Cover image for ONEai Health — a clinical
ONEai Health — a clinical monitoring app, from ring basics to seventeen vitals Patients enrol through their healthcare provider and wear an FDA-cleared smart ring. The app had been live about a year when I joined, and its public reviews weren’t about polish — they were about readings that didn’t arrive and a ring that wouldn’t stay connected. I came in as primary Android engineer and built most of what the product does today. The core problem was that health data arrived three different ways — the ring over Bluetooth, Android Health Connect, and the patient typing it in — and each path had grown its own handling. I converged all three onto one per-vital model, so every one of the seventeen vitals renders, charts and uploads identically no matter where its numbers came from. From there: seventeen health-vital surfaces, Health Connect sync, a structured daily diary and an AI chatbot, across roughly seventy-five screens. Then the client brought a new design, and I reimplemented the entire interface against it without touching the business logic underneath — which is the whole argument for keeping the two apart. Live on the App Store and Play Store, now maintained by an internal team

Cover image for Sales-Edge-AI — an AI sales
Sales-Edge-AI — an AI sales coach for Android and iOS, from one Kotlin codebase A sales rep records a client meeting on their phone. The app transcribes it, scores the conversation, and files it against the right opportunity in the pipeline. Twenty-five screens, fourteen features, Android and iOS — built by one person. The whole product runs on a single Kotlin Multiplatform codebase with Compose Multiplatform for the UI, which means both apps share their screens, not just their networking layer. That works right up until it doesn’t, and the place it doesn’t is recording — the one thing the product lives or dies on. Android and iOS have different audio APIs, different rules about what a backgrounded app may do, and different ways of taking the microphone away mid-session. So the recording session sits behind one interface in shared code and is implemented twice underneath: MediaRecorder with a foreground service on Android, AVAudioRecorder reached through a C-interop bridge with a background audio session on iOS. Fourteen platform boundaries like it across the app. Everything above them is shared.

Cover image for Baritastic — two codebases became
Baritastic — two codebases became one, with nothing patients relied on changed A bariatric-care app used daily by people managing a medical recovery. A million downloads, half a million users, running since 2018 on two separate codebases — Android in Java, iOS in Objective-C — with crash-free sessions down to 98%. I led the consolidation onto Flutter as mobile lead, with four to five engineers. The rule we worked to was that no feature could change. Not improve, not simplify — not change. People were tracking a medical recovery in this app and a surprise is worse than an imperfection. So we migrated screen by screen, lowest-risk first, and verified each one against the behaviour of the live app rather than against the spec — because an app running for seven years does a hundred things nobody ever wrote down. I chose the architecture, Bloc with Clean Architecture, and built the tracking features, reminders and the health-platform integrations across HealthKit, Health Connect and Samsung Health. Crash-free sessions rose from 65% to 98%. The install dropped from 150MB to 60MB. Two codebases became one, and shipping a change stopped meaning writing it twice. One thing I’d do differently: our staged 1% rollout didn’t account for the health-platform integrations raising the minimum OS version, which cost about 6–8% of users their health sync until we caught it. Stage by OS version, not just by percentage.

Cover image for Ticket Tribe — a social
Ticket Tribe — a social network built around event tickets Instagram, but the posts are events and tickets. Discover a match or a concert, buy a seat, collect the ticket, post about it, and talk to the people going. Android and iOS, built from scratch, by one engineer. I was the only mobile developer on it for six to eight months and worked directly with the client on requirements rather than from a finished spec. The architecture is local-first — optimistic actions, an ordered mutation queue, idempotent retries and conflict resolution — because people use an app like this in a stadium, on a crowded network, and an action that silently fails in that moment is the one that loses you the user. On top of that: a community chat with voice messages, event discovery on Google Maps, and a WebView seatselection flow handed off to native. I wrote it test-first from day one, pasting real Postman responses into fake repositories as expected results — which is how most of the backend-to-UI mismatches got caught before they reached a screen. Delivered at roughly 80%. The client’s funding stopped before release, so it never reached either store

Cover image for Video Recorder 480p I created a
Video Recorder 480p I created a simple mobile app for recording on wide angle with low possible size of file so now I can record even 10 minute video for about 190 MB only while before it was taking at least 500 + MB or even GB for more file length. Built-in camera recorder does not allow 480p and standard quality and they forced to record on 720p and 1080p. I don't need that because most of my recording is done with front camera and back camera and that's all I needed. So finally my own simple mobile app to solve a real world challenge and now I don't need to rely on ads and get distracted. If you need help developing your mobile app, contact me.

Cover image for I tried a lot, but
I tried a lot, but I couldn't find any writing tool that would allow me to write easily and quickly, not even a single mobile app. I don't know why people are so obsessed with creating complex apps. The real problem remains that why doesn't any developer understand the importance of solving someone's problem? Now I had to create a simple, instant, anytime writing app and now my problem is solved. I can write in Urdu and English at any time and it is also saved in a folder and I can easily copy to the computer. That means it's easy for me to back up, otherwise when I was installing many android apps, they won't allow me copy data easily. I've solved my problem. No more ads, no more data stealing, simple and safe! If anyone need help for developing simple apps, just contact me. Note: I don't work with database on mobile apps as of now. However I work with database on web applications (php/mysl)

Cover image for A custom web-based system was
A custom web-based system was created for managing YouTube videos, captions, and auto-play with a timer. The project began from scratch with a single HTML text file containing a basic timer and was expanded over time through 100+ development phases into a complete, scalable platform. Built with PHP/MySQL and AJAX/jQuery, the system supports multiple user logins for managing operations seamlessly. Additional modules included a custom quiz system, live timer, and advanced features, all structured with clear, well-commented code. This made it simple for the client to maintain and update with only basic knowledge of HTML, CSS, and JavaScript. The result was a robust, user-friendly platform that grew organically from a simple idea into a full-scale management system, successfully running for a client in the USA.

Cover image for Successfully installed and integrated Linux
Successfully installed and integrated Linux with a different hard disc on a system of Windows with a different SSD. Both are physically separate but joined together in a single laptop. Mighty Power House of two operating systems. Now I can work with two operating systems and copy their data here and there and not only this, I can also play games by switching any operating system, directly from Linux to steam or Windows to steam. Further experiments remain.
