I am seeking a US-based hardware developer or electronics technician to assemble two physical prototypes of an RF-based proximity system. I have already developed the full source code and circuit schematics; however, due to a physical disability, I require a partner to handle the soldering, wiring, and physical housing of the components. Technical Requirements The project consists of two separate units: a Transmitter and a Receiver. Microcontrollers: Program and integrate 2x Arduino boards (provided/specified in schematics). Connectivity: Configure RF modules for proximity detection. Power: Integrate rechargeable battery systems (Li-Po or similar) with charging ports for both units. Assembly: Solder all components according to provided schematics. Enclosure: Mount components into two separate, durable housings (3D printed or off-the-shelf enclosures). Scope of Work Hardware Procurement/Review: Review my provided schematics and ensure all parts are compatible. Assembly & Soldering: Clean, professional wiring and secure mounting of components. Firmware Upload: Upload my existing code to the boards and verify the RF handshake/signal trigger. Final Delivery: Ship two fully assembled, "plug-and-play" units that are ready to use out of the box. Logistics & Location US-BASED ONLY: Due to shipping regulations regarding lithium batteries and electronic components, I am only accepting bids from freelancers located within the United States. Communication: Must be willing to provide a brief video demonstration of the working units before shipping. The agreed-upon price must include shipping to Oregon.

I am a skilled and reliable Embedded Systems Engineer with over 6 years of hands-on experience in Arduino, ESP32/ESP8266, and microcontroller-based development. I specialize in designing efficient, stable, and scalable embedded solutions, turning ideas into fully functional hardware-software systems. I have a strong background in electronics, sensors, communication protocols (UART, I2C, SPI, MQTT, WiFi, BLE), and real-time embedded systems. My development approach focuses on clean, well-structured, and well-documented firmware, ensuring long-term reliability and easy maintenance. I also provide thorough testing, debugging, and performance optimization, including power efficiency improvements where required. I am a detail-oriented engineer with strong problem-solving skills and extensive experience in hardware debugging and firmware optimization. Beyond technical expertise, I value clear communication, meeting deadlines, and maintaining high client satisfaction. I work closely with clients to fully understand project requirements and deliver high-quality results. Pricing is flexible and can be discussed based on project scope and complexity. I am open to both short-term and long-term projects. Let’s work together to build a professional, reliable, and efficient embedded system for your needs.

Hello, I’ve reviewed your plan for assembling two RF-based proximity units and I’m confident I can handle the soldering, wiring, and durable enclosures while integrating your two Arduino boards with care. I’ll verify schematic compatibility, select reliable connectors, and wire the Li-Po battery charging setup to ensure a clean, safe power path. I’ll upload your existing firmware to verify the RF handshake and trigger logic on both the Transmitter and Receiver, then assemble two plug‑and‑play housings (3D-printed or off‑the‑shelf) with tidy cable routing and strain relief. I’ll document wiring diagrams and provide a brief video demo of both units before shipment, and I will ship to Oregon as requested. What is the exact enclosure type and required IP rating you prefer for the two units, and do you have preferred RF modules for compatibility with your schematics? Best regards, Marko Aleksic
