Hey, i'm Hez.

Welcome to my website!

I'm a Backend / DevOps Specialist focused on high-performance, clean system design and production infrastructure who's also comfortable with Frontend (Next.js/Typescript). I work in Go, Python, Node.js, gRPC, Redis, RabbitMQ, Docker, and Kubernetes environments — complete with Terraform, CI/CD, and automated testing — building observable, maintainable, and reliably deployed distributed systems. I bring a Cyber Security add-on to that work, with 20+ web application penetration tests and an eJPT certification in progress, giving me an attacker's eye for the systems I build and deploy. I also occasionally architect backend systems for AI/ML spanning pattern analysis, forecasting, RAG, and Computer Vision.
