About this Gig
Have an idea for a custom MIDI controller, electronic instrument, or LED lighting rig but no firmware to bring it to life?
I'm a firmware engineer who builds custom code for musicians, instrument builders, lighting techs, and makers turning your hardware into a fully functional, responsive device ready to perform.
What I Offer:
- Custom MIDI controller firmware
- USB & serial MIDI implementation
- MIDI mapping (buttons, knobs, faders, pads)
- DIY synthesizer & instrument firmware
- Addressable LED programming (WS2812, NeoPixel)
- LED animation & effects coding
- Music/audio-reactive LED systems
- DMX lighting control firmware
- Relay control & switching logic
- Stage/event lighting systems
- Interactive art installation firmware
- Sensor-triggered effects (sound, light, motion)
- Wireless control (WiFi/BLE for MIDI or LEDs)
- Debugging existing firmware
- Prototype to final build firmware
- Full documentation & source code
Why Choose Me:
- Experience across music tech, lighting, and maker electronics
- Clean, reliable code built for live performance and real world use
- Clear communication and realistic, honest timelines
Share your project details and components let's bring your build to life.
FAQ
Do I need to send you my physical hardware?
No. This is remote work I just need your component list, wiring details, and a clear description of what you want the device to do. You handle flashing and testing on your end.
What platforms do you work with?
I primarily work with Arduino, ESP32, and STM32. Message me with your board details if it's not listed.
Can you build MIDI mapping for my custom controller?
Yes. I can map buttons, knobs, faders, and pads to MIDI messages (USB or DIN MIDI) so your controller works with your DAW or music software.
Do you work with addressable LEDs like WS2812 or NeoPixel?
Yes. I write custom LED animations and effects, including music/audio-reactive lighting synced to sound or MIDI input.
Can you build a DMX or stage lighting control system?
Yes. I develop DMX and relay-based lighting control firmware for stage, event, and venue setups.
Is relay control safe for high-power devices?
I write firmware with proper debounce, timing, and safety logic for relay switching but you're responsible for safe electrical wiring/installation on your end.
Can you fix my existing firmware instead of building from scratch?
Yes. Share your current code and describe the issue (timing problems, flickering, unresponsive controls, etc.) and I'll review it before we start.
