Cover image for Thesis Evaluation Management Designed and developed
Thesis Evaluation Management Designed and developed a database-backed web application for managing the thesis evaluation process at an academic institution. The system manages student and thesis information including registration number, degree/programme, thesis title, supervisor and co-supervisor. It also manages thesis submission according to prescribed templates and verification requirements, including formatting, plagiarism and other guidelines. Students who qualify proceed to thesis defense before a panel comprising the supervisor and internal and external members. The system maintains the status of the thesis through these stages and supports final publication after successful evaluation and prescribed formatting. My contribution: Database design and application development. Technology: MariaDB, C#, .NET Core, Entity Framework Core, ASP.NET (http://ASP.NET) Core Identity and RDL Reports.

Zultec Barcode Solutions — Barcode, PDA & WLAN-Based Business Solutions As Team Leader / Senior Software Engineer at Zultec, I designed and guided the development of mobile and barcode-based solutions connecting handheld PDAs, barcode scanning, WLAN/WiFi connectivity, applications, and enterprise databases. The solutions were developed using C# with Visual Studio 2005, .NET Compact Framework, Windows Mobile 6.0, WindowsCE, and SQL Server Mobile 2005, with integration with SQL Server and Oracle databases where required. I guided developers in implementing mobile applications on handheld devices and PDAs for a range of operational environments, including: • NJ Autos, Pirani Group — WiFi-based real-time transfer of workshop-floor data from handheld PDAs to SQL Server, with barcode scanning of engine and chassis information through quality checking and dispatch. • Yunus Textile Mills (YTM) — Barcode-based verification to prevent incorrect items from being packed and incorrect cartons from being dispatched. • Central Library System, NED University — Barcode generation and circulation for more than 65,000 books and 11,000 members, including issue, return and reservation using Oracle 10g and Oracle Forms/Reports. • Defense Central Library (DCL) — PDA-based physical stock taking to identify lost books, duplicate entries and uncounted inventory, with transfer of collected data to Oracle 10g. • Pakistan State Oil (PSO) — Barcode-based physical inventory of fixed assets to trace mislocated and lost items. • NSD — WiFi-based real-time data exchange through handheld PDAs across warehouses containing more than 300,000 inventory items, including barcode-based issue and return. This work combined mobile application development, barcode technology, PDA-based data capture, WLAN connectivity and database integration to support accurate and traceable operational processes across automotive, textile, education, library, oil & energy, and warehouse environments.
