Send a sketch, reference photo, STL, or written spec. I model or prepare it in CAD (Autodesk Inventor / OpenSCAD), print it on a Bambu Lab X2D (multi-color, 256mm build volume), and ship the physical part to you. You get photo/video proof of the finished print before it ships. Included: print-ready, support-free, DFM-correct design; single material/color (PLA or PETG); part up to ~200×200×200mm; international shipping. Multi-color, multi-part assemblies, or engineering-grade materials quoted on request. Booking slot = project kickoff. Typical lead time to shipped part: 3 working days. Definition of done: a physical part in your hands matching the agreed spec, with visual proof.
I write and debug firmware for ESP32 and Arduino. Addressable RGB/RGBW LED control (FastLED), sensor integration, WiFi web controllers (AP + WebSocket), and IoT over Matter/Thread/BLE. I can also design the PCB in KiCad, solder, and bring the hardware up on a real bench. You receive: clean commented source code, a wiring schematic, and a short demo video of it running on real hardware. Remote-friendly. This fixed package covers one defined small firmware module (~4 hours of work). Larger projects or full PCB design quoted separately. Definition of done: working, documented firmware demonstrated on physical hardware, plus source files.
I am a versatile hardware and embedded systems engineer with a strong passion for bringing innovative physical products to life. My expertise spans the entire development lifecycle, from initial concept and CAD modeling using tools like Autodesk Inventor and OpenSCAD, through rapid prototyping with FDM 3D printing, to the design and assembly of complex electronics. I'm proficient in PCB design with KiCad and hands-on soldering, enabling me to build and test robust hardware solutions. My embedded firmware skills cover microcontroller programming, particularly with Arduino and ESP32, and I have experience implementing advanced LED systems and integrating IoT technologies like BLE, Matter, and Thread for smart and connected devices. I am adept at reverse engineering, thorough hardware testing, and creating detailed technical documentation, ensuring products are not only functional but also optimized for manufacturing. I thrive on solving complex technical challenges and transforming ideas into tangible, high-quality products.
