Who I am?

Kyrylo Bublii — backend developer

I write backend code and run the infrastructure it lives on, because software only counts once it is actually running.

I ship and run backend systems: containers, CI/CD pipelines and Linux servers, plus the Python services they carry. Most of my time goes to Docker, Kubernetes and deployment automation — the rest to Flask, FastAPI and PostgreSQL.
