About

I build backend systems that move money securely at scale.Currently a Software Engineer II at EJADA ( .NET developer ) , I am a core .NET backend developer on the Tarikat Inheritance System for Saudi Arabia's Ministry of Justice , a modular monolithic platform (ABP .NET 8, CQRS/MediatR, MySQL, Hangfire) handling 500+ daily financial transactions with 99%+ reliability, integrated with SAMA and CMA banking services. I was deployed on-site at MOJ HQ in Riyadh to support enterprise digital transformation and financial automation initiatives directly.My technical scope covers .NET 8, ASP.NET Core Web API, Entity Framework Core, LINQ, SQL Server, MySQL, and Hangfire background job orchestration. I specialize in query optimization (eliminated N+1 issues on 100K+ record datasets, reducing API latency by 40%), RESTful API design for regulated environments, and building resilient background processors for async financial workflows. I am an AWS Certified Developer – Associate (DVA-C02, 877/1000) with production serverless experience using AWS Lambda, API Gateway, DynamoDB, and S3.I work at the intersection of Clean Architecture, SOLID principles, and real-world financial compliance , turning complex inheritance and estate distribution workflows into scalable, testable, maintainable code. I thrive in Agile/Scrum teams where backend precision directly drives regulatory and business outcomes.Technologies I work with: C#, .NET 8, ASP.NET Core, Entity Framework Core, SQL Server, MySQL, MongoDB, CQRS, MediatR, ABP Framework, Hangfire, AWS Lambda, API Gateway, DynamoDB, S3, EC2, Docker, CI/CD, Azure DevOps, Git, Microservices, REST APIs, NUnit, xUnit, Swagger, OpenAPI, Agile, Scrum, FinTech, GovTech, Backend Development, Software Engineering.I am open to Software Engineer and Backend Engineer roles — remote, hybrid, or on-site in GCC, Europe, or North America. If you are building systems that need to process data or money securely and at scale, I would love to connect.📩 Feel free to message me about .NET backend, cloud-native, or full-stack opportunities.📧 mahmedaldosoky@gmail.com
