What I'm looking for

I seek senior technical roles in MLOps, AI platform, or DevOps where I can lead model optimization and inference infrastructure, mentor engineers, and deliver scalable, production-ready systems — remote or hybrid preferred.

I am an AI and DevOps-focused full-stack engineer with deep experience building MLOps and inference platforms, Kubernetes-based infrastructures, and distributed services. I have led custom Kubernetes development, model inference engines in Rust, and production model optimization pipelines while driving performance and reliability improvements.

My work has produced tangible outcomes—winning a company Innovation Breakthrough Award, contributing to an NVIDIA case study, and presenting at DataFun. I enjoy learning new technologies quickly, sharing technical knowledge, and delivering end-to-end solutions from smart contracts and Web3 apps to large-scale AI platform engineering.
