Backend
Services, APIs and the systems that hold things together.
About
Backend Developer · Go / Python
EryyynIT is the public identity. Michael is the person behind it — and this page is the longer answer to “who is this?”.
The story
The public identity and the person behind it — no filters.
EryyynIT is the name I develop under — pronounced roughly like “Eryn”, with an IT suffix, because that's the technical side of me. On a first-name basis, I'm Michael.
I build backend systems end to end. Commercially that means Python and FastAPI, with Go alongside. The rest of the time: infrastructure, small games, AI experiments, and anything that starts with an idea and ends with something that runs.
This site is my hub — the work, the game, and where I share the process. No buzzwords, no fake seniority; just what I build and how I build it.
What I build
The technologies support the work — they don't define it.
Services, APIs and the systems that hold things together.
Getting things to build, ship and stay observable.
AI tools, game prototypes and small things built to learn something.
Right now
Rough edges included.
