Senior .NET Backend Architect · Open-Source Developer · Distributed Systems Engineer
Reliable backend systems are designed, scaled, and optimized with a strong focus on performance, maintainability, and clean architecture.
Distributed platforms, streaming systems, enterprise APIs, and reusable .NET libraries are delivered across fintech, telecom, education, e-government, healthcare, and developer tooling domains.
Senior .NET Backend / Full-Stack Developer with around 20+ years of experience, currently based in Muscat, Oman. Active open-source contributor with 1,099+ commits.
Production systems have been built from early Delphi and .NET 1.0-era applications through modern .NET 8/9/10, ASP.NET Core, microservices, event-driven architecture, and high-throughput streaming platforms.
Current work is focused on ABP-based higher education platforms at Asl Al-Uroba, including SDK infrastructure, admissions systems, and college admission workflows.
Relocation opportunities are actively being explored for senior backend/platform roles in Australia, New Zealand, Sweden, and the Netherlands.
