Description

Expert in Artificial Intelligence & Sovereign Software Development

Founder of Nexapex, I transform complex problems into high-performing software solutions, with a unique specialization: integrating local AI (LLMs) for total data confidentiality.

My Technical Expertise

Forget expensive API subscriptions. I design optimized architectures to run on local infrastructure (On-premise), following my performance philosophy: VRAM > raw power.

AI & Machine Learning: Deployment and fine-tuning of local models (Llama 3, DeepSeek).

Quantum Computing & Data: Mastery of Qiskit for tomorrow's challenges.

Environment: Native development under Ubuntu 24.04 for maximum production stability.

Stack: Python (PyTorch, TensorFlow), Docker for containerization, and custom hardware integration.

The ORION Project

Initiated as an intelligent voice assistant, ORION is now the laboratory for my innovations in human-machine interaction and critical task automation. This expertise allows me to deliver business tools that don't just exist, but perform.

Why collaborate with Nexapex?

Choosing my structure means choosing the agility of a CESI engineer combined with an unfiltered business vision. I don't just sell code, I sell technological independence and a drastic reduction in your opportunity costs.
