Python is very flexible and definitely up the job (although, in reality, any language will be able to cope with this task!). Python has some good libraries built in, and also some third party libraries that will help here. 1. Convert CSV -> JSON 2. Validate against a schema 3. Deploy to AWS

1. The builtins include json and csv libraries, and, depending on the complexity of the csv file, it is fairly simple to convert:

import csv
import json

with open("your_input.csv", "r") as f:
    csv_as_dict = list(csv.DictReader(f))[0]

with open("your_output.json", "w") as f:
    json.dump(csv_as_dict, f)

1. The validation part is handled nicely by this library: https://pypi.org/project/jsonschema/ It allows you to create a schema and check whether what you have created works for what you want to do. It is based on the json schema standard, allowing annotation and validation of any json

2. It as an AWS library to automate the upload - or in fact do pretty much anything with AWS - from within your codebase: https://aws.amazon.com/sdk-for-python/ This will handle authentication to AWS and uploading / deploying the file to wherever it needs to go.

A lot depends on the last two pieces, but the converting itself is really pretty neat.

I would use Go. Since CSV files are flat (no hierarchy), you could use the encoding/csv package to read each row, and write out the values as JSON. See https://medium.com/@ankurraina/reading-a-simple-csv-in-go-36d7a269cecd. You just have to figure out in advance what the key is for each row.

This should be pretty doable in any language. Go with whatever you're most familiar with.

That being said, there's a case to be made for using Node.js since it's trivial to convert an object to JSON and vice versa.

I assume that you mean Flutter by Dart. I have over 6 years experience programming in Android SDK, but about 1,5 month in Flutter. So far I think that Flutter is the future for mobile development. Flutter SDK is much better designed. Ecosystem of libraries seems having much higher quality. I would even say that android opensource libs are having really poor quality. Many times I am wondering how can garbage like that have so many stars at GitHub. Android SDK is hard to compose so you reinvent even basic things on and on, which is totally different story at Flutter. Lolcycle? Both are having good documentation. I quess apps in Flutter can be done in 1/3 of time compared to develop AndroidSDK and iOS, its design is that much better and contemporary. As of language comparison - Kotlin is better, but the difference is not that important. Go from one language to other is no problem. Dart is being updated with new features.

I've selected Flutter and Dart for my side projects and never regretted. Dart learning curve is easy after any OOP language . Flutter as a framework is also has a low entry threshold. I've already started development after a week of learning. Pros for me: code can be build for Android and IOS devices (for ios you need mac or VM), apps written in Dart have great performance on each of these platforms, flexibility. Cons: if you want to build a product as a business and want to hire a new Flutter Developer in the future it can be a problem as the framework and language is not popular for the moment.

It depends on what is the purpose of your app development. Do you want to make one app that shares the codebase for both iOS and Android? If yes, then Dart is the way to go. Does your app include interacting with hardware features like camera, Bluetooth, if yes, then go for native Android for better performance? Dart is good for simpler UI apps where you just do basic crud operations over the network and show data but if you need richer UI experience go with native.

I have worked in mobile development since 2010. I have experienced myself on various techs including Native SDK (Android), React Native (from 2016) and Flutter (2018). Almost the apps nowadays can be built using cross-platforms frameworks like React Native or Flutter. I suggest you start with Flutter. Flutter SDK is designed well to speed up your development and it still keeps the quality for your apps. If you're familiar with OOP languages (Java, C#...), switching to Dart is really quick and easy. Of course, sometimes you will need to dive deep into native parts but almost the cases you don't need. Good luck!

Hey Muhamed, For web development, you'll have to learn how to write backend APIs and how to build UI for browsers, apps, etc. If you're just starting off with programming, I'd suggest you stick to one language and trying developing everything using it to cut the unnecessary learning overhead. Although Python and JavaScript are very similar for beginners, JavaScript is the only available option for both frontend and backend development for a web application. You can start working with Node.js for your API development and Vanilla JS along with HTML/CSS for UI. You'll only need to learn one language to do all of this. Hope this helps.

Flutter is good for everything and it is getting better as I am speaking. Flutter Web is almost ready for production and I have made 2 complex working websites already.

Well. Flutter is just a Framework (just like Django btw.) and it uses Dart as a programming language. Django is kind of solving a different problem than Dart. Dart is intened for use in Front End Applications and Django is a Framework for Back-End Web Development.

So if you want to program Flutter Apps (although i wouldn't recommend it for any serious web development yet since Flutter web isn't very mature yet) i would recommend you just lern Dart.

From a management and hiring perspective, I recommend Flutter (Dart). It provides native solutions to both mobile platform ( (Android and IOS) while having the same knowledge. Hiring managers look at this as an advantage since a developer can provide solutions for both platforms whit the same knowledge. The Flutter framework is growing and there is a lot of resources to ground your knowledge and start experimenting. Dart is also a great language that covers most E2E necessities, so again, no further need of learning one language for FE and another for BE and services. It is my belief that Dart will surpass Kotlin soon, and will leverage to Python and Java in the upcoming year.

If you are interested in Flutter, learn it on your own time, parallel to the course. No matter what order you do them, eventually you will end up learning them all anyway ;-)
