Code is a craft. Teams are a multiplier. I obsess over both.

🤖 Robotics Hobby

Forking & extending an open-source robot project — going well beyond the original scope:

• 📷 Camera module — real-time visual input
• 🧠 AI integration — embedding ML models for autonomous behavior
• ⚙️ Firmware improvements — motion control & hardware extensions
• 🔧 New sensor capabilities — expanding what the robot can perceive

Frontend is where I work. Robots are where I think differently.
