I build fast, thoughtful ops dashboards and the security products built around them.

01About

A little about me.

I build complex operational interfaces for infrastructure security — designed to stay clear, fast, and dependable when operators need them most.

With nearly six years in production — including over three at a server security company — I've spent most of that time on the dashboard that communicates with security agents running on Linux VPS servers: configuration, IP reputation, domain patterns, and the control surfaces operators rely on daily. I've also worked heavily on a WordPress security plugin that routes through the same agent infrastructure.

Outside of work, I like to travel and explore new places.

Data Rich UI & Platform Integration

Complex, data heavy interfaces: dynamic tables, configuration panels, charts, and widgets, integrated with a large ecosystem of agents, backend services, and internal platforms such as Rancher, Jenkins, and Kibana.

  • ag Grid & data dense tables
  • Forms & configuration panels
  • Rancher / Jenkins / Kibana tooling
  • PR reviews & frontend mentorship
  • ag Grid

WordPress Security Product

Contributed to a WordPress security plugin, delivering the admin interface and backend logic that brings agent integration and website security features directly into WordPress.

  • Plugin admin interface
  • Agent integration layer
  • Security feature workflows
  • REST API & PHP backend
  • React
  • PHP
  • WordPress
  • REST
03Pet projects

Built outside the day job.

Augmented by AI workflows to bridge the gap between solo execution and complex browser graphics, accelerating these experiments to a scale that used to be out of reach for a single developer.
