Redsign Qlik Sense Sales Analysis App

With a goal of identifying sales trends and patterns, I need an expert to redevelop a Qlik Sense application that I wrote myself a few years ago. This app has a heavy focus on product sales data sourced from a POS system, hence experience with POS data models would help

Key features required:
- Interactive Dashboards: Being able to interact with data is crucial. Dashboards should provide real-time results and be easy to understand.
- Advanced Filtering and Drill-Down Functionality: I want to be able to get very specific with the data examined and to dive deep into individual product sales details.

Sales by location yesterday vs same day previous week (filterable by location and including the total sales)
Sales by Location, Yesterday vs same day last year (correct day of the week, not the same date)
Sales by location week to date vs last week
Sales by location week to date vs last year
Sales by location week to date vs last year like for like only (not including branches that weren't open last year)
Sales by location yesterday vs last year like for like only (not including branches that weren't open last year)


Skills and experience:
Ideal candidates should have extensive experience in:
- Developing Qlik Sense applications
- Working with sales data, particularly POS data
- Implementing interactive dashboards, data visualization and advanced filtering inside a Qlik Sense app.
