I will create hardware prototypes, arduino programming, esp32, embedded systems

Need a working hardware prototype or help with an existing Arduino or ESP32 project?

I develop electronic prototypes and firmware, connecting sensors, displays and controls with the software and enclosure your project needs.

Depending on the agreed scope, I can help with:

• Arduino and ESP32 programming and debugging
• Sensors, actuators, displays and WiFi/BLE connectivity
• PCB design and component integration
• CAD, custom enclosures and 3D printing
• Local ESP web interfaces and connected web or mobile apps
• Prototype assembly and functional testing

You can start with a defined programming task or discuss a complete prototype. Each package covers its stated scope; additional features are quoted separately. Materials and shipping are additional and agreed before ordering.

We agree on deliverables, milestones and test criteria before work starts, with progress updates during development.

Message me with your idea, existing files or hardware, required functions, budget and target date. I will help define a practical next step.
