Hire the Best TouchPoint Software Specialists

Hi, I'm Landon 👋 I help inventors, startups, and businesses turn ideas into real products through CAD design, prototyping, manufacturing, electronics integration, and 3D printing. Unlike many CAD freelancers, my background comes from years of hands-on work in manufacturing, CNC machining, industrial electronics repair, fabrication, and commercial refrigeration systems. That experience allows me to design products that not only look good on screen but are practical to build, assemble, test, and manufacture in the real world. Whether you're starting with a sketch, refining an existing concept, or developing a product for production, I can help with: • Product Design & Development • Shapr3D CAD Modeling & Training • Functional Prototypes • 3D Printing & Additive Manufacturing • Electronics Enclosures & Integrated Assemblies • Mechanical Design & Custom Mechanisms • Manufacturing-Ready Files (STEP, STL, DXF) • Design for Manufacturing (DFM) • Technical Renderings & Presentations My projects have included consumer products, illuminated signs, industrial equipment, drone components, automotive accessories, custom electronics, tooling, and production-ready assemblies. I maintain in-house prototyping equipment and regularly validate designs through real-world manufacturing and testing. This helps catch problems early, reduce development time, and create designs that are ready for the next step. Why work with me? ✅ Real-world manufacturing and fabrication experience ✅ Electronics, mechanical, and product development knowledge ✅ Hands-on prototyping and testing capability ✅ Fast communication and practical problem-solving ✅ Top-rated freelancer with a 100% Job Success Score If you need more than just CAD work and want someone who understands how products are actually built, I'd be happy to help bring your idea to life.

I am a senior electronics and embedded systems engineer with 47 years of experience in hardware design, firmware development, PCB layout, debugging, testing, and product development. I help clients turn electronic product ideas, prototypes, and hand-wired circuits into working embedded systems and manufacturable PCB designs. Typical projects I can help with include: * ESP32 and STM32 / STMicroelectronics MCU-based products * Power conversion and low-power battery-powered product design * Custom wireless and RF communications, including LoRa and ESP-NOW peer-to-peer networking * Circuit design and component selection for manufacturing * Schematic entry and multi-layer PCB design. * Ordering fabs and coordinating assembled boards. * C/C++ firmware for sensors, displays, audio, wireless, and control systems * Embedded graphics and touchscreen user interfaces using LVGL * Digital audio filtering, FFT spectrum analysis, and voice activity detection * Cloud API integration for speech-to-text, text-to-speech, and language translation * Embedded bus and peripheral interfaces: I2C, SPI, I2S, UART, RS-485, CAN, and SD/MMC * Prototype debugging and board bring-up * Converting breadboard prototypes into clean PCB designs * Design reviews before manufacturing * Analog and digital circuit troubleshooting * Production-oriented improvements for reliability and manufacturability I have founded and managed engineering companies and consulting firms, led technical teams, and helped bring electronic products from initial concept through prototype, testing, manufacturing, and production. For clients, this means fewer design mistakes, faster debugging, lower development risk, and a clearer path from concept to a working, manufacturable product.

I build things that exist in the physical world — embedded systems, robotic mechanisms, IoT devices, and hardware prototypes that go from sketch to functional product. With hands-on experience across ESP32, Raspberry Pi, Arduino, STM32, and RTOS-based systems, I work the full hardware stack: firmware, sensor integration, CAD enclosure design in Fusion 360, FDM 3D printing, and PCB layout. I've shipped across domains — rehabilitation robotics, predictive maintenance, food safety sensing, animatronics, and industrial IoT. Currently a Product R&D Intern at Xibotix (building rehab devices and animatronic systems) and previously at Dotworld Technologies, where I delivered real-time actuator control systems end-to-end — from firmware to deployment. I work best with startups that have an idea but need someone who can build it. I don't just write code — I think about the enclosure, the power architecture, the sensor placement, and what failure looks like at 3 AM. That's the difference between a demo and a product.
