End to end, and out to the stores.
FIG. 00.6/HOW I WORK
Six rules I actually follow
-
Money is integer arithmetic
Currency does not survive floating point, and a shared bill is only trustworthy when every participant's device computes the same figure. Amounts are held and split as integer minor units under their ISO 4217 exponent, with the leftover cent distributed deterministically rather than rounded out of existence.
In practiceA cent-exact ISO 4217 multi-currency ledger, split by largest remainder — RM51.50 across four people resolves to RM12.875 before the remainder is assigned, not after.
-
Trust the server, not the client
Anything a client can compute, a client can also lie about. The writes that decide who owes whom run in Cloud Functions and are idempotent, so a retried request cannot double a debt, and everything else is bounded by Firestore Security Rules, which are what actually hold. App Check is integrated on the client, but enforcement across the callables is still switched off in source, so it is not yet a layer I claim.
In practiceIdempotent Cloud Functions behind Firestore Security Rules, with Remote Config. App Check integrated; enforcement pending.
-
Launch is the start of the work
A store listing is a commitment to keep shipping, not a finish line — the interesting version of a product is the one that survives its first month of real use.
In practiceFirst released 2 July 2026; version 1.2.5 reached the App Store on 27 July 2026.
-
Reliability claims need a test behind them
"It works" describes one run, not a system. Adelante's content pipeline — caching, deduplication, quality scoring, strict filtering — is covered by automated tests because a scheduled pipeline fails quietly, and the failure shows up on someone's Lock Screen rather than in a crash report.
In practice117 Dart unit tests over the client's content layer — library loading, deduplication, strict filtering, quality floor and refresh policy — with widget payload parity covered alongside.
-
Keep private data on the device
The safest place for a camera frame is the machine that captured it. Photoshoot runs its entire pipeline locally — Electron with context isolation, sandboxing and a strict CSP, WebGL2 for the effects, MediaPipe for face tracking — so nothing is uploaded in order to be processed.
In practiceLocal-first Electron/WebGL2 architecture; camera processing and captures stay on-device, with Firebase Hosting serving only the app itself.
-
Go native where the platform is the product
Cross-platform tooling is a default, not a rule. When the product surface is a widget rather than a screen, the framework has nothing to render into, so the widget gets written twice — properly — in the platform's own toolkit.
In practiceWidgetKit/SwiftUI on iOS and Android RemoteViews on Android, for Home Screen, Lock Screen and StandBy, over a shared Flutter app.

Quranic recitation platform · Frontend & UI/UX contribution
Redesigned the navigation, information architecture, and lesson flows inside another developer's Quranic recitation platform. A staged learning journey, a Qur’an reader that paints recitation rules into the script itself, self-testing, and an AI teacher — restructured so a learner always knows where they are and what comes next.

02/TOOLS IN MOTION
What I build with.
The lanes keep moving until you choose one. Hover to pause that lane, then browse it with its shaded edges. I learned most of this the long way, and the rest with the old cheat.The lanes keep moving. Tap a lane to pause it, then browse it with its arrows.
Before the tool list — the things I can take from an empty repository to a release.
-
Cross-platform mobile products
Take a Flutter application from an empty repository to a listing on both the App Store and Google Play, including the signing, the store paperwork, and the update cadence afterwards.
-
Native iOS and Android surfaces
Leave the framework where the framework cannot go — Home Screen, Lock Screen and StandBy widgets written natively on each platform and wired back into a shared app.
-
Backends, data and rules
Model the data, move the writes that decide anything into server-side functions, and constrain the rest with security rules instead of trusting the client.
-
Real-time graphics and desktop
Build interfaces that run on the GPU and ship as a desktop binary as readily as a web page, with the process boundaries locked down.
-
Applied AI in products
Put a model where it does a job a user can check — reading a receipt into structured line items, tracking a face on-device — rather than where it decides a number.
-
Release and product operations
Run the unglamorous half — versioning, subscriptions, remote flags, design handoff, and the release itself — so a build can be shipped on a schedule rather than when it happens to be ready.
The exact language set behind the shipped work.
Cross-platform products and the native surfaces around them.
Real-time state, exact data, secure rules, and APIs.
Vision, intelligence, subscriptions, and release infrastructure.
Versioned, designed, tested, packaged, and shipped.

LAST UPDATED 2026-07-29
Building
- Bupples
Maintaining the shipped product. It reached the App Store and Google Play on 2 July 2026 and was on version 1.2.5 by 27 July.
- CodeAtlas
Evidence for what a code change actually does — a change-intelligence system for TypeScript and JavaScript that maps a change through the codebase, picks the tests that can explain its impact, compares behaviour across base and head, and packages the result as a signed Change Passport. In design and documentation, not a service: there is no hosted app, no GitHub App, and the runner is local-only.
- Adelante
Widget-first motivation app for iOS and Android: native WidgetKit and RemoteViews surfaces over a scheduled Firebase content pipeline, with no accounts, analytics or ads.
- Photoshoot
Shipped in June 2026 and live in the browser: a local-first Electron and WebGL2 photobooth with 17 real-time GLSL effects and 8 on-device MediaPipe face effects. Not under active development.
Studying
- BSc Software Engineering (Hons) — Sunway University / Lancaster University
Software Architecture, Data Structures, Mobile Development, Databases, and UI/UX Design. Expected August 2027.
Looking for
- A full-time software engineering internship, January to April 2027
Subang Jaya or Kuala Lumpur, Malaysia. Mobile, full-stack, or anything that ships to a real store.
Exploring
- Inference that runs on the device
MediaPipe face effects executing locally in Photoshoot, so a camera frame never has to be uploaded to become useful.
- Model output as structured data, not prose
Gemini receipt extraction in Bupples: the model reads a photographed receipt into line items, and the ledger still does the money.
- Widgets as the product surface
Home Screen, Lock Screen and StandBy as places a product lives rather than shortcuts into it — which means two native implementations instead of one shared screen.
Let's build something memorable.
