What I'm looking for

I’m looking for a backend role where I can build scalable Java/Spring microservices, own performance and reliability, and collaborate across teams to deliver zero-downtime migrations and measurable improvements.

I’m a Backend Engineer with 2 years of experience at UKG, architecting scalable, high-performance backend systems and microservices using Java, Spring Boot, and distributed system design. I enjoy owning end-to-end engineering—from system design and security to production reliability—while keeping performance and maintainability front and center.

At UKG, I led end-to-end Auth0 migration for 500+ enterprise clients with zero downtime, engineered systems handling 300K+ concurrent users, and delivered measurable results: 40% improvement in data retrieval, 30% reduction in processing time, and 15% faster API response. I’ve also maintained a 99.9% uptime SLA and resolved 10+ critical production defects through debugging, root-cause analysis, and performance profiling.

I bring a hands-on, quality-driven mindset from internships and projects—optimizing Django admin panels and ORM queries for faster retrieval, and building real-time, secure features in an open-source NGO platform. Beyond backend, I’ve built an ML pipeline for fake review detection and earned 6 performance awards for technical excellence and cross-functional collaboration.
