Need a well-structured relational database or reliable SQL solution for your application?

I can help with database design, database normalization, SQL development, database improvement, query troubleshooting, and database-related problem solving.

My practical database experience includes significant work with MariaDB and SQL, as well as MySQL/XAMPP and Microsoft SQL Server, together with earlier experience with Oracle and Microsoft Access.

At Mohammad Ali Jinnah University (MAJU), I designed databases in MariaDB for multiple academic and administrative systems, including course catalogue, fee collection, attendance, quality enhancement, programme degrees, admissions, examination admit cards, and daily class attendance systems. These projects also involved SQL and application integration.

I also worked with MySQL, PHP and XAMPP at MATZ Solutions, where database design was part of the development of an Inventory Management System for more than 47 Technical Institutes and a School Management System.

Earlier professional experience includes substantial Microsoft SQL Server database work, including database modelling and development for the Zultec ERP System, SQL Server administration, database security, backup and restoration, stored procedures, and extensive SQL development. Therefore, this service is not limited to a particular database product. The database technology can be selected or accommodated according to the client's existing application, requirements, and technical environment.

My experience spans different generations and types of relational database environments. The objective is therefore not simply to work with one particular database product, but to provide a properly designed relational database and effective SQL solution suited to the client's application and requirements.
