Custom PCB Design
Production-ready circuit boards for embedded systems and product prototypes.
Portfolio & Case Studies
Documented engineering work, from a full problem-to-solution case study through representative PCB, wireless and automation hardware examples.
Featured Case Study
CoachLink: ESP32 LoRa Communication System
ESP32LoRaCustom PCBOLED DisplayMobile App
Problem: Wi-Fi range is short, cellular networks need a SIM card, and internet-based systems aren't always available in the field — all of which make remote messaging expensive and unreliable in industrial and outdoor deployments.
Solution: A mobile app communicates with an ESP32-based LoRa gateway, which relays messages to a remote, battery-powered LoRa node over a long-range wireless link — no internet or SIM card required.
Hardware & firmware: Custom PCB design for the gateway and node, OLED display support on the node, and ESP32 firmware handling LoRa communication, message routing and battery-powered operation.
