Summary
Professional summary
My journey in technology started with web development and computer networking before expanding into computer repair, ISP networking, VPN infrastructure, and Network Operations Center environments. Over time I moved deeper into Linux systems, virtualization, servers, cloud platforms, automation, and backend engineering. Working across both software and infrastructure taught me that production systems cannot be understood from only one layer — applications depend on operating systems, storage, networking, virtualization, and physical infrastructure, while infrastructure increasingly depends on reliable software and APIs. That perspective led me toward platform engineering and founding Kilat Cloud.
Career objective: Developing a career as Network Engineer, Cloud Engineer, Platform Engineer, DevOps / Infrastructure Engineer, SRE, Backend Engineer for infrastructure platforms, and Cloud Platform Developer — with focus on cloud infrastructure, Linux, networking, BGP, virtualization, distributed storage, automation, observability, and disaster recovery.
