Hire the Best Electronic Designers
in India

Career Objective: Innovative thinker and well-established electronic engineer with expertise in all areas of electronics design, Embedded design, development, programming, and full-life cycle product Engineering. I am willing to work for an organization that would utilize my skills and offers me an opportunity to learn and grow with it. Skill set includes multi-processor troubleshooting and transitioning new products into production. Dependable self starter with the ability to work well with others.

I am a CAD designer with skills in 3D design and 3D printing, working with industries like engineering and manufacturing. I use top software like SolidWorks, Fusion 360, Blender, ZBrush and KeyShot to create accurate and high-quality designs. 🔹 3D Printing Expert I create ready-to-print 3D models with the accurate size and settings to ensure smooth printing. Whether you need functional parts, prototypes or artistic designs, I make sure they print well on FDM and SLA/Resin printers. 💡 If your model is too big for your printer, I can split it into smaller parts for easy assembly while keeping it strong. I will also adjust the design to fit your printer’s bed size (for example, 220 mm X 220 mm X 250 mm), so it prints efficiently with fewer supports. What I Can Do for You: ✔ 3D Printing & Prototyping – Ready-to-print models with the best settings ✔ Product Development – Development of product as per Inputs given. ✔ 2D Design & Drafting – Clear technical drawings and blueprints ✔ 3D Modeling & Rendering – Realistic 3D visuals for products and concepts ✔ CAD Conversion – Turning sketches, PDFs, and old files into digital designs ✔ 3D Texturing – Adding details to make 3D models look more realistic Let’s work together to bring your ideas to life with expert 3D design and printing solutions! Message me, and let’s talk about your project.

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.
