Michael Ramstein — CTO at TechDock, DevOps at Helvetia Baloise Group. Basel.

DevOps person at heart: I automate what can be automated and put an API on everything else.

• TechDock: industrial machines reachable from anywhere — remote access, M2M, monitoring
• Helvetia: platform work on OpenShift with ArgoCD and Terraform, Quarkus services, AI since 2025
• Before: seven years at cyon, the Basel web host, from software engineer to head of software engineering

After hours I write Elixir, build my computers with Nix and reverse-engineer gadgets until they talk to me.

• Elixir firmware for TechDock's next gateway generation
• NixOS on a Framework 13, declarative down to the firmware
• Agent loops that turn GitLab tickets into reviewed merge requests

updated 2026-10

~ $ ls ~/work/techdock

TechDock's M2M cloud lets technicians reach machines in the field without driving there. I build and run most of it:

platform

Remote-access and fleet platform (PHP/Laravel), since 2019

client

Windows client for remote sessions (C#/.NET)

gateway

Linux gateways: firmware and services in Elixir

opc-ua

OPC UA client libraries for PHP

infra

Terraform, Ansible and Nomad; devices provisioned with Nix

agents

Headless Claude lanes that implement, review and gate tickets
