Experience

SwiftAssess | Assessment Platform for Educational Institutions

An ASP.NET web application for educational assessments, serving the UAE Ministry of Education, universities, and private schools. The platform includes Web Forms, Web APIs, and Entity Framework, and I developed all the integrations with third-party systems to build a healthy ecosystem.

As a full-stack developer, I have played a key role in transforming and growing the application by adding many features, fixing existing features, providing technical and business feedback, and conducting training sessions for professional trainers and business meetings with clients. I have also provided continuous support to clients through the support team and prepared and deployed updates to clients' environments or the company's cloud.

SwiftAssess | SmartPaper Application

https://swiftassess.com/products/smartpaper

The SmartPaper app supports the main assessments platform. The solution is configured and customized for clients for each assessment and delivered offline. It uses a scanner application to process the scanned papers and sync the data online. I developed the entire product, which involved working with
WPF, HTML building, JSON manipulation, and image processing.
