Your server's down, your Docker containers won't start, or your deployment pipeline breaks every push. I fix that — fast. What I've built and managed: → Ran a hosting startup with 100+ active servers, client domains, and the 2am emergencies that comes with it. → Deployed an IoT energy platform at Avrio Energy: Dockerized backend, JWT auth APIs, CI/CD pipelines, NGINX + HTTPS - still running in production. → Daily work: Linux administration, bash automation, AWS/GCP infrastructure, Kubernetes clusters, Terraform deployments. I respond within hours, document everything, and don't ghost mid-project. Server broken? Deployment stuck? Message me what's wrong.
