I will design and build a complete electronics prototype on esp32
Turning ESP32, Arduino and Raspberry Pi Ideas into Working Prototypes
I’m a freelance Firmware & IoT Developer with strong expertise in designing and building smart, connected solutions. Over the past few years, I’ve worked extensively with ESP32, Raspberry Pi, Arduino,...
Level 1
Has met certain performance criteria and shows strong potential in the marketplace.
About this Gig
Want to build an ESP32-based IoT device but dont know where to start?
I help founders, hobbyists and engineering students turn their embedded system ideas into fully working hardware prototypes. With a background in electrical engineering, I take care of the entire process from circuit design and PCB design to writing the firmware (ESP-IDF / Arduino) and delivering a tested prototype.
What's included:
- Component selection & Bill of Materials (BOM) for ESP32
- Circuit design + professional schematics
- Firmware development (ESP-IDF / Arduino framework)
- PCB design (Gerber files)
- Assembly + bench testing
- Testing video/demo of the working prototype
This gig is only for ESP32-based IoT / embedded systems (WiFi, BLE, sensor applications, automation, smart devices, etc.).
Send me a short description of your idea, and I'll respond with a quick breakdown and timeline.

FAQ
Can you sign an NDA?
Absolutely. If you need an NDA before sharing your idea, just send it and I’ll sign.
Do I need to provide a detailed technical specification?
Not at all — a simple description of what you want the ESP32 to do is enough (e.g. “read temperature and send data over WiFi”). I can help define the technical requirements.
Which frameworks do you use for firmware?
I typically use either ESP-IDF or Arduino framework depending on the complexity and performance needs of your project.
Will I get the source files?
Yes — all packages include schematic files, firmware source code.
Can you also ship the assembled prototype?
Yes — shipping of the assembled prototype is included in the extra (shipping cost may be extra depending on your location).
What happens if my idea is not technically possible?
If it’s not feasible (very rare), I’ll clearly explain why and suggest an alternative approach — before starting the order.

She did a great job. From the beginning, she was willing to understand the project, she understood why some components had to be changed, and she made the adjustments correctly. She also sent me a 3D video of the final product. Very professional in her work.
