01. Background

About Me

Hello! I'm Husni, a developer who enjoys building engaging products and bringing complex ideas to life. My journey in technology started in 2020 building membership applications, which quickly evolved into a passion for full-stack development and complex system architectures.

Fast-forward to today, and my focus has heavily expanded into building robust Fintech systems (like UBPAY Syariah) and tackling intricate Hardware & IoT challenges (such as the SPARKO Smart Parking System and Autonomous Robotics).

I thrive at the intersection of software and hardware. Whether I'm designing a silicone load cell using COMSOL, wiring an Arduino-based security system, or shipping a React-based e-learning platform, my goal is always to deliver scalable, production-ready solutions.

"When I'm not coding or tinkering with microcontrollers, I'm usually exploring new technologies to integrate into my next big project."
