From a real problem to a working application
I work across software, data, integrations, and operations. The projects here show how those pieces fit together.
I build applications around work that deserves better tools: managing club members, checking cash records, understanding personal finances, or connecting infrastructure to its owners and costs. I take a project from its data model and interface through integrations, deployment, and maintenance.
My background in Linux, networking, and virtualization informs how I build software. I care about clear ownership of data, recoverable changes, and records that people can check later. Recent work includes Fortuna, Kontor2, Kataster, Rendant, Sigil, and DiaTrack.
Software, data, and operations
What I work with
Cloud infrastructure
I run production workloads on Railway and Hetzner: deployments, databases, and the networking glue that keeps them online.
Applications and data
TypeScript, React, TanStack Start, and PostgreSQL. I connect interfaces, validated APIs, and domain logic into applications that people can use.
Linux and automation
Red Hat Certified System Administrator (EX200). I manage Linux servers and automate the repetitive parts with Ansible, Bash, and Python.
Networking
Comfortable from DNS and mail security up to datacenter switching, with a focus on reliable, well-understood setups.
Get in touch
Happy to talk about a useful application, a complex workflow, or the infrastructure behind it.
