Co-founder of INFLU · Engineer · London
I'm George Wall. I co-founded INFLU, a fashion intelligence platform, helped collaborate on Dansu, ship my own iOS apps, and write .NET analysers with 283,359 downloads on NuGet.
Ventures
I co-founded INFLU, a fashion intelligence platform, and I helped collaborate on Dansu, premium quick-dry towels for raves, gym and travel. Both are live, and I work on them end to end.
INFLU is a fashion intelligence platform. It scores looks as they start to rise, so you can see what is about to take off. I co-founded it and build the live product, including the Style Index and the scoring UI.
Dansu makes premium quick-dry towels for raves, gym and travel. I helped collaborate on the brand site and Shopify storefront.
iOS apps
3 apps live, 2 more in TestFlight or private builds. I design them, write every line, make the store art and handle the releases myself.
iOS game · Match-3 puzzle
Live on the App Store v2.5.2
My cosy match-3 game. Five magical worlds, a garden to bring back to life, a daily star board, Relic Runs and power gems that properly go off. No ads, and the core puzzles play offline.
iOS game · Space roguelite
Live on the App Store v1.2.1
A solo tactical space roguelite for iPhone and iPad. Each Frontier Run is a route through dangerous sectors: read the enemy's intent, build module combos, outplay rival commanders, then push deeper or extract with the salvage.
iOS app · Sober tracker
Live on the App Store v1.9.0
A private sobriety companion. A day count that rises over the horizon, a free craving SOS with guided breathing, a plan for hard nights and a journal that stays on your device. A slip is handled with support rather than a lecture.
In the lab
TestFlight build 23
A TestFlight recovery companion built around guided body scans, mood palettes and an on-device chat. Conversations stay on the phone; private progress can sync through the user’s own iCloud account.
Private build Playable build
A one-screen transit puzzle with generated levels, accessible gameplay actions and a heavily tested rules engine. Load matching passengers before the station locks itself solid.
Developer tools
Roslyn analysers, source generators and CLIs that catch production bugs while the code is still in the editor. 283,359 downloads on NuGet so far.
Compile-time safety · EF Core
A Roslyn analyser for expensive EF Core query shapes. It catches N+1 queries, client-side evaluation and early materialisation while the code is still in the editor.
Writing
Short, practical notes on production bugs: why tests miss them, and the tools I build to catch them earlier.
About
I’m George. I’ve spent more than ten years building software in London fintech: C# engines that price pension liabilities, Kafka services, and frontends built from scratch with React and TypeScript. When the numbers involve people’s pensions, correctness is not optional. That has shaped the rest of my work.
I like working across the stack. That might mean the Kafka consumer, the C# calculation engine, the React grid on top, or a SwiftUI app I take all the way through App Store review. I also build the bits that stop mistakes repeating: analysers, source generators and migration tools.
These days I also build companies. I co-founded INFLU, a fashion intelligence platform, and I helped collaborate on Dansu, premium quick-dry towels for raves, gym and travel.
I’d rather catch a mistake in the editor than explain it in production.
