About me
Hi, I'm Rayyan, an Electrical Engineering student at the University of Oklahoma with hands-on experience in embedded systems, IoT and robotics. I was an international finalist at Regeneron ISEF 2024 and the World Robot Olympiad 2023, and I'm the lead developer of Aid Nexus Link, an offline-first crisis response app. I help clients build and fix Arduino and ESP32 projects, IoT prototypes, circuit and PCB designs, and websites or web apps. I also offer Arabic to English translation and math and physics tutoring. Clear communication, clean documented work, on-time delivery.
