About

I'm Joshua Palti Sinaga, an Informatics Engineering student at Sumatra Institute of Technology (ITERA) and a full-stack web & mobile developer from Indonesia.

I love solving problems around me, turning challenges into opportunities for innovation. I focus on creating applications that blend functionality with intuitive design, ensuring a seamless user experience. As a Nuxt.js and Next.js developer, I build performant web applications, while also developing cross-platform mobile apps using technologies like Capacitor and Flutter.

Beyond full-stack development, I'm passionate about exploring AI and IoT projects, integrating cutting-edge technologies to build innovative solutions. I work with TypeScript, Golang, Python, MongoDB, PocketBase, and Firebase to create end-to-end applications that make a real impact.

Began my focus in programming at 16 years old, I had the honor of participating in and winning 1st place at the LKS North Sumatera competition 🏆 — a provincial-level vocational skills competition.

Currently, I am studying Informatics Engineering at the Sumatra Institute of Technology (ITERA), where I continuously expand my knowledge in software engineering, database design, and emerging technologies.
