What I'm looking for

I seek backend roles focused on scalable, data-intensive systems, strong engineering practices, collaboration with cross-functional teams, and opportunities to optimize performance and reliability.

I am a backend software engineer with 3+ years of hands-on experience building event-driven, data-intensive backend systems using Java (17), Spring Boot, and Apache Kafka. I focus on clean, maintainable code and delivering reliable solutions that improve performance and scalability.

At Solulever I engineered a multi-tenant architecture, onboarded 10+ clients, built a dependency-aware scheduler and rule engine with per-KPI execution isolation, and optimized PostgreSQL query performance from 30s to 2s through indexing and query fixes. I also implemented Redis caching and centralized Audit Trail & Workflow services while enforcing RBAC via Spring Security.

Previously at Nagarro and Vectoscalar I designed and implemented 15+ RESTful APIs, resolved numerous production bugs, tuned database indexes for large datasets, and standardized CI/CD and branching flows to make deployments predictable. I collaborate closely with frontend and QA teams to align API contracts and accelerate delivery.
