SQL Database, Microsoft Access, Microsoft Excel

I worked in an accounting company where I created a Microsoft Access professional payroll program for our special needs and every month for the next 20 years more than a hundred companies and more than 5000 workers were successfully distributed their salary and all the necessary accompanying reports. In addition, for the needs of my company, I created many other auxiliary programs that are still used today. I used the experience from accounting for greater application in relational databases such as SQL Server.
