I’m a Backend Software Engineer with 3+ years of experience building and scaling high throughput distributed systems processing $30M+ monthly transactions at 99.9% uptime. I own the full feature lifecycle—from system design and API contracts to production reliability—so teams can ship confidently.

At Amdocs, I architected Java Spring Boot microservices powering high-volume payment workflows for 500K+ users across distributed financial systems. I reduced production incidents by 40% through observability redesign, standardized alerting thresholds, and structured RCA workflows that permanently improved the codebase.

I focus heavily on performance and release quality: I resolved critical N+1 query patterns and missing index strategies in Oracle/PostgreSQL, cutting p95 API response times by 35%+ under peak load. I also built an end-to-end test automation framework that eliminated 50% of manual QA effort and reduced support overhead by 60%, while maintaining zero production-blocking defects across releases.

I enjoy driving system design decisions that get adopted across the team—defining service boundaries, REST API contracts, and DB schemas for new billing modules. I’m especially motivated by hard engineering problems at scale, combining distributed systems, SRE, and performance engineering to build resilient platforms.
