Hire the Best Computer Hardware Designers
in India

I am an electronics engineer with a decade of experience in schematic design, PCB layout, and firmware development. After founding a successful tech startup in 2010, I am now seeking to expand my reach through online platforms. My company specializes in the design and development of customized consumer and industrial electronics projects, offering state-of-the-art solutions and dedicated computer systems. Over the years, we have successfully designed various systems, including data loggers, data monitors, data acquisition systems, data processors, process controllers, and IoT solutions tailored to our clients' specific needs. Our expertise spans microcontrollers, microprocessors, FPGAs, SoCs, and System-on-Modules (SoMs). We are also proficient in wireless technologies such as XBee, BLE 4.0, BLE 5.0, GSM, and LoRa. Services we offer: 1. Component Engineering 2. Schematics and PCB design 3. Firmware development 4. Prototypes and Mass production 5. Vendor Co-ordination Deliverables we provide include: 1. PDF Documentation: Schematics, PCB artwork, and 3D views of the PCB. 2. Source Files: Schematics and PCB files in Altium format. 3. 3D STEP File: A detailed representation of the PCB. 4. Gerber Files: For manufacturing. 5. NC Drill Files: For precise drilling specifications. 6. Bill of Materials (BOM): Compiled from verified vendors and suppliers such as Mouser, Digi-Key, and JLC, ensuring reliability and consistency over time. 7. Firmware/Software: Including codes and sketches tailored to your specifications. 8. Prototypes and Mass Production: Comprehensive support from concept to production. We prioritize compatibility with leading vendors like Mouser, Digi-Key, LCSC, and JLCPCB in our BOMs, facilitating a comparative analysis of available components and expediting the prototyping and mass production processes. Additionally, we ensure that selected components are stable and widely available, mitigating concerns about obsolescence or stock shortages. I look forward to the opportunity to collaborate and contribute to your project’s success.

I’m Avi Gupta, an electronics and PCB design expert with 11+ years of experience and 500+ boards designed for IoT, industrial, medical and consumer products. I help startups and product companies turn ideas into production-ready hardware using Altium Designer and other industry tools. ✅What you actually get when you work with me • Boards that are designed to pass EMI/EMC, not just “hope for the best” • Architecture and layout decisions that reduce respins and save months • Clear, production-ready documentation your manufacturer will thank you for ✅I’m most useful to you if: • You have a concept or early prototype (ESP32, STM32, or similar) and need it turned into a robust, production-ready Altium design. • You already have a board that “sort of” works and you’re worried about noise, reliability, thermal issues, or compliance. • You need an experienced hardware mind to own the electronics while your internal team focuses on firmware, apps, or business. ✅What I can help you with 1. New product hardware design (concept to production-ready PCB) • Architecture and block diagrams for your electronics (MCU, power, interfaces, connectivity) • Schematic design and capture in Altium Designer (or KiCad/Eagle on request) • Multilayer PCB layout with controlled impedance, length matching, and proper grounding • Design for manufacturability (DFM) so your CM can build and test boards smoothly 2. PCB review, cost-down and reliability upgrade Already have a design? I can: • Review your schematic and PCB layout for signal integrity, power integrity, and EMI/EMC risks • Reduce BOM and PCB cost (alternative components, better stack-up, optimized routing) • Improve thermal behavior and reliability for 24/7 operation in real environments • Help you move from “prototype that works on the bench” to “design that works in production” 3. Compliance-conscious, production-focused design • Design practices aligned with EMI/EMC, CE, UL and CISPR requirements • Grounding, filtering, shielding and layout strategies to avoid surprises in the test lab • Clean documentation: schematics, PCB files, Gerbers, fabrication/assembly outputs, PDFs, BOMs ✅Recent project highlights • Designed an ESP32-based LoRa IoT sensor node with RS485/Modbus interface for industrial monitoring. Created a 4-layer Altium PCB optimized for low power, robust EMC behavior, and easy enclosure integration. • Developed an STM32-based industrial controller board with isolated digital inputs/outputs, 24 V power domains, and RS485/CAN communication. The hardware was taken from concept to tested prototype and prepared for volume manufacturing. • Reviewed and cost-optimized an existing ESP32 control board, replacing hard-to-source parts, simplifying the power stage, and reducing BOM cost by ~25% while improving thermal margins and layout quality. • Designed a Raspberry Pi-compatible expansion HAT with LoRa communication, environmental sensing, relay output and RGB indication. Delivered complete Altium design, manufacturing files, and test guidance for small-batch production. • Created a high-voltage/power PCB with isolated gate drivers, current sensing, and careful creepage/clearance management. Layout was done with EMI/EMC and safety in mind to support future certification. ✅Tools, technologies and platforms • Primary CAD: Altium Designer (main tool for professional work) • Also experienced with: KiCad, Eagle, EasyEDA, Proteus • MCUs: ESP32, ESP8266, STM32, NXP, TI and similar 32-bit controllers • Interfaces: RS485, Modbus, CAN, Ethernet, SPI, I2C, UART, USB • Wireless: Wi-Fi, BLE, LoRa (module-based designs) • Applications: IoT devices, industrial controllers, sensor boards, data loggers, power electronics, battery-powered products ✅How I work • Hardware-first mindset: I focus on solid electronics architecture and PCB design; I can support basic firmware bring-up and collaborate closely with your firmware/software team. • Clear communication: upfront questions, regular updates, and intermediate design reviews so there are no surprises. • Production thinking: I design as if your board will go to manufacturing – even if you’re only building 5–10 units today. If you need a reliable hardware partner to design, review or optimize your PCB for a real product (not just a one-off hobby build), send me a message with a short description of your project, current status, and timeline. Let’s see how we can get your hardware ready for the field.
