Hi, my name is

Houssem

I am a Cloud ☁️ a whisperer by day, code tamer by night 🤠 — I architect things that live on the web and run in the cloud.

My name is Houssem Charfeddine, a software engineer who happened to get paid for his hobby. I am passionate about computers ever since I was little, my favorite quote is by Harold Abelson “Programs must be written for people to read, and only incidentally for machines to execute.”

About Me

A highly motivated, adaptable and responsible professional who is passionate about Cloud and thrive from challenges.

I am an experienced Engineer, who specialize in designing scalable and cost-efficient cloud solutions while maintaining performance and reliability. I pride myself in crafting architectures that optimize FinOps practices that align with overall business objectives. What truly sets me apart is my ability to bridge the gap between engineering and business. I’m equally comfortable debugging Kubernetes issues as I am explaining architecture decisions to stakeholders or translating technical requirements into strategic value. I bring clarity to complexity and foster collaboration across disciplines to drive outcomes that matter.

Here are a few technologies I've been working with recently:
  • Kubernetes
  • Helm
  • AWS
  • Terraform
  • Vault
  • Docker
  • Linux
  • GitHub Actions
