Hire the Best Analog Electronics Specialists
in India

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.
