Drum Bun, by Romanian InsurTech startup Explorom, is the single mobile app Romanian drivers use to keep their car compliant: verifying RCA insurance, ITP technical inspection, and road vignette by license-plate number, then purchasing or renewing them in-app. 7Code built the React Native iOS + Android client and the Node.js backend on Heroku, plus the OCR document pipeline that lifts car details from a photo so drivers stop typing license plates and policy numbers by hand.
Take three fragmented Romanian car-service flows and hide the bureaucracy behind one tap.
Romanian drivers juggle three separate compliance services, RCA insurance, ITP inspection, and the road vignette, each with its own provider, expiry date, and renewal flow. Drum Bun's pitch is one app for all of it: instant verification on a plate, alerts before anything expires, OCR-assisted onboarding, and in-app purchase. Building it meant pulling together a robust foundation, an OCR pipeline, and a payment layer that drivers actually trust.
- Three independent compliance services unified behind a single product surface
- OCR pipeline robust enough to read messy real-world car documents
- Auto-complete and pre-fill so drivers don't manually type plates and details
- Custom expiry-alert engine for RCA, ITP, and vignette per car
React Native + Node.js, walkthrough-first onboarding, OCR-driven document capture.
We built Drum Bun on React Native with a Node.js backend on Heroku. The app opens with verification (RCA, ITP, vignette by plate, no signup required), funnels users into a Sign Up only when they need to do more, and leans on OCR to lift documents from photos, so adding a car takes seconds, not minutes. Modules cover walkthrough, car management, alerts, OCR, profile, services, and payment methods, with purchase history stored alongside each car.
