Description

I build tools that automate what wastes your time.

After 8 years in critical infrastructure at Apple (Cork) and Sanofi (Paris),

I specialized in Python development, LLM integration, and AWS cloud deployment.

I deliver systems that run in production 24/7 — not POCs.

What I can build for you:

- Python automation bots (scraping, data processing, alerts)

- Custom API integrations (REST, WebSocket, webhooks)

- Autonomous LLM agents (OpenAI, Anthropic, Groq, Ollama)

- Real-time dashboards with FastAPI + WebSocket

- Turnkey AWS infrastructure (EC2, systemd, monitoring)

Recent projects: autonomous algorithmic trading platform (Python, AWS EC2, real-time dashboard), LLM-based coding CLI agent.

Remote only. Response within 24 hours.
