Marvin Villamar

I build production web, mobile, and reactive backend systems — and use generative AI and AI-assisted development to design, build, and ship them faster.

Right now I'm building SmartFleet for Royal Caribbean Group.

SmartFleet

Royal Caribbean Group · Sep 2025 — Present

A crew-facing guest experience platform used daily on every ship in a 71-vessel fleet. I build and maintain both tiers: the Next.js web app and the reactive Spring API that aggregates 10+ enterprise systems.

TrackJob
Your whole job search in one dashboard. TrackJob finds open roles that match your résumé, then tracks every application for you: it reads your Gmail and moves each one from applied to interview to offer on its own. Interview prep and your progress live in the same place, so you never juggle job boards, spreadsheets and inboxes again. Try it as a guest, no sign-up needed.
