I build scalable backend platforms for polling, surveys, search, and investment workflows.

At Simpplr, I own backend development for employee listening, building real-time polling, surveys, reporting, and audience-management services. I architected four polling services tested at roughly 50K concurrent users and migrated APIs from AWS Lambda to microservices, cutting the slowest response time from about 14 seconds to 350ms.

Previously, I built investment workflows at Lendbox and diagnostic search, order, and notification systems at PharmEasy. I work across Java, Spring Boot, distributed systems, Kafka, Redis, Elasticsearch, and cloud-native services, and I’ve mentored 5+ new hires as they ramped up on production engineering.
