Naufal Ichsan
Software & Cloud Engineer
Specializing in scalable backend systems, distributed architectures, cloud-native solutions, and AI engineering. A Computer Science graduate from Universitas Indonesia, I focus on building reliable, secure, high-performance systems, and integrating data-driven engineering and AI techniques to solve complex architectural challenges. Driven by continuous learning and adaptability in fast-paced environments.
About Me
Building scalable systems across software, cloud, and AI.
I'm a Computer Science graduate from the University of Indonesia and a Software and Cloud Engineer focused on backend development, distributed systems, and cloud infrastructure, with experience in data and AI engineering. I've worked with microservices, event-driven architectures, scalable data pipelines, and cloud-based systems across the software development lifecycle.
I approach engineering beyond just making software functional. I care about the non-functional characteristics that determine whether a system can succeed in production — including scalability, reliability, performance, security, observability, and maintainability. I enjoy designing systems where these considerations are part of the architecture from the beginning, rather than problems addressed after the fact.
