Background

Hello! I'm Erwin. I architect robotics and AI systems — which in practice means I spend my time on the seams: the places where a planner meets a controller, where a model meets a tool, where a fleet meets the operator who is supposed to trust it. My path started in Nantes, France with electronics and embedded systems, detoured through backend engineering, and landed where I always wanted to be: teaching fleets of robots to make decisions together.

Today I lead autonomy teams at SIRB.AI and the Technology Innovation Institute, where nine engineers and I build decentralized autonomy frameworks for heterogeneous drone swarms — navigation, perception, orchestration, and the infrastructure that keeps it all flying. On the side, I build agentic AI and blockchain tooling at Unchained Labs.

The thread through all of it is the same instinct: push the decision to the edge, make the process reproducible, then get out of the way. It's why my drones have no leader, why my agents get tools instead of instructions, and why my laptop rebuilds itself from a text file. When I'm not shipping autonomy stacks I'm playing basketball, watching films, or chasing ranked ladders.

Here are a few technologies I've been working with recently:

  • C++ / C
  • Python
  • Go
  • Rust
  • ROS 2
  • PX4 / MAVLink
  • Motion Planning
  • Sensor Fusion
  • Agentic AI / MCP
  • TypeScript / React
  • Solidity / EVM
  • Docker / CI

Trajectory

Eight years, four countries, and — right now — three roles running at once. Select a row for the detail.

Lead Robotics Engineer @ SIRB.AI

2026 — Present · Abu Dhabi, UAE

  • Lead the autonomy team at a defense-technology startup spun off from the Technology Innovation Institute.
  • Agentic generation of missions for surveillance, monitoring, and tail chasing.
  • Architecture and algorithm development for decentralized swarm control and multi-agent planning.

Selected Builds

Three altitudes, one idea. A swarm decides without a leader; an agent decides with tools instead of a human; a machine rebuilds itself from a text file. Different problems — the same instinct about where decisions belong.

in the field

Bird-Inspired Flocking

Decentralized, acceleration-based flocking for drone swarms, inspired by how starlings murmurate. Each agent decides from local observations only — no leader, no central brain — yet the flock moves as one. Published at IEEE/RSJ IROS 2024, and the reason the hero of this site is a boids simulation.

t212-mcp

A Model Context Protocol server that gives AI assistants read-only access to a Trading 212 investing account — balances, positions, dividends, pies, and the instrument catalogue. Strictly no trading: the HTTP client has no code path that issues anything but a GET, which is a design constraint rather than a policy note.

setup

One curl command turns a bare Ubuntu box into my entire working environment — shell, toolchains, containers, editors, and dotfiles via chezmoi — then hands off to the app layer. Ansible underneath for idempotency, a typed Python CLI so every generated command is auditable before it runs, and a small Flask control plane for composing a config without hand-editing YAML. It dry-runs with --check, and it is how every machine I touch comes to exist.
