Apps that extend the systems you already run
Most business apps are not standalone products. They are a phone-shaped window into something that already exists: an order book, a customer list, a stock register, a job schedule. The app is only useful if it shares data with that system in real time.
I build the app and the API together, so the phone, the browser dashboard and the database stay in agreement. A delivery marked complete on a rider phone updates the office screen immediately, and works offline until signal returns.
What I build
Customer-facing apps for ordering, booking, tracking and loyalty. Field-staff apps for delivery, service visits, site inspections and attendance with GPS and photo capture. Owner and manager apps that surface sales, stock and collection figures without opening a laptop.
Companion apps that sit on top of an existing ERP or CRM are the most common request: approvals, alerts, quick lookups and data entry from wherever the work actually happens.
Platform and technology choices
React Native with TypeScript covers Android and iOS from one codebase, which keeps build cost and ongoing maintenance close to half that of two native apps. Where a feature genuinely needs native code, that module is written natively and bridged.
The backend is the same Python or Node.js and Postgres stack behind the web applications I build, so there is one source of truth rather than a second database that drifts.
Offline, notifications and the practical details
Indian field conditions mean patchy connectivity is the norm, so writes are queued locally and synced when the connection returns, with conflict rules agreed up front rather than guessed at.
Push notifications, WhatsApp fallbacks, biometric login, in-app updates and Play Store and App Store submission are all part of delivery, not an afterthought.
Frequently asked questions
Do I need separate Android and iOS apps?
Usually no. A React Native codebase produces both, which keeps cost and maintenance down. Separate native apps only make sense for heavy graphics or deep platform integration.
Can the app work without internet?
Yes. Data needed in the field is cached on the device and changes are queued, then synced automatically when connectivity returns.
Can the app connect to our existing ERP or CRM?
Yes, if it exposes an API or a database we can read. Where none exists, I build the API layer as part of the project.
Do you handle Play Store and App Store submission?
Yes, including developer account setup, store listings, screenshots, privacy declarations and review responses.
How long does a mobile app take?
A focused single-purpose app typically ships in four to eight weeks. Apps with payments, multiple roles and offline sync take longer and are quoted after a scoping call.
