What I'm looking for

I’m looking for a role where I can combine secure, high-accuracy end-user support with practical performance improvements—owning troubleshooting, ticket resolution, and automation while continuously learning and strengthening resilient systems.

I’m a Dedicated and proactive Mid-Level Technical Specialist with over 4 years of experience spanning Systems Administration and Full-Stack Development. I specialize in building and maintaining resilient technical ecosystems, from high-traffic web architectures (React/Laravel) to end-user support that improves reliability and operational efficiency.

In end-user support roles, I’ve provided comprehensive on-site and remote IT support for 3,000+ users, resolving 10–30 tickets daily with a 100% resolution rate. I enforce security-first practices using ESET and handle advanced diagnostics across Windows, macOS, and LAN/WLAN issues.

On the development side, I modernized platform architecture by managing Front-end (React) and Back-end (Laravel/Voyager) work, re-engineering APIs for smoother integration and eliminating legacy lag through performance tuning. I’m passionate about automation, self-learning environments, and keeping systems stable—even during high-traffic surges.
