About Me

I work across IT infrastructure, system administration, software testing and automation. My expertise is built on real-world administration and troubleshooting in both Windows and Linux environments.


From foundational desktop and laptop troubleshooting to deep OS installation and configuration, I ensure systems are stable and optimized. My core work involves server administration, networking, web hosting, and application deployment.


I actively manage and deploy database systems and containerized applications using Docker, secured and routed through Cloudflare. Furthermore, I implement robust QA testing workflows to ensure application reliability. I also leverage modern AI-assisted development tools (Copilot, Claude, ChatGPT, Lovable, Antigravity) to rapidly build, debug, and scale modern web applications.
