Map Based Web Application Architecture

I was recently hired by a startup that performs data analysis on agriculture groves and is looking to present it on a new web app. My role is to build a more scalable, modern system for the team. I have done a boatload of research and diagraming to reach a feasible starting point for fulfilling my task, but want some direct feedback on my chose of the tech stack/architecture.

Frontend:

• ReactJS with Typescript / Redux
• MapBox

Backend:

• NodeJS with Express as the server framework
• GraphQL API using AWS AppSync, chosen for its efficient data retrieval and ease of use compared to a RESTful API

Database:

• AWS Aurora for storing relational data
• AWS DynamoDB for storing unstructured JSON data
• AWS S3 for image data

Hosting

• Vite (fastest dev builds & bundling)
• AWS EC2 (deployment and running the machine learning models on the images)

I am looking to get some open-source feedback, as well as any pointers or alternatives that would fit better for our use case. Thank you in advance.
