Bucharest, Romania · A record of my work

Ionut
Ionescu

Computer-engineering student building across the whole stack — from embedded Rust and C/C++ on bare metal to FastAPI and ASP.NET backends.

Currently a research assistant on SISTINA, an antiproton-annihilation physics experiment.

Profile

A short read on who I am and what I work on.

A record of what I've built so far — mostly things close to the metal and the systems that sit on top of them.

I'm an engineering student in the CTI – IoT track at the National Polytechnic University of Bucharest, studying in the Faculty of Engineering in Foreign Languages. Most of what I build lives on GitHub — embedded firmware in C/C++ and async Rust on the Embassy framework, and backend REST services in FastAPI, Flask and ASP.NET.

I'm comfortable taking a project from bare-metal firmware all the way to a Dockerised deployment. A networking foundation (CCNA) and a competitive-informatics background round out how I think about systems. Right now I'm also a research assistant on SISTINA, an antiproton-annihilation physics experiment.

Hall of Fame

The projects I'm most proud of, straight from GitHub.
★ Flagship WEATHER DATA · REST API
01 Python · REST API
Meteo Station REST API
ionutz04/REST-API_Meteo_Station

A backend REST API serving live readings from a weather (meteo) station — built the way I like backends: clean REST endpoints, a persistent data store, and measurements ready to query, chart, or feed into other services.

Experience

Where I build, research, and keep systems running.
2025 — present
Physics & Chemistry Research Assistant
SISTINA Experiment

SISTINA — Strong Interaction Studies in Antiproton Annihilation is an experimental prototype investigating the strong nuclear interaction through antiproton annihilation. I assist on the physics and chemistry side of the prototype — supporting setup, measurements and lab work as the experiment is built out.
