> systems, secured, sustained.
Developer, sysadmin, and security hardening specialist — building the portals institutions depend on, and locking down the servers they run on.
I build the web systems that institutions run their daily operations on, keep the servers those systems live on stable, and harden the perimeter around both. Most people specialize in one of these — doing all three means nothing gets lost in translation between the person who writes the code, deploys it, and defends it.
My work sits mostly in education-sector and public institution systems — registration platforms, staff directories, feedback pipelines — plus the Linux infrastructure and network hardening that keeps them online and safe.
PHP platforms for registration, staff records, and feedback — built for the way institutions actually work.
Linux server administration — deployment, service reliability, and the quiet maintenance that keeps uptime boring.
Firewall rules, access control, and shutting the doors that were never meant to be open in the first place.
End-to-end application review, status tracking, and document workflow for a state-level education authority.
Searchable staff records with on-demand ID card generation for a government department.
Structured feedback intake with automated routing straight to the team that owns the issue.
Full access-control audit and firewall rebuild across production infrastructure — closing legacy remote-access tools and enforcing key-only authentication.
