About

I am a . NET Backend Developer and Software Architect with over 8 years of experience designing scalable APIs, distributed systems, and enterprise backends across fintech, enterprise, and retail domains. Most recently at KamelPay, I contributed to backend modules and production support for a live digital payments platform while currently architecting a multi-tenant inventory platform using . NET 10 REST API and MAUI. My work spans . NET Core, . NET 10, ASP.NET MVC, C#, RabbitMQ messaging, SQL Server, PostgreSQL, and cross-platform . NET MAUI development. I have built multi-step KYC onboarding systems, event-driven notification services, ETL pipelines, and enterprise CRM applications, applying Onion Architecture, SOLID principles, and clean code design throughout. I also mentor junior developers and optimize database performance for transaction-heavy fintech endpoints.
