At Justech, I develop and maintain production applications with C#, ASP.NET Core, Entity Framework Core, and SQL Server or MariaDB. I’ve stabilized inherited systems and resolved performance bottlenecks, reducing response times from over 30 seconds to under 10 seconds.
For Al-Fikr, I redesigned large-document delivery around chunked streaming and progressive rendering, bringing perceived loading time down from minutes to seconds. I also integrated Apache Solr for full-text search and added Excel import and export.
I rebuilt Certigo as a reusable document-generation microservice, with a template editor, documented REST APIs, and QR-based certificate verification. I’m currently building this service for use across internal applications.
At the Faculty of Sciences of Monastir, I teach Web Development Fundamentals and Database Administration. I also handle production server administration at Justech, including deployment, database backups, and IIS and Nginx configuration.
