What I'm looking for

I seek backend/GenAI roles where I can modernize legacy systems, build scalable cloud-native services, and apply statistics to improve model and pipeline performance.

I am a software engineer with a B.S. in Statistics who bridges deterministic backend engineering and probabilistic GenAI systems, focusing on Golang and Java for enterprise-grade solutions.

I've built high-scale Golang microservices sustaining 99.99% uptime, engineered AI agents and multi-model gateways to modernize legacy monoliths, and improved LLM-driven refactoring accuracy and developer productivity.

I combine applied statistics, distributed systems experience, and cloud-native practices (AWS, Docker, Kubernetes, CI/CD) to deliver scalable, data-informed systems that reduce latency and accelerate delivery.
