Message

At 10Pearls, I design and develop enterprise applications with .NET 8, ASP.NET Core, and React. I architect microservices and event-driven systems using Kafka for inter-service communication and asynchronous processing.

I define OpenAPI (Swagger) contracts and use code generation to keep APIs consistent. I also deliver cXML integrations and optimize SQL Server and PostgreSQL queries for transactional operations.

At NETSOL Technologies Inc., I contributed to a finance and leasing ERP platform, refactored legacy components, and optimized database interactions. I also designed workflows for financial processes and mentored junior engineers.

Earlier, I developed healthcare applications at F3 Technologies Inc / Mobile Technologies Rawalpindi, and worked on Oracle reporting and ERP modules at Wilshire Labs. My work has included Docker, background processing, ETL pipelines, and unit testing.
