Freelancer profile translated to English.

Description

Full-stack and data engineer, I build complete products — from data pipeline to interface — with extensive practice in AI-assisted development (agents, RAG, LLM integration).

Currently at Leroy Merlin, where I delivered a geo-marketing platform used by 150 active users/week (Vue 3, FastAPI, GCP, Kubernetes) and ETL pipelines enriched by GenAI on 15+ public datasets.

On the side, I undertake projects requiring performance and reliability: Rustyleaf, an open-source mapping engine in Rust/WebAssembly/WebGL2 published on npm, which runs at 60 fps displaying 1 million points (~37x faster than Leaflet's canvas renderer); and a sports market quantitative analysis platform — asynchronous scraping of 8+ real-time sources, backtesting on 100,000+ events, statistical calibration.
