Computer Engineering Graduate & Embedded Systems Enthusiast

Building the future where hardware meets software. Recent UC Irvine graduate, passionate about low-level programming, algorithm design, and creating things that fly.

What I'm Passionate About

Embedded Systems

Deep dive into microcontrollers, RTOS, and hardware-software integration. From Arduino to ARM Cortex, I love working at the intersection of hardware and code.

Algorithm Design

Fascinated by the theoretical foundations of computer science. Analyzing complexity, designing efficient solutions, and solving challenging problems on LeetCode.

FPV Drones

Building and flying custom FPV racing drones. From flight controllers to video transmission, combining my engineering skills with an adrenaline-fueled hobby.

Machine Learning

Exploring the frontiers of AI and neural networks. From computer vision to deep learning, always eager to learn and implement cutting-edge techniques.

Hardware Design

PCB design, circuit analysis, and digital logic. Understanding how electrons move to make computation possible, one transistor at a time.

Innovation

Always looking for ways to push boundaries and create something new. Whether it's optimizing code or building the next cool gadget.
