A UK software company for apps, websites and automation
MgonnacrushT Limited builds mobile apps, websites, n8n automations and the servers behind them for UK startups and small businesses. Solo founder, remote delivery, invoiced through the UK company.
The company
MgonnacrushT Limited is registered in England and Wales (Company No. 16877439). It is run by a solo founder, so the person scoping the work is the person building it. The company builds in-house products, including SaveT and City Line Map, and takes on client work for founders who need working software, not slide decks.
Technical scope includes Flutter and native Java Android apps, Java Spring Boot REST APIs, PostgreSQL, Linux VPS deployment with Docker, CI/CD, and Google Play publishing. Remote worldwide.
Alihan Ersoy, Director
I lead MgonnacrushT as Director. Most of my time goes into SaveT, City Line Map, and shipping client projects end to end, from architecture to store release.
Before founding MgonnacrushT, I spent three years as a Unity Developer Technical Support Engineer, helping developers integrate mobile services and take their apps and games through publishing on Huawei AppGallery.
I prefer small scopes, clear communication, and software you can actually use and hand over.

Product philosophy
MgonnacrushT builds software worth maintaining: clear UX, stable architecture, and room to improve after launch.
- Fix a real problem before adding features.
- Ship code you can hand over to someone else.
- Listen to users and adjust.
Privacy and trust
- Your data stays yours.
- Security and reliability belong in v1, not a later patch.
- Policies should be plain English, not legalese wallpaper.
