About Sean

IT Director and technologist with nearly two decades of experience leading enterprise IT at Tribalco, a defense contractor with 10 global offices. I hold an active Top Secret DoD clearance.

My most significant recent work spans two fronts: guiding Tribalco through CMMC Level 2 C3PAO certification — one of the most rigorous cybersecurity compliance frameworks in the defense industrial base — and designing and deploying a secure, private AI platform for company-wide use. That AI implementation was architected from the ground up to meet the security and privacy demands of a cleared defense contractor environment.

Beyond my role at Tribalco, I build applications, scripts, and automation tools using Claude Code, OpenAI Codex, and GitHub Copilot, and I'm passionate about helping organizations adopt AI practically and securely — not as a buzzword, but as genuine operational leverage.

At Tribalco, I oversee all IT systems and staff for a 170-person organization with offices across the US and internationally, managing vendor relationships, departmental budgets, and a technology portfolio spanning infrastructure, security, and software development.
