As a skilled mathematician, developer, and data analyst, I possess an exceptional command over MS Excel and Access, making me an ideal fit for this project. I've developed numerous databases with varying levels of complexity over my seven years of experience in the field with my most recent clients being in sales. This hands-on familiarity with sales data vastly enhances my understanding of your business's requirements.
Moreover, I am well-versed in SQL queries, data storage and management, as well as implementing user-access controls to restrict visibility based on roles. This intricate understanding dovetails perfectly with your needs as outlined in the project description. In addition, having coded in VBA, C, Java, FoxPro among other languages gives me an edge when integrating systems like Access with Excel.
My fluency in English and native Russian along with intermediate Hebrew allows us to communicate seamlessly, breaking any potential language barriers. Lastly, I want to emphasize my ability to create user-friendly interfaces and my knack for generating custom reports - skills that will greatly enhance your sales data management process.
