I build iOS and Android apps that pass App Review and keep working after launch.
Five years shipping production mobile apps in Flutter and Kotlin, for teams in Pakistan, the UK and the UAE. Most client work is one of three things: building a cross-platform app from requirements through release, taking over an unstable codebase and making it reliable, or adding real-time and AI features to an app that already has users.
Alongside that I ship my own products. Five iOS applications released in 2026, each one built and taken through App Review by me as the only engineer — listed below with store links, so you can open them rather than read about them. I also maintain browser-execution-runtime, a provider-agnostic browser execution runtime for AI agents, in TypeScript.

Built end to end as the only engineer: architecture, implementation, and App Review.
| App | What it does | Notable engineering |
|---|---|---|
| AI Receipt Scanner & Tracker | Turns photographed receipts into export-ready Excel and PDF reports, by category, month, client, project or tax purpose | Structured extraction from unstructured photos via a Supabase edge function; three report templates; credit metering across client and server |
| Voice Calorie Counter AI | Log a meal by speaking it, instead of searching and tapping | Speech-to-log pipeline with transcript confirmation; on-device OCR of packaged nutrition panels; home-screen widget |
| AI Humaniser — Detect & Rewrite | Reads a draft for machine-written patterns and rewrites it, with a compare view before you copy | Four-tier entitlement model with per-tier character caps, kept in sync between the Dart client and a Supabase edge function |
| Cluster — Shared Tasks & Chores | Shared chores and shopping for a household, with recurring tasks that rotate between members | Realtime shared sessions — several people patching one list at once; rotation queue; Siri manifest sync; home-screen widget with actions |
| Bloom — Voice Journal & Diary | Spoken journalling with transcription, mood tracking and a weekly written-back story | Usable with no account and no sign-up; sync is opt-in rather than the price of entry |
Oct 2025 – Present · Full-time · Lahore, Pakistan · Hybrid
Inherited a poorly structured Flutter codebase with memory leaks, excessive API calls and no proper state management. Refactored all major modules using Clean Architecture and BLoC, rebuilt the UI, and fixed the core performance bottlenecks. App performance and stability improved by 70% within four weeks.
Also integrated a chatbot layer and worked with backend engineers to fix the delivery assignment flow.

Volunteering — mentored students in Flutter and Kotlin at a local coding bootcamp (2022). Organised events, workshops and coding challenges with the ACM Society at UET (2018–2021).
The client figures — 70% performance and stability, 10 minutes to 30 seconds, 70% of queries automated — are from engagements that are not public, so you cannot audit them from outside. Treat them as my account of my own work. The App Store and repository links are the opposite: Apple and GitHub host those, and they hold up without you having to believe me. There is a fuller version of this distinction, claim by claim, at shahryarahmad.com/proof.
