Systems Administrator · MrBeast

Infrastructure that isn't allowed to fail.

Nine years keeping high-stakes production alive — Facebook, then seven years at Apple, now MrBeast. I also build the software.

Selected work

Real-time systems for productions that only happen once.

Two tracking platforms I designed, built and operated live. No second take, no rehearsal, no rollback.

I Survived The Most Extreme Places On Earth

Expedition race · Peru, Ecuador & Argentina

Satellite GPS from Garmin inReach devices over the Iridium network, through a webhook pipeline into a Next.js/Redis app on Vercel — roughly 25 seconds end to end. Powered a live leaderboard scoring each team against its own scouted route, with snap-to-route positioning, off-course detection and producer-controlled scoring.

Escape 100 Cops, Win $500,000

Pursuit format · 115+ GPS units, one map

A mixed hardware fleet — 4G cellular trackers plus GPS ankle monitors — on contestants, pursuit teams and camera operators, reporting through a telematics pipeline into a Next.js/TypeScript app. Layered with geofence zones, stillness detection, and a one-second alarm path that turns a contestant's own phone into their siren.

Companies

Two businesses I own and run.

Alpha Professional Painting Corp

CEO · CSLB #1126241 · Bay Area & Central Valley

A California-licensed painting corporation serving residential and commercial clients across 21 cities. I run the company and built its site — regional SEO pages, a lead funnel, and license verification surfaced on every page.

Black Rose Athletics

Founder · 2023 — present

A bootstrapped plush toys and collectibles brand with no outside funding, run solo — product design, manufacturer sourcing, inventory forecasting, fulfillment, and marketing across Instagram, TikTok and paid social.

Client sites

Shipped end to end, down to the DNS.

After the third build I stopped rewriting the same funnel and factored it apart — one shared base, each look reduced to a file of custom properties.

Experience

Nine years, three of the hardest rooms in tech.
