I’m a Java Backend Engineer with 4 years of experience building scalable enterprise SaaS and IAM platforms from scratch. I take end-to-end ownership across the development lifecycle, pairing strong OOP foundations with design patterns, system design thinking, and practical problem-solving.

At miniOrange (Pune, India), I led backend development of a multi-tenant data scanning engine using Java, Spring Boot, and microservices for 150+ enterprise customers. I re-architected the data scan pipeline with Spring Batch and Kafka for parallel execution across distributed workers, reducing average scan time by 32 minutes, and engineered thread-safe execution using Java multithreading and Redis distributed locking to handle production concurrency—enabling 20+ simultaneous enterprise scans.

I focus heavily on performance and reliability: I optimized PostgreSQL schemas and introduced Redis caching for high-frequency queries, cutting API response times from 2s to 20ms under enterprise workloads. I also built enterprise SSO authentication with Spring Security (SAML 2.0, OAuth2, JWT) and implemented SCIM provisioning to eliminate manual onboarding workflows, while mentoring 8 junior engineers through code reviews and architecture discussions.
