about

I'm a Tech Lead with a passion for building scalable systems, automating workflows, and shipping high-quality software.

Currently, I work at Swiss Premium Negoce SA (2021–Present), where I:

  • ▸ Design and manage cloud-native architectures with Kubernetes
  • ▸ Build secure infrastructure for cloud, backend and frontend servers
  • ▸ Implement CI/CD pipelines with Argo Workflows and ArgoCD
  • ▸ Develop servers with circuit breakers, caching, and rate limiting in Go

This portfolio website is my playground — built during my spare time — where I experiment with new tools, frameworks, and ideas.

Have fun exploring my projects, tools and play my games!
