About Me

I'm a backend engineer with a security-first mindset, specialising in Node.js, AWS, and Kubernetes. I design and operate production infrastructure — from zero-downtime CI/CD pipelines and container orchestration to network-layer security with VPCs, WAF, and Cloudflare. I also work with Web3 systems and care deeply about observability, monitoring, and reliability at scale.
