I am a passionate Frontend and Mobile Developer currently pursuing an Informatics degree at Politeknik Elektronika Negeri Surabaya (PENS), based in Surabaya, Indonesia. I focus on building fast, clean, and functional web and mobile applications—ranging from modern interface designs to intelligent artificial intelligence integrations.
- Scalability Building systems that scale. I focus on clean architecture, modular code, and scalable database schemas that remain robust across all production levels.
- Intelligence Integrating AI to provide real value. I focus on transforming machine learning models into automated functionality, bridging user experience with intelligent automation.
- Precision The beauty of a system lies in its details—from pixel-perfect, interactive user interfaces to fast, lightweight, and optimal application performance.
