What I'm looking for

I’m looking for a role where I can own system architecture for scalable backend microservices, optimize low-latency data layers, and build resilient automation in multi-cloud environments—shipping measurable performance improvements with strong engineering discipline.

I’m a highly analytical, results-driven Senior Software Engineer with 6+ years of industry experience and an ongoing PhD in Computer Science. I specialize in system architecture, highly scalable backend microservices, and optimizing complex database workflows—turning messy requirements into resilient, production-ready solutions.

Most recently, I designed and built multi-agent distributed system workflows and core text orchestration engines from scratch, integrating dense + sparse hybrid queries to boost retrieval accuracy by 40%. I also engineered high-throughput backend data-processing pipelines—automating multi-source structured mapping to reduce processing cycles by 35% and support 500K+ records per run. To keep systems stable under real load, I implemented structured CI/CD pipelines and cloud-native monitoring across AWS and Azure.

Earlier, I helped deliver enterprise automation pipelines by eliminating serialization bottlenecks, reducing end-to-end latency by 45%, and integrating re-ranking tiers to improve streaming API payload performance by 32%. I’ve also built telemetry and prediction platforms, redesigned NLP parsing frameworks to reach 93% accuracy, and automated high-volume content generation to accelerate production speed by 50%, while maintaining strong reliability and traceability.
