SSH Client & Terminal - Cura
iOS · Android
A real SSH terminal plus a live server dashboard on your phone. Cura reads CPU, RAM, disk, Docker and logs over plain SSH — nothing to install on the server — and pages you when a threshold breaks.
Saltserv · Amsterdam
I build native apps.
12 of them are on the stores.
Swift on iOS, Kotlin on Android, Compose Multiplatform where sharing code makes sense. An SSH client, a voice recorder that never touches the cloud, a package tracker that doesn't read your email, a fiqh reader, a baby-names app with cited sources. No accounts, no telemetry, no rented SaaS. For clients, the same care goes into backends and internal tools.

Islamic Baby Names Generator - Ismi
iOS · Android
Swipe through 1,826 Islamic and Arabic baby names — Arabic script, pronunciation, and a meaning traced to a real source. 565 carry a verified Quran citation. Match with your partner. No ads, fully offline.
Mantra: Affirmation Wallpaper
Android
Write one line you want to live by; it's on your lock screen in under a minute and arrives on a new illustrated background every morning. Your words, your photos if you like, nothing uploaded.
QuestLog: Game Backlog Tracker
Android
Save any game in two taps, sort your backlog, and when you can't decide, spin the roulette. Time-to-beat on every title, a 'pile of shame' counted in hours, and share cards when you finally beat one.
One calm list of everything you're waiting on, across 900+ carriers. Paste a number or scan a barcode, get a Live Activity on delivery day — and never hand an app your inbox.
Paraphrase and translate in 30+ languages, summarise, fix grammar and tone, and pull text out of photos and PDFs — with an AI that runs on your iPhone instead of a server.
Reading Journal - Booksum
iOS · Android
Photograph a page, keep the passage with the book it came from, and get a private on-device summary. A bookshelf, a quote collection and a reading journal in one — nothing leaves the phone.
Shia Islamic Laws & Fatwas - مرجعي
iOS · Android
The complete book of Sayyid Sistani's rulings — every masʾala, letter for letter from the official source — with chapter browsing, diacritic-tolerant Arabic search and bookmarks. Offline, free, no ads.
Ward: Porn & Website Blocker
Android
Pick what to block, turn on the filter, done. The lock is what makes it stick: switching anything off takes a waiting time from one hour to a week, and a friend can hold the unlock code. Nothing leaves your phone.
ADB Remote
macOS
A native macOS window for the ADB and Gradle commands you run fifty times a day — logcat filtering, installDebug, file pulls, screenshot diffs — without launching Android Studio.
Tap, talk, and Murmur writes the note — transcribed and tidied entirely on your iPhone. Ask it questions about what you said, set reminders by voice, export Markdown. Nothing ever leaves the phone.
Type a message, print it one big letter per page, cut and glue it onto a fan. Then save up for the show, keep every photocard, and never miss a ticket deadline. No ads, no account, nothing leaves your iPhone.
Client work
All case studiesThe other half of the job: Android apps for other companies' products — a guitar-tuner maker, a car marketplace, an EV-charging rewards programme, an AI parenting startup — and a backend-plus-web planning system for a fibre contractor.
Dynet
Fibre rollout · Web · API
Districts arrive as the network operator's Excel sheet; Dynet turns them into buildings, flats and a work queue for six specialist roles — surveyors, planners, installers — with calendars, floor plans down to the cable, and live progress per district. API, web app and import pipeline, built by me.
Case study
Fibre rollout · October 2023 – present
A planning and tracking system for fibre-to-the-home installations in Dutch housing districts
- REST API with JWT auth in httpOnly cookies, role-based access, rate limiting, OpenAPI docs
- Excel import pipeline: header matching, validation, preview, conflict check, transactional import with live progress
- Role-specific web app: dashboards, calendars, apartment workflows, drag-to-prioritise districts
- Building layout editor with twelve floor-plan schemas and floor-to-cable mapping
- Seeders, tests, structured logging and health probes for day-two operations

Android apps built for clients
Roadie Tuner
Music hardware · Android
A free chromatic tuner for twelve instruments and the control centre for Band Industries' Roadie devices: connect over Bluetooth, push firmware, manage instrument profiles and 150+ alternate tunings. I built the Android app; 100K+ installs, rated 4.6 on Google Play.
Case study
Seez
Automotive marketplace · Android
Seez aggregated used and new car listings across the UAE, Saudi Arabia and Kuwait into one search, priced them with market data, and could identify a car from a photo. I built the Android app — 500K+ downloads — for a company that grew to a million users and was acquired by Pinewood Technologies in 2025.
Case study
PowerGoodies EV Rewards
EV charging · Android
Public chargers are blocked by cars that finished hours ago. PowerGoodies rewards EV drivers with points for charging at partner operators in the Netherlands, Belgium and the UK and for unplugging right after the car is full — points they spend on gift vouchers. I built the Android app end to end: charge map, session tracking, timers, notifications and the rewards shop.
Case study
Bubu AI
Parenting · early childhood · Android
Bubu is an AI parenting companion: an assistant that answers from your child's own profile, sleep predictions, personalised stories and lullabies, and a nursery hub that connects parents with their daycare. I built the Android app — Kotlin, Jetpack Compose, 20+ Gradle modules — to parity with the iOS app, plus the Android teacher app for nurseries.

Why these exist
Every origin storyEach app started as something that annoyed me. These posts are the engineering notes: what the problem was, what I tried, what shipped, and what I'd do differently.
Cura
Why I built Cura: an SSH client that shows you the problem before you open a shell
The 2 AM pager problem, why Cura reads /proc over plain SSH instead of installing an agent, how the health score is weighted, the BouncyCastle bug that silently broke TLS for every SDK in the app, and why Pro is a one-time purchase.
Ismi
Why I built Ismi: a baby-names app where every meaning has a source
Most Islamic baby-name apps ship meanings copied from each other, some of them wrong. How Ismi's names pipeline works — Wikidata harvest, Quran citation verification against the Quranic Arabic Corpus, an LLM judge that rejects homographs like 'Matt → he died' — why the app is sect-neutral, and why it ships two native apps from one dataset.
Mantra
Why I built Mantra: your own words on the lock screen, and the Android bug where setting a wallpaper kills your Activity
Affirmation apps push other people's quotes; wallpaper changers have no words. Mantra is the gap between them. The Play Store keyword that decided the name, the Material You re-theme that recreates your Activity a second after you set a wallpaper, WorkManager's first-run surprise, adaptive scrims from luminance stats, and why user photos are never paywalled.
QuestLog
Why I built QuestLog: a game backlog tracker with a roulette wheel, and the API that died halfway through
The Friday-night problem: more games saved than played, and an hour spent choosing. QuestLog's roulette wheel, why time-to-beat is the most important field in the app, what happened when RAWG shut down mid-build and IGDB replaced it, shipping a Kotlin Multiplatform codebase to Google Play, and two Compose bugs that cost real days.
Guides and notes
All postsDesign notes from Dynet: Excel as the integration contract, transactional imports, and six roles on one API
Engineering notes from building a fibre-installation planning system on Node.js, MongoDB and React: matching hostile Excel headers, importing inside a transaction with live progress over SSE, and running six roles through one JWT-guarded API.
QuillBot and Grammarly alternatives on iPhone — including the one already built into iOS
A fair comparison of paraphrasing and grammar tools on iPhone — QuillBot, Grammarly's keyboard, Apple's Writing Tools, and Textrix — on languages, rewrite styles, OCR and PDF support, pricing, and whether your text leaves the phone. Written by the developer of one of them.
Otter alternatives that work offline: on-device voice transcription and notes on iPhone
A fair comparison of voice-to-text and AI note apps on iPhone — Otter, Apple's Voice Memos and dictation, Aiko, and Murmur — on where the audio goes, what happens to the transcript afterwards, pricing model, and what actually works in airplane mode. By the developer of one of them.
Parcel, AfterShip, Shop or Underway? Choosing an iPhone package tracker by what it asks for
A fair comparison of the package-tracking apps people actually install on iPhone — Parcel, AfterShip, Shop, the carriers' own apps, Apple's built-in tracking — judged on carriers covered, delivery-day features, price model, and whether the app wants your inbox. By the developer of one of them.
