What I'm looking for

I'm looking to build useful, intuitive, and visually engaging web experiences where I can turn complex ideas into simple solutions and keep learning.

I built HELPIT, a mental health social network focused on emotional wellbeing, during SENA's Hackathon 4 Future. The project led to an invitation from Nestlé to present how technology can serve social purpose to young leaders.

I've also developed a SaaS MVP for personal coaches across the frontend, backend, and database, and created projects including Liftio, a personalized fitness coaching web app, and KAT, an embedded terminal built with Electron and JavaScript. I enjoy turning complex ideas into simple, visually engaging solutions through clean code, good design, and constant learning.
