MeteorJS + React JS Website Upgrade its packages, build a file uploader, migrate images to AWS-S3

Hi there, I have a website developed on MeteorJS + React JS; I need your help to 1. Upgrade it to latest meteorJS with reactJS's 2. Replace its existing routing to latest use React’s in-build SSR functionality 3. Develop a working custom JS file uploader (or use a plugin) to replace existing filestack one, it should deliver same functional as filestack one. (Currently filestack is handling all the images, every image you see in the site [login to view URL] are hosted on the it, it handles thumbnails, CDN, image compression etc for now.) 3.a. the same website also has another file uploader I have build long ago and it uploads file directly into AWS-S3, I use it for non images uploads 3.b. Your new uploader should have crop, image-rotate, thumbnail option, similarly to filestack’s one 4. Migrate all the images currently hosted in filestack to AWS s3, I wish to use AWS's CDN for it and delete filestack going forward What I can provide to you - Existing code - Can do a short call or doc to explain how existing code works, so your onboarding is quicker Expected outcome - A working code that’s easily to install, run and easy to deploy - All old images fully migrated into AWS-S3 so I don’t need file stack anymore and so I can delete it Steps to review existing file uploader 1. Go to the site [login to view URL] 2. Signup to it 3. Visit MyProperties from the main menu 4. Click on “Add property” 5. At the bottom of the form, click on “Add images” 6. You will see existing file uploader For point 1 and 2 -> Its currently using a custom modified version of FlowRouter to provide SSR, I developed that code couple of years ago and it’s outdated now. I believe this shouldn’t be a huge task as meteorJS along with reactJS now by default supports SSR. For point 3 and 4 -> I am looking for someone with filestack and AWS -S3 experience Skills/ Experience needed: SSR knowledge, ReachJS Experience, Meteor JS, meteor mup, mongoDB; Any previous project you have done with this skills.
