Cloud based software for analytics -- 2

I am building a cloud based analytics software. The software pulls data from salesforce Hubspot, Fresh Sales, Snowflake and MixPanel and presents it in form of charts and graphs. I need a software developer to build it from figma design I have built. I want you to create a software like figma designs: [login to view URL] First I want to sent data from Salesforce, Hubspot fresh sales, Snowflake, Mixpanel to AWS S3 bucket. Here you have to create some kind of scheduler to send data on regular basis. Send the daily data in the night time (Keep the clock according to user’s location, as some of my teams are in different timezone). Second make an API call to AWS lambda. This will process the data. Processing will take sometime, so you have to create some kind of scheduler to check whether the processing is completed (after processing is completed data is stored in S3 bucket, so the scheduler can check for if file is there or not) Third if file (the format will be mostly json here) is there, then fetch that file and extract the values and present on the dashboards (the figma designs). Create a login system as shown in the designs. This should be easy to scale. Initially I need 30-40 accounts but I might need to increase number of account to 200-300 soon, so keep that mind. The account information like name of user, team name will be used for fetching the data as data shown to each individual can be different. You can add your own creativity wherever you will feel necessary, but tell me know before you do. Don’t use PHP framework for backend. I prefer python framework for backend but I am ok with Java/C++ framework also.
