Pierre G.

Software architect and full-stack developer (10+ years of experience). My cross-domain profile allows me to work on SaaS platforms, 3D game engines, complex e-commerces, or R&D projects.

I adapt quickly to the requested environment.

My areas of expertise:

Web, SaaS & E-commerce Architecture

- Robust full-stack development (Python, FastAPI, Next.js, Supabase, PostgreSQL).

- Creation and migration of custom e-commerces (advanced Stripe integration, automations).

- Code takeover, security audits (Row Level Security), and refactoring of asynchronous architectures.

Game Development, XR & Interactive Engines

XR Software Architecture (Unity / Unreal Engine 5): Design of LBE platforms (Free-Roam VR), B2B industrial simulators, and corporate experiences under NDA (Middle East).

Networking & Multiplayer: Integration of Host-Client topologies (Photon, NGO) for very low latency virtual environments and spatial co-location.

System Development: Modular structuring (C++, C#), creation of serious games, procedural narrative engines (PCG), and interconnection with complex backends (APIs, databases).

AI Engineering & Automation

- Pragmatic AI integration (Claude, OpenAI, Mistral) with strict cost control and hallucination management.

- Creation of complete RAG pipelines coupled with vector databases (ChromaDB).

- Workflow automation (n8n) and local agent deployment.

Proof of Work & Portfolio:

Some of my work is detailed on wonderfularcane.vision

Recent projects: Materya.fr, Industrial Security Simulator on a sensitive site (complete AI SaaS with asynchronous backend, RAG, and encrypted data), custom e-commerces, and AI narrative engine prototypes (behavioral degradation managed by LLM).
