Senior developer · Applied AI & backend

Loïc Sénéchal

I help companies integrate AI into their products in concrete ways — agents, automation, customer support — for measurable results.

What sets me apart

Three angles that make me useful where others aren't

Applied AI

LLM agents, business automation, OpenAI integrations — AI plugged into a real problem, not a demo.

  • LLM agents: workflows, customer support, intelligent processing
  • Conversational interfaces: chatbots, business assistants
  • API integrations: OpenAI, open-source models, custom solutions
  • Fine-tuning and prompt engineering applied to the domain

Solid backend & architecture

Systems built to last: clear APIs, microservices, reliable data, maintainable code.

  • APIs and microservices: Node.js, Python, Django
  • Databases: MongoDB, PostgreSQL, MySQL
  • Real-time: WebSockets, RabbitMQ
  • Tested, documented, readable code over the long run

3D & web visualization touch

When the project needs more than forms: real-time 3D in the browser, configurators, immersive interfaces.

  • Interactive applications with Three.js / WebGL
  • 3D product configurators
  • Immersive and innovative interfaces
  • Optimized Blender → Web pipeline
