2210 IT Jobs

Most people on USAJOBS.gov only need jobs in their own profession, and the main site can be cumbersome for that. I built a static site generator, inspired by Hugo (which I used years ago), that publishes every open federal IT Specialist (2210) job as one fast table with keyword and vector similarity search.

A separate data pipeline cleans, formats and embeds the postings on a slow refresh, since federal jobs don’t need second-by-second updates. The generator pulls that data at build time and ships a plain static page: no server, no database, no AI model in the browser.

Overview

CISSP (ISC²), 2025

I work on cyber stuff.

I enjoy working on zero trust stuff.

I’m also developing a Retrieval-Augmented Generation (RAG) project aimed at AI-driven security analysis and evidence generation. Details and a live demo will be added once the project is ready for public release.

Focus Areas

Designing and hardening Zero-Trust and Privileged Access Management architectures across hybrid-cloud and on-prem CIS environments.
Producing accreditation evidence for FISMA Moderate/High and DoD DISA SRG IL4/IL5 systems.
Leading enterprise vulnerability management and developing custom remediation strategies for complex findings.
Using Infrastructure-as-Code (Terraform, Ansible, GitHub Actions) to make security controls repeatable and auditable.
