About
Bridging hardware and software
I’m an engineer who builds systems that extend beyond the screen. My expertise lies in connecting physical devices to digital interfaces—whether it’s writing firmware for a robotic arm, building a scalable IoT dashboard, or crafting a native Android app for millions of users.
I don't just write code; I design complete product ecosystems. From optimizing memory on an ESP32 to architecting a Next.js frontend, I love the challenge of making complex systems feel simple, responsive, and human.
Current Focus
Edge AI & Autonomous Systems
Exploring edge AI integration on low-power devices and building autonomous systems that learn from their environment.
Currently building: Custom smart-home voice node
