UEFN Developer : Verse Coding and Bug Fixing for Fortnite Maps
France
English, French, Spanish
About me
A lot of Fortnite maps have a solid idea sitting on code that doesn't quite hold up. A mechanic glitches mid-game, or the framerate tanks the second a few players join.
I'm a UEFN developer, and that's the part I handle. I write the Verse behind your map: game loops, economies, NPCs, scoring. It runs properly and it's ready to publish. Most maps need a mix of classic devices and SceneGraph, and I'm happy wiring the two together.
I keep things clear to work with and the code clean enough to build on. Send me your map and tell me what's broken. I'll sort it.

Trading Analytics SaaS
Jun 2022 - Apr 2024 • 1 yr 10 mos
Built the Backend for a web platform that lets traders analyze their performance from market data and trade history. Worked in Python, with data processing pipelines that clean, structure, and aggregate financial time series. Implemented the statistical modules behind the core metrics : drawdown, risk/reward ratio, risk-adjusted performance. I also designed a REST API to feed an interactive dashboard with real-time indicators and performance charts. Architecture was modular by design, splitting the calculation, data, and presentation layers so the system stays scalable and easy to extend.
