I build Java and Spring Boot services for enterprise products, with recent work across APIs, caching, document workflows, and multi-tenant data flows at SAP.
About
Profile, engineering focus, and tools I reach for most.
Software engineer with 5+ years across enterprise products in India and Germany, focused on backend systems that need to stay reliable under real production load.
- •Most of my work sits in Java and Spring Boot services, data access layers, integration-heavy features, and APIs used by large enterprise tenants.
- •Recent projects have included paginated retrieval paths, caching for read-heavy flows, document generation, and tenant-aware replication or migration work.
- •I spent 3 years in Germany at SAP and now work from Bengaluru, bringing a mix of enterprise engineering discipline and pragmatic product delivery.
- •Outside work I read about systems, play competitive games, and still enjoy tracing a bug further than strictly necessary.
