Gaurav J.

Greetings, Hope you are doing well. Are you looking to turn your electronic idea into a reliable, compact, and production-ready PCB? You’re in the right place. I help startups, product teams, and businesses design robust hardware that works in the real world — not just on paper. Why Choose Me? With 4+ years of hands-on experience in PCB design, firmware development, and prototyping, I’ve successfully delivered consumer, industrial, and IoT hardware projects from concept to working prototype and manufacturing. I understand both engineering fundamentals and production constraints, which helps reduce risk, cost, and redesign cycles. My core expertise includes: # PCB Design Tools EasyEDA/PRO, KiCad, DipTrace # Microcontrollers & Platforms ESP32 (S3, C3, C6), STM32, ATmega family & nRF series # Firmware & Programming Embedded C/C++, ESP-IDF, Arduino, HAL-based development # Low-Power & Compact Designs Battery-operated, wearable, and ultra-small form-factor PCBs # Wireless & IoT Systems Wi-Fi, BLE, GSM / LTE / 4G # Interfaces & Sensors I²C, UART, USART, SPI, RS485, RS232, CAN # Power Electronics Buck converters, LDOs, battery charging & protection, reverse-polarity and ESD protection What I Offer # End-to-End Hardware Development Schematic design, component selection, PCB layout, and design optimization # Firmware Development & Programming Peripheral drivers, sensor interfacing, communication stacks, power optimization # Full Prototype Support Board bring-up, debugging assistance, validation, and iteration support # Manufacturing-Ready Designs DFM/DFA-optimized layouts compatible with JLCPCB / PCBWay # Production Deliverables Gerbers, BOM (LCSC-preferred parts), Pick-and-Place, STEP files # Reliable Power & Protection Design Low-noise rails, battery optimization, and user-proof protection circuits Why Clients Love Working With Me I deliver clean, documented, and review-ready designs I support projects beyond just files — up to working prototypes I respect timelines and budgets I communicate clearly and proactively I focus on practical, manufacturable solutions If you’re looking for someone who can design the PCB, write the firmware, and support the prototype until it works, I’d be glad to collaborate. Let’s connect and build something reliable together.
