Mobile App Development

Apps that live on your customers' phones — bukan shortcut to a website.

Flutter: one codebase for Android and iOS. From design, API and notifications through to live di Google Play — and updates that do not break your existing users.

What I built

From the customer app to the company's internal tools.

A successful app is not just pretty screens. It is about correct data, notifications that arrive, and updates that break nothing.

Customer app

Catalogue, bookings, payments, membership, chat and profile — the full flow from sign-up to transaction.

App dalaman

Field staff: job records, photo uploads, signatures and reports that reach the office immediately.

Auth & keselamatan

Biometric sign-in, secure tokens, sessions that expire on their own, and no sensitive data stored on the phone.

Notifikasi & push

Push, in-app and WhatsApp — scheduled, targeted by segment, and never sent at the wrong hour.

API & backend

One API for the app, the website and the admin dashboard — so the numbers on the phone match the numbers in the office.

Offline & prestasi

Local cache, resync, and screens that stay responsive even on a slow connection.

Penerbitan Play Store

Store listing, icon, screenshots, privacy policy and Google review approval — not just an APK file.

Integrasi pihak ketiga

Maps, camera, payments, WhatsApp, e-invoicing and existing systems — connected properly, never faked.

Maintenance after launch

OS updates, crash fixes and new versions without forcing existing users to lose their data.

Why Flutter

Satu kod. Dua platform. Kos selenggara separuh.

Building two separate apps means two codebases, two sets of bugs, and twice the work for every new feature. Flutter solves that without giving up the native feel on either platform.

Proses

From idea to the Play Store, with no surprises.

1

Skop & aliran

Who the users are, what they do every day, and what the one core action of this app is.

2

Reka bentuk

A real, touchable screen prototype — before a single line of code is written.

3

Bina & API

The app and the backend are built together, so the data, the roles and the payments stay consistent.

4

Ujian peranti

Testing on real devices, not just emulators: screen sizes, Android versions, slow connections.

5

Play Store

Listing, privacy policy, Google review and launch — with an update plan.

The questions we get asked most.

How long does it take?

An app MVP is usually 6–10 weeks, including design and the Play Store release. Apps with a complex backend, payments and multiple roles are split into phases. The real dates are set once the scope is locked.

Can it also ship on iOS?

Yes. Flutter supports both, and the same code can be built for the App Store. Take into account: an Apple Developer account, a stricter App Store review, and extra time for the certification setup.

Do I need my own Google Play account?

Recommended, yes — the account stays yours even if we stop working together. I help set up the account, the listing, the privacy policy and the review process. A Google Play developer account carries a one-off fee.

Do I own the code and the data?

Yes. The source code, the design assets and the database are handed to you. No vendor lock-in: another developer can take the app on at any time.

Is there support after the app goes live?

There is a support window for bug fixes and Android-update compatibility. After that a monthly maintenance package is available — or you can run it yourself with the documented code.

Got an app idea stuck because nobody can build it?

Tell me one problem this app solves, and who will use it every day. I will answer with an honest opinion — including whether it should be an app at all or a website is enough.

We usually reply within one business day.
