Hi, I'm Yewolf 👋🏻

Hi, I'm Yewolf, currently a Software Engineer at Infomaniak in Geneva, Switzerland. I specialize in Go and distributed systems development, focusing on creating efficient cloud infrastructure and services with a sustainable approach.

As a certified Kubestronaut, I've developed deep expertise in containerization, Kubernetes administration, cloud native security, and distributed systems. I enjoy solving complex problems, optimizing performance, and building reliable systems that scale effectively. This portfolio itself is built using a scale-to-zero architecture, demonstrating efficient resource utilization and cost optimization in modern cloud deployments.

At Infomaniak, I'm currently working on cloud infrastructure after successfully completing an internship focused on custom branding using K8s, Go, and Laravel. My GitHub showcases various personal projects including the Terraform Provider for Infomaniak, Go CD for continuous deployment, and other utilities. Check out my GitHub profile to see my work.

About This Site

Scale-to-Zero Architecture

This portfolio website is built using a modern scale-to-zero architecture, leveraging technologies like:

Static site generation with Astro, ensuring fast load times and optimal performance
Deployment on serverless platforms that automatically scale down to zero when not in use
Optimized asset delivery and minimal JavaScript for reduced carbon footprint

This approach demonstrates my commitment to efficient resource utilization and cost optimization in cloud deployments. The site consumes resources only when being accessed, reducing both costs and environmental impact.
