Mobile products live and die on their backend. The app is the part users see, but the API, the authentication, the notifications and the sync are what actually work or fail, often over a train-tunnel connection on a phone that has not been updated in six months. I build backends designed for that reality.
One backend, every platform
I build a single, well-designed API that serves your iOS app, your Android app and your website, with token-based authentication and careful versioning. The alternative, logic duplicated per platform, is how products drift into inconsistency and triple their maintenance. One source of truth keeps every client in step.
Built for mobile conditions
Mobile backends face problems web backends do not: flaky networks, aggressive caching, offline periods and users who upgrade the app whenever they feel like it. I design for all of it, with API versioning so old app versions keep working, sensible retry and sync behavior, and endpoints shaped around how the app actually uses them rather than generic CRUD.
Notifications, uploads and the rest
Push notifications through Apple and Google's services, coordinated by your backend with device token management and user preferences. File and image uploads that go straight to object storage via signed URLs, so uploads scale independently of your servers. Background jobs for anything slow. The pieces a real mobile product needs, built properly.
Progressive web apps
Not every product needs a native app or the app store tax. A progressive web app installs to the home screen, sends push notifications and works offline, at a fraction of native cost and with no review cycles. When that fits your product better, I build it, and you ship native later only when users prove they want you in their pocket.
Who this is for
Teams building a mobile app who need the backend done right, and businesses who want an installable, app-like experience without committing to native development. If mobile is your channel, the infrastructure behind it is what I build.
