hi, I'm,
Douglas Maringa.
Developer, app rescuer, & a serial shipper.
Ten-plus years building apps in React and React Native, with 60+ MVPs shipped across SaaS, marketplaces, AI tools and mobile, and still more curious than when I started. JetBuild Studio is US-registered and works with founders everywhere.
p.s., yes, I answer my own email.
that's me,
I · who I am
One senior developer, not an agency relay.
When you work with JetBuild, you talk to the person writing the code. No account managers, no handoffs, no telephone game between you and the build. That's why fixed prices are possible, and why 90% of clients come back.
II · what I do
Build, rescue, migrate, audit.
New MVPs on Bubble or custom code. Rescues when a build has stalled or a developer disappeared. Migrations off platforms that don't want to let you go. Security audits before real users arrive. And $1,200 websites for local businesses that just need to win jobs.
III · what I've made
60+ shipped products.
Funded marketplaces, hiring platforms, AI tools, fitness apps, and one migration a platform said was impossible. See the work.
IV · watch me work
I teach this stuff on camera.
Draftbit had me record their official mobile app build series, and my own channel has full multi-hour builds with Next.js, Stripe and Supabase. If you want to know how I work before we ever talk, press play.
Got something stuck, or something to build?
Twenty minutes, straight answers, and a fixed price if it's a fit.
