I build for the browser and the pocket.
AWeb
React, Next.js and TypeScript. At Truedune Beauty I reworked checkout with Magic Checkout and single-click buy, and ran six A/B tests across the storefront.
BBrowser
Chrome extensions on Manifest V3: ShopGrade, TubeFocus, Keeptake, TabCluster and CSS Class Highlighter.
CAndroid
Native apps in Kotlin and Jetpack Compose: SecureVault, Companion AI, Speaker Cleaner, Nicked and Compass.
Nineteen projects: eleven products of my own under CodeHorizon, six for Chrome (two no longer live) and five for Android (one still in testing), websites for a client and my studio, an Android ROM, and earlier work from 2021 to 2023. Four of them, up close.
01
An audit for any Shopify storefront. It turns what it finds on a public store into a prioritized list of fixes, with no admin access needed.
Hard partKeeping what the page shows separate from measurements and AI-written suggestions, so merchants know what is fact.
02
An encrypted vault behind a calculator that really works. Type your code and press equals, and a separate vault password or your fingerprint opens it.
Hard partMaking the disguise feel exactly like a calculator, and keeping Keystore keys intact across app updates.
03
YouTube on your terms. Choose Learn, Watch or Explore, it hides the rest, and a 60-second Peek brings it back for a moment.
Hard partA focus timer and a 60-second Peek that keep running after the popup closes and Chrome puts the extension to sleep, without touching your saved switches.
04
One mystery cricketer a day, revealed one clue at a time. Name them on an early clue for more runs, and even a wrong guess shows what it shares with the answer.
Hard partGetting 403 international cricketers right, from legends to today’s players, each checked against a published source, so no clue is ever wrong.
Everything else I’ve made
Point at one for a look. Each has a case study.

Six Chrome extensions and five Android apps, each from the first sketch to the store listing. Eight are live, Compass is in testing, and Notilo and TabCluster are no longer live.

Nine launches and seventeen updates so far, from SecureVault 7’s decoy vault to TubeFocus 7’s 60-second Peek and Nicked’s public launch on Google Play.

SecureVault, TubeFocus, TabCluster, Keeptake, Companion AI, Nicked, Speaker Cleaner and Compass never ask you to sign up, and keep what’s yours on your device.
Private by design
Along the way came a chat room on Flask and Socket.IO, a filter that turns photos into pencil sketches, two internships, a client’s website and a frontend role on a Shopify storefront.
Four habits, and the code that shows each
In ShopGrade the extension only asks. A server function checks the plan, credits, verified email and trial before any report, and spends a credit in one transaction, so a crash can’t take a credit without giving what it paid for.
const spend = await runTx(async (txId) => {
await db.decrementDocumentAttribute({
databaseId: DB, collectionId: PROFILES, documentId: meterId,
attribute: 'creditsBalance', value: 1, min: 0, transactionId: txId,
});
await db.incrementDocumentAttribute({
databaseId: DB, collectionId: PROFILES, documentId: meterId,
attribute: 'creditAiBalance', value: 1, transactionId: txId,
});
await db.incrementDocumentAttribute({
databaseId: DB, collectionId: PROFILES, documentId: meterId,
attribute: 'creditCroBalance', value: 1, transactionId: txId,
});

SecureVault has no account and no upload. Its master key is made in the Android Keystore and never leaves it, and every file is streamed through AES-256-GCM, its name included.

MasterKey.Builder(context)
.setKeyScheme(MasterKey.KeyScheme.AES256_GCM)

In TubeFocus the popup and the settings page only send requests. The service worker applies them one at a time, so two open pages can’t overwrite each other’s changes.
// One writer keeps edits from separate popup/options pages from overwriting one another.
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
// …
pendingWrites++;
const operation = writeQueue.then(async () => {
const current = await readSettings();
// … the command, applied to the settings it just read …
await chrome.storage.sync.set({ [STORAGE_KEY]: exportSettings(next) });
// A sync quota failure must not cancel an otherwise valid local peek.
if (command.action === 'reset') await chrome.storage.local.set({ [REVEAL_KEY]: next.reveal });
return next;

Nicked’s daily schedule is shuffled in Kotlin on the phone and in Python in the data scripts. Both use the same SplitMix64, and a golden test catches any drift between them.
/** Fisher-Yates with SplitMix64. Our own PRNG so the order never changes across Kotlin versions. */
fun seededShuffle(items: List<String>, seed: Long): List<String> {
val out = items.toMutableList()
val rng = SplitMix64(seed)
for (i in out.lastIndex downTo 1) {
val j = rng.nextInt(i + 1)
val tmp = out[i]; out[i] = out[j]; out[j] = tmp
}

The Android app people use to upload photos to Wikimedia Commons, the free media library Wikipedia uses. 100K+ downloads on Google Play.

If the upload screen was recreated while the photo editor was open, as on a switch to dark mode, the edit was lost and the original uploaded, and the location picker crashed. The screen now looks its upload up by position each time.
A bug first reported in 2019: the app made a sound for every file while uploading. Progress now has its own silent channel, and only the result alerts you.
One class with 27 functions, over the project’s limit, is now the screen and two tested helpers, and it works as it did.
Share a RAW file next to its JPEG and the RAW was copied, then thrown away: 12.6 MB per photo in my test. Unsupported files are now skipped before copying, and the warning still shows.
