About

I've been a full stack engineer for 12 years now, with advanced expertise in TypeScript, PHP, C# and DevOps.

Over all those years, I've transitioned from designing website layouts to developing robust web applications, aiding businesses in expanding their customer base and revenue. My expertise also extends to DevOps; I've architected and maintained clusters hosting hundreds of services with Kubernetes, Docker and Terraform.
