About Corentin

What I do (and what I DON'T do)


I don't configure Zapier or N8N blocks. Icodecustom AI automation systems, intelligent agents that understand context, learn from your data, and execute complex workflows without human intervention.

Key difference:An N8N workflow stops when something unexpected happens. An AI agent I develop adapts, makes decisions, and continues.

My Journey:

  • I've been coding since 2018 (I was 13 years old)
  • Graduated from school 42, I've been a professional since 2017
  • Today: I take an idea to a production product in a day using modern AI tools
I contributed to the HyperLiquid SDK (1.5k+ GitHub stars) and built automated trading systems used in production.

What I build


Autonomous AI Agents
  • Intelligent assistants connected to your tools (CRM, email, Slack, databases)
  • Scraping and competitive intelligence agents
  • Contextual automated response systems
Backend Automation

  • Data processing pipelines
  • Complex API integrations
  • Microservice orchestration
Trading & Analysis Systems

  • Algorithmic trading bots
  • Real-time data analysis
  • High-performance infrastructure

Tech Stack


Languages:Go, Python, TypeScript, Solidity
AI:Anthropic, OpenAI APIs, LangChain agents, RAG, Fine-tuning
Infrastructure:Docker, Kubernetes, PostgreSQL, Redis, message queues
Cloud:AWS, GCP, VPS, bare-metal

Why me?


*Speed:I deliver functional MVPs in days, not months

*No no-code dependency:Your system belongs to you, source code included

*Production-ready:I don't build prototypes that break. I build systems that run.
