I’m a systems integrator who learned the hard way: in the field, under load, and with users who can’t wait. I’ve built and repaired everything from satellite links and voice‑alarm systems to Windows/Linux fleets and privacy‑first learning platforms.
Today I combine hands‑on infrastructure with auditing and training so teams don’t just pass an audit — they stay resilient when real life happens. I work with persistence, precision, and a bit of humor — and I document the path so others can repeat it.

I’m a systems integrator who learned in the field: rooftop satellite fixes, hospital zero‑trust rollouts, and clusters built on second‑hand laptops. I combine hands‑on infrastructure with audits and training, so teams don’t only pass audits — they stay resilient when real life happens.
