SEEKING WORK | Berlin (CET/CEST) | Remote | Senior Full-Stack & Cloud Specialist | Part-Time (24h/week)

I’m a senior developer and infrastructure consultant with 15+ years of experience — available for part-time work (24h/week). I help teams move fast without breaking things, bringing deep infrastructure expertise alongside strong full-stack execution.

What I Do Best:

• Cloud & Infrastructure: AWS (primary), Azure, GCP, Terraform, Kubernetes, Serverless, CI/CD (GitHub Actions, etc.)

• Delivery-First Mindset: Recently helped a client setup up CI/CD, staging, and production environments via Kubernetes and compliant — from scratch to deploy — in just 3 weeks part-time

What I’m Looking For:

Teams with meaningful technical challenges — ideally past the MVP/PoC stage and ready to do things properly. I’m most effective where there’s a need to scale infra, clean up dev workflows, or modernize architecture.

Engagement Style:

• Part-time (24h/week)

• Open to short/middle term high-impact contracts, retainers, or embedded support

• Happy to mentor as part of the engagement
