Enterprise architecture with .NET and C#
Software that runs. For 27 years.
Hi! I'm Ramsey Albayati, a senior software engineer and software architect from Germany — 27 years of enterprise business software: financial planning, group consolidation, business intelligence.
TournaEvent
My own SaaS product for tournament and club management in martial arts — federation standard at the German JKA Karate Federation.
Remote-proven since 2015 — reliable across time zones
100% remote for a US-led team; German and US citizenship.
Current project
From .NET Framework 4.6 to .NET 10 — 79 projects, around 640,000 lines of C#
A long-lived codebase, live operations, no big bang: domain-driven design, CQRS, and plugin architecture as the way out of legacy.
