We Build Custom Mobile Apps That Help Startups Launch Fast

From idea to app store, we help founders, creators, and small businesses build cross-platform mobile applications using React Native — fast, affordable, and scalable.

Tech Expertise + Startup Mindset

JBS Site Services isn’t just another agency — we’re problem solvers. Our founder studied Computer Science at Pitt and has spent years building software using React Native. Now, we help others launch mobile apps that are fast, functional, and user-friendly — without the bloated price tags.

​

We specialize in early-stage MVPs, side hustle ideas, and custom tools for small teams.

​React Native Apps Built for Speed & Scale

  • 📱 Cross-Platform Mobile Apps — Android + iOS from one codebase

  • 🚀 MVP Prototypes — Launch fast, test your idea, iterate with confidence

  • 🔐 User Auth & Database Integration — Firebase, Supabase, custom backends

  • 🛠️ Business Tools — Booking systems, dashboards, customer portals

  • 💼 App Design & UX Collaboration — Beautiful and intuitive interfaces

This Might Be Our First App With You — But Not Our First Build

We’ve worked with React Native on countless internal projects and web applications — we know how to take an idea and make it work. While this is a new service for JBS Site Services, our experience in building responsive, functional, and scalable software speaks for itself.
