Hi, I'm Thomas Chaigneau πŸ‘‹

Founder & AI Engineer β€” building and operating AI products

πŸ‡«πŸ‡· Based in France Β· Working B2B Β· Shipping production AI


πŸ‘¨β€πŸ’» What I do

I'm a bootstrapped founder and AI engineer focused on building AI systems that actually ship.

  • I work B2B with startups on production AI systems (LLMs, data pipelines, infra)
  • I build my own products alongside client work
  • I care a lot about simplicity, cost control, and real-world constraints

πŸ“« Contact: thomas@chainyo.dev


πŸš€ Current work

  • Founder β€” LocalClip.app
    Building a local-first tool for content creators
    Product, engineering, distribution

  • AI Engineer (B2B)
    Working with a US health startup on production AI systems
    Focus on delivery, scalability, and cost efficiency


πŸ† Selected achievements

  • Built and deployed production ML systems end-to-end (training β†’ API β†’ infra)
  • Led large-scale model optimization & inference pipelines
  • Contributed to open-source ML tooling and model deployment workflows
  • Designed internal tools and demos to make ML usable by non-ML teams
  • Co-founded a local cloud / ML community group (AWS-focused)

(Older OSS / fellowship work is still visible in repositories and commit history.)


✍️ Writing & thinking

I sometimes write about:

  • shipping AI to production
  • infra tradeoffs
  • build vs buy decisions
  • common mistakes teams make with LLMs

Some articles I wrote on Medium:


🧰 Tools I use (not exhaustive)

  • AI / Data: PyTorch, Hugging Face, ONNX, scikit-learn
  • Backend: Python, FastAPI, Hono
  • Frontend: TypeScript, React, Svelte
  • Infra: Docker, Cloudflare, AWS
  • Databases: Postgres, SQLite, Redis

(Choice of tools depends on constraints β€” I don’t believe in fixed stacks.)
