systems.
Outside of Java, I'm actively learning Python and AI/ML engineering (LangChain, FastAPI, vector databases) to bridge backend expertise with the AI layer that every product now needs.
Every project below is running in production with real users. Not tutorials. Not prototypes.
End-to-end backend for an enterprise EV charging management platform. Real-time Kafka event pipeline, hierarchical PostgreSQL data modeling, Redis caching, and REST APIs serving enterprise fleet clients.
Event-driven batch processing system for enterprise identity data. Kafka consumer queues for high-concurrency ingestion, Spring Batch jobs generating ZIP/CSV archives for 500K+ identity records with sub-second latency.
Backend for an OCPP protocol compliance testing platform, validating EV charging station firmware against the international standard. WebSocket-based communication with Jetty, automated compliance test execution.
REST API backend for distributed power grid management — customer, asset, and site lifecycle operations. Improved system stability and uptime through root cause analysis and targeted fixes across 10+ production issues.
Available for freelance projects, contract roles, and full-time opportunities. I respond within a few hours.
