Bhavin V.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I help companies turn electronics ideas into real, production-ready products. I am an Embedded Systems Engineer with 10+ years of experience designing hardware, developing firmware, and building connected IoT and Edge AI devices from concept to mass production. I have worked with startups, research labs, and global organizations, including collaborations with Fortune 500 companies, The University of Bristol, and PGA of America. I don’t just build circuits I build complete products that are reliable, scalable, and ready for manufacturing. What I do end-to-end • System architecture and product definition • PCB design and hardware engineering • Firmware development and optimization • Edge AI integration (TinyML, on-device inference) • Wireless connectivity and IoT cloud integration • Mechanical design (enclosure + DFM-ready CAD) • Prototype development and production support I regularly take products from idea to prototype to production-ready hardware. --- Core expertise Embedded hardware development • ESP32 • Nordic (nRF51, nRF52, nRF91) • STM32, STM8 • Raspberry Pi platforms • NXP, Snapdragon, BeagleBone • NVIDIA Jetson AGX Orin • Google Coral Edge TPU • Axelera Metis AI Platform • EdgeCortix SAKURA • ARM Cortex controllers • Texas Instruments MSP and CC series • Atmel AVR and Arduino I design reliable embedded systems used in IoT devices, industrial equipment, wireless products, and research hardware. --- PCB design and hardware engineering Tools • Altium Designer • KiCad • EagleCAD • OrCAD Services • Schematic design • Multilayer PCB layout • High-speed PCB design • RF and wireless board design • Design for manufacturing (DFM, DFA) • BOM optimization and cost reduction • Production-ready manufacturing files --- Firmware development • Embedded C and C++ • FreeRTOS • Embedded Linux • Driver and low-level development • Low-power firmware optimization --- Edge AI • TinyML and on-device AI models • Sensor data processing and inference at the edge • ESP32 / ARM-based AI deployment • Reducing cloud dependency with real-time intelligence • AI-enabled IoT product design --- Communication and connectivity • Bluetooth, BLE, BLE 5 • WiFi • LoRa, LoRaWAN • NB-IoT • Thread, Zigbee • NFC, RFID • CAN • UART, SPI, I2C, USB, Ethernet Cloud and protocols • MQTT • HTTP • AWS IoT, AWS Lambda and cloud integration --- Mechanical design • Enclosure design for embedded products • 3D CAD modeling (production-ready) • Thermal and space optimization • Design aligned with PCB and manufacturing constraints • Support for injection molding and prototyping --- IoT product experience • EdgeAI Device for ATM • High-Speed Autonomous Surveillance Drone (350–400 km/h) • AI Personal Assistant • Smart Home Automation Systems • Wireless IoT Sensors • Industrial Monitoring Systems • GPS and Tracking Devices • Medical and Research Hardware • Automation Controllers • Cloud-connected Embedded Devices --- What I deliver • Production-ready PCB designs • Stable, optimized firmware • Functional hardware prototypes • Edge AI-enabled intelligent devices • Hardware debugging and performance optimization • Complete manufacturing support and documentation --- Client feedback “Bhavin is such a fantastic developer to work with. He was professional and handled all modifications seamlessly. He also immersed himself in the problem and provided unique solutions to the hardware and software challenges.” “I would happily employ Bhavin again. He is extremely efficient, works very fast, and communicates very well. The product was delivered on time and worked perfectly.” --- If you are building a new hardware product, IoT device, or Edge AI system, feel free to reach out to discuss your project.
