I am the founder of The-DIY-Life, an R&D company in the Field of Internet of Things. I am a Leader of a professional developers Team, working on the field of IoT and Embedded Systems. Our Company has several "modules on shelf" to reuse on our projects. we care more about the quality of the project we work on than the quantity of the projects. so we invest time on documentation and version control system using Git. We use freelancer.com as a business platform to know more clients, and feature our work. Despite we support the opensource software, and we have several opensource work on our page on Github, we also respect the privacy of our clients work.

Veteran, expert system developer in multiple domains including web apps, iOS and Android, embedded microprocessor systems, High-Performance Computing with NVidia GPUs (CUDA), graphics, database, and telcommunication systems. Large scale projects from concept to development to marketing no problem. Longtime U.S. expat in Japan, so bi-lingual in English & Japanese. I am fairly new to Freelancer (but not at development), so I only have a few Freelancer "references" and "credits" so far. Personal references and examples of various projects, both small and large, will gladly be provided upon request.

Hi, I am Jamal and I have been doing Embedded Systems (Hardware and Software) development for the last 7 years, I have completed 350+ projects related to almost all electronics categories i.e. IOT, Power electronics, Highspeed, RF, HDI, etc. covering both Hardware and Software. My main areas of focus are Motherboards, SOMs for Microprocessors and FPGAs, Carrier Boards, and HDI boards mainly High-speed products. I have designed and developed several projects for IMX6, IMX8, RK5528, Xilinx Zynq-based SOMs, PCDU and DAU units for LEO earth Sattelites, Carrier boards for CM3, CM4, CN9130, Nvidea Jetson Nano boards, Ethernet and POE products (POE++, POE PD, POE PSE etc). I have worked on following high-speed interfaces - DDR3 and DDR4 - PCIe - Ethernet - HDMI - LVDS - MIL1553 - Ethernet - USB Apart from that, other interfaces include CAN, SPI, I2C, etc I have complete professional expertise in Altium (Licensed), Eagle (Licensed), KiCAD, OrCAD/Allegro, Solidworks, Fusion360(licensed), Thanks Jamal

Stop paying for PCBs that “work on the bench” and die in the field. I’m Avi Gupta, an electronics and PCB design specialist with 11+ years of experience and 500+ boards shipped for IoT, industrial, medical, and consumer products. I turn your idea or rough prototype into production-ready hardware using Altium Designer and other industry tools. ✅ What you really get working with me • Designs aimed to pass EMI/EMC and safety – not just “it seems fine” • Architecture and layout that reduce respins, delays, and surprise costs • Clean, production-ready documentation your manufacturer can build from ✅ I’m a good fit if you: • Have an ESP32/STM32 (or similar) prototype and need a robust Altium design for production • Already have a board but are worried about noise, reliability, thermal issues, or compliance • Want a senior hardware mind owning electronics while your team focuses on firmware/apps ✅ How I can help 1. New product hardware design • System architecture and block diagrams (MCU, power, IO, connectivity) • Schematics in Altium (KiCad/Eagle possible on request) • Multilayer PCB layout with controlled impedance, length matching, solid grounding • DFM-focused layout so CMs can assemble and test smoothly 2. PCB review, cost-down & reliability upgrade • Schematic/layout review for SI/PI, EMI/EMC, grounding, protections • BOM and PCB cost reduction (alt parts, stack-up, routing optimizations) • Better thermal behavior and reliability for 24/7 environments • Moving you from “lab-only prototype” to “production-grade design” 3. Compliance-conscious, production-focused design • Design practices aligned with CE, UL, CISPR and EMI/EMC expectations • Grounding, filtering, shielding, creepage/clearance planning • Full outputs: schematics, PCB files, Gerbers, fab/assembly files, BOMs, PDFs ✅ Sample project types • ESP32-based LoRa/RS485 industrial IoT nodes • STM32 industrial controllers with isolated IO, 24 V domains, RS485/CAN • Raspberry Pi HATs with sensors, relays, RGB indicators and field wiring • High-voltage / high-power PCBs with isolated gate drivers and current sensing • Cost-optimized redesigns of existing ESP32/STM32 boards ✅ Tools & technologies Altium Designer (primary), plus KiCad, Eagle, EasyEDA, Proteus MCUs: ESP32/ESP8266, STM32, NXP, TI Interfaces: RS485, Modbus, CAN, Ethernet, SPI, I²C, UART, USB Wireless: Wi-Fi, BLE, LoRa (modules) Applications: IoT, industrial control, sensing, data logging, power and battery-powered products ✅ How I work • Hardware-first: solid architecture and PCB design, with basic firmware bring-up support • Clear communication: upfront questions, regular check-ins, review milestones • Production mindset: I design as if your board will be built at scale, even for 5–10 units If you need a reliable hardware partner for a real product (not a hobby build), message me with your idea, current status, and target timeline. Let’s make your hardware ready for the field.
