What I'm looking for

I'm looking to keep building reliable backend systems, APIs, and event-driven services where I can contribute to production releases, collaborate with product stakeholders, and grow through strong engineering practices.

At Oasis Computer Systems, I build and extend backend services for a live multi-tenant leasing SaaS used by enterprise finance clients in Saudi Arabia, including Abdul Latif Jameel Finance and Dar Al-Etiman. I work on sales and finance APIs covering invoices, inventory, transactions, broker integrations, and payment flows.

I use ASP.NET Core, SQL Server, Entity Framework Core, RabbitMQ, MassTransit, Redis, and Hangfire to deliver reliable production systems. I ship through Azure DevOps CI/CD pipelines and work closely with stakeholders through Agile delivery, code reviews, automated tests, logging, and diagnostics.
