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, a service that designs technology strategies, system integration, business process automation, and operational software development for companies (especially in the manufacturing industry).
I have deep expertise as a Manufacturing Software Developer Engineer. I specialize in building and integrating digital solutions for production environments, ranging from automated shop-floor systems to real-time data analytics that optimize manufacturing processes.
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. a service that design
