01About

Engineer working close to the metal, shipping with intent.

I'm a software engineer with 3+ years of experience building scalable, high-performance Java services and distributed systems. I design data models, define APIs, and ship the caching, async jobs, and observability that keep them honest in production.

I'm currently a BIOS Developer at Light & Wonder in Las Vegas, working close to the hardware on gaming-platform firmware. Before that, I shipped HIPAA-compliant healthcare platforms at UnitedHealth Group serving 200K+ members, led microservices migrations at L&T Infotech, and co-built a hyperlocal delivery startup from zero to 500+ deliveries.

My toolkit is Java, Spring Boot, Kafka, PostgreSQL, and Cassandra — but the through-line is multithreading, real-time pipelines, and the kind of microservice architecture that doesn't page you at 3 a.m.

02Experience

From healthcare platforms to gaming firmware.

A path that taught me to design for trust and ship for outcomes.

UnitedHealth Group
Software Engineer
Noida, India
- ↳Architected and executed a zero-downtime migration of 15 legacy databases into a unified PostgreSQL platform under Agile practices, with a fault-tolerant migration framework: automated rollback, schema mapping, continuous monitoring.
- ↳Implemented real-time, Kafka-based synchronization pipelines achieving sub-0.5s replication latency for millions of records across auth, alert, and contact datasets, with Java services for data validation and integrity.
- ↳Consolidated legacy healthcare systems into a cloud-native microservices platform serving 200K+ members with projected $1.4M annual cost savings and 99.9% uptime.
- ↳Delivered HIPAA-compliant full-stack features: provider search on Elasticsearch (sub-200ms P99 across 500K+ records), real-time SMS, announcement dashboards — Angular, GraphQL, Spring Boot, PostgreSQL.
- ↳Built event-driven observability platform on Splunk, Grafana, and Snowflake, reducing mean-time-to-detection by 40%.
- ↳Led Kafka migration from Azure Event Hubs to GCP (50+ topics, 4M+ events/day); optimized Spring Boot APIs by +35%. Earned a Bravo Award and 5-star performance rating.
