What I'm looking for

I’m looking for a role where I can build secure, scalable full-stack systems and ship real-world IoT/robotics integrations, while growing with strong engineering mentorship and modern tooling.

I’m an enthusiastic Information Technology undergraduate building scalable web apps and integrating hardware–software solutions across IoT and robotics. I focus on modern software engineering and secure coding, aiming to turn real-world innovation into reliable products.

Through projects, I’ve developed full-stack applications and platforms—ranging from biometric and role-based access systems to multi-tenant architecture and decentralized governance features. I also enjoy autonomous robotics work, using simulation and pathfinding algorithms to deliver accurate behavior under real constraints.
