@iamhamzazaki

As a seasoned Embedded Systems Engineer, who has spent over 7 years in designing and building complicated hardware systems, including medical and consumer devices, I am both qualified and eager to take charge of this project and ensure your product is developed to its fullest potential. Adept at reading AutoCAD files, I can seamlessly put together the 2-part SLS Nylon housing for Spira, complete with bayonet twist-lock TPU mouthpiece and validate functionality by establishing a secure USB/JTAG connection. My experience with Li-Ion batteries and charging circuits also guarantees fuss-free power-up for your device. Having worked extensively with JLCPCB and PCBWay, I'm confident in fabricating PCBs per your provided schematic using high-quality parts from your BOM - like the Honeywell differential pressure sensor. Additionally, having had experience in firmware flashing similar devices from ESP32 or STM32 microcontrollers via USB/JTAG mode, I guarantee that the flashing step will be executed fluently, confirmed through OLED display outputs and BLE broadcasting. The success of this spirometer prototype will be a testament to the quality workmanship I pour into each project.

Hi there! I can deliver a reliable biomedical hardware solution with sensor integration, embedded system design, and precise data acquisition—ensuring accurate performance, safety, and compliance-ready development for medical-grade applications. Questions ? What type of device are you developing (wearable, diagnostic, or monitoring)? ? Do you need full hardware + firmware + PCB design or only specific modules? ? Any regulatory standards to follow (FDA, CE, ISO)? Don't pay a single penny until you are happy with the job I look forward to your response and thank you for your consideration. Warm regards, The Blend Nation.

@tetianam8

⭐⭐⭐⭐⭐ I’ve reviewed your scope carefully—this is a precision assembly + validation build for a medical-grade prototype, and the critical factors are clean assembly, sensor integrity, and reliable firmware flashing/verification. I’ve built and delivered compact embedded devices (ESP32/STM32, BLE, sensors, OLEDs) and handled full workflows from PCB fabrication (JLCPCB) to enclosure integration, so this aligns well. How I’ll execute: Assembly & Fabrication • Order & inspect PCB (5-layer) + components • Precision SMT + through-hole assembly (ESD-safe) • SLS enclosure print + post-processing for clean fit • Careful integration of airflow channel + sensor chamber (no leakage) Firmware & Bring-up • Flash via USB/JTAG per your instructions • Verify: OLED output, BLE advertising, sensor readings • Basic calibration sanity check (signal response consistency) Quality focus (important for clinical path): • Clean solder joints, strain relief, secure battery integration • Airflow path integrity (no obstruction or misalignment) • Full functional check before shipment Answers: Yes—handheld IoT/medical-adjacent sensor devices (can share samples privately) Yes, fully comfortable with AutoCAD + USB/JTAG flashing Estimated total: $700–$1,300 (depends on fabrication choices) US-based; typical turnaround 2–3 weeks Quick question: do you require any initial airflow calibration jig, or just functional verification at this stage?

@electronicsdone

Best Biomedical Prototype Build Engineer for Functional Device Assembly! ⭐⭐⭐⭐⭐ Dear Client, This project is really about disciplined prototype execution. Since your firmware, housing files, BOM, and specs are already prepared, the value now is in assembling everything cleanly, flashing it correctly, and delivering one working prototype that behaves as expected without unnecessary redesign or improvisation. I can help by: 1. fabricating and assembling the electronics and mechanical stack according to your provided files and tolerances 2. flashing the provided firmware and verifying OLED output, BLE broadcast, and airflow sensor response 3. documenting progress with photos/videos and delivering a prototype that is ready for your functional review This keeps the work focused on reliable build execution and validation, which is exactly what matters at this stage. Two quick questions: 1. Will all fabrication files and the final PCB data be provided in production-ready form, or do you expect any pre-build manufacturability review? 2. Do you want the basic functional check documented as a short acceptance video before shipment? If you message me, I can outline the cleanest build sequence and milestone flow for the prototype. Best regards, Prat PCB Must Innovations
