Hey, i'm Hez.

Welcome to my website!

I'm a Backend / DevOps Specialist focused on distributed systems and microservices 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 attackers' perspective with Cyber Security add-on to that work, with 20+ web application penetration tests experience and eJPT certification in progress. I also architect backend systems for AI/ML (MLOps) spanning pattern analysis, forecasting, LLMs/RAG, and Computer Vision. At the side I also build SaaS and Security Tools.
