Software developer with a backend and infrastructure focus. I build and run the whole stack: backend services in Java (Quarkus), Python (Django), TypeScript (NestJS) and Go on PostgreSQL, packaged with Docker and deployed on Linux servers I administer myself, with automatic TLS, CI/CD, monitoring and backups. And I care about software that respects the people who use it: my own apps work offline, need no account and send nothing to a server.
