Prototypes you can tap
Every screen designed and linked into a clickable prototype before any code, so you can test the idea with real people and change it cheaply.
A studio that puts mobile first: tappable prototypes, Android and iOS apps, web apps and the backends behind them, all the way to release.
Services
What HEXHAD can build for you.
From the first prototype to the server and the store listing, one engineer does every part, so nothing gets lost between design, app and API.
Android and iOS apps
Native Kotlin and Swift, or one React Native codebase for both phones. Fast, usable offline and ready for the stores.
APIs and backends
The server side your app needs: Spring Boot or TypeScript services, databases, user accounts and push notifications, shaped around how the app uses them.
Web apps
Dashboards, admin panels and tools that run in the browser on any device, sharing one backend with your mobile app. Wasthu dimensions is one of them.
Mac and Windows tools
Desktop apps that sit inside your workflow, like NotchPal, Droid Transfer, DiskKeeper, Hive and Latch.
Native modules
When React Native has no library for what you need, HEXHAD writes one in Kotlin or Swift, the same way its open source packages are built.
Launch, then keep it running
Release builds, store listings and the updates that follow once real people use it.
Work
Apps of its own. Each one does one job well.
The best way to judge a studio is by what it has shipped. Most are live on Google Play, the Mac and the web, and a few are still in the works.
Android
Everyday tools for your phone, from QR codes to audio editing. Most are on Google Play.
Mac
Small utilities that live in the notch and the menu bar, and move files to and from Android.
Web
Games and tools that run in any browser, with nothing to install.
For developers
Tools for people who build apps: simulator cameras, performance checks and Claude Code.
Proven in public, on npm.
Packages pulled out of real app work and released under an open licence, free for any team to use.
@hexhad/react-native-global-modal
Global alerts for React Native with priority queues, custom styles, and both declarative and imperative APIs.
react-native-nitro-otp-verify
Automatic OTP reading from SMS on Android, built on Nitro Modules for the New Architecture.
react-native-nitro-sms-user-consent
SMS OTP reading in a single tap on Android with Google's SMS User Consent API, built on Nitro Modules. No app hash needed, with a useOtpVerify hook.
How HEXHAD works.
The rules behind every app, including the one you bring.
One clear job.
An app should solve one problem well and then get out of the way. Scope stays small and sharp.
Your users' data stays theirs.
Where an app can work on the device and without an account, it does. Less to secure, less to break.
Built to last past launch.
Clean, documented code you own, with reusable parts tested in real apps before they reach yours.
Studio
You work directly with Hashan.
HEXHAD is the studio of Hashan Dharmapriya, a senior software engineer in Colombo, Sri Lanka, who leads mobile products at Mainframe. Every HEXHAD project is designed, built and shipped by him, so you always talk to the person writing the code.
