Architecting scalable systems from infrastructure to intelligence. Specialized in end-to-end full-stack development and automating complex digital solutions through the lens of an AI Engineer
Building Robust Systems,
Exploring the Future of AI.
Hi, I'm Herna Rusdiyana, a Software Engineer dedicated to building systems that don't just work, they scale. I've navigated the full lifecycle of software development, from designing intuitive user interfaces with React/Next.js to architecting robust backend systems using node.js and Python (Django/FastAPI).
I don't stop at web applications. I'm deeply invested in the "unseen" parts of technology, automation systems and infrastructure that keep businesses running smoothly. This passion for efficiency led me to found Kloosr, an IT System Solution provider focused on delivering streamlined digital ecosystems.
Currently, I am expanding my horizon into AI Engineering. My goal is to bridge the gap between traditional software and machine learning, creating "thinking" applications that solve complex problems with data-driven insights.
When I'm away from the terminal, I'm likely exploring new landscapes. As a tech-travel entusiast, I believe that seeing the world gives me a freash perspective on how to build for it.
