Full Stack Web App Development with API

I am looking for an intelligent, pro-active full stack developer with lots of API experience and ability to create visually appealing web apps. I'm looking for quick turnarounds and ability to make a great UI/UX. I have an established company of 17 years and do training and consulting in Simpro, a CRM software. We want to build multiple apps to enhance the software by connecting it to other apps directly via the API and also building various data cleansers and calculators. Background • Simpro is a job management system used by various construction and service and repair companies. • These might be electricians, plumbers or A/C installers and repairers. • Simpro has a central catalogue that is an item list that is used to create quotes with a list of materials, create purchase orders to purchase the items for jobs, then order and use items from stock and invoice customers. • Over time the catalogue becomes bigger and bigger with many unwanted materials. • Some items are imported from CSV and have never been used before, while others may have been used once 5 years ago and will not be used again. **** This app should locate all the items that are not being used and not required and archive them. Eg. Clean up the catalogue so only useful items remain. Note: - Some of these databases may have 400k+ items so efficient database and API handling is essential with multi-thread and minimum calls with maximum data per call utilising pagination and large payloads will be required. Once the initial project is complete we have many more projects working with the same API that we would like completed. We are looking for efficient programming and then a visually appealing UI / UX once core functionality is demonstrated. *** Please ensure you read the attached document carefully as this has the full scope and requirements of the layout, data requirements, filtering and comparisons required for the App.
