This is a follow up to the article I created in 2021 50 Cool Web And Mobile Project Ideas for 2021. My tech stack has changed slightly since then. I will only use it as an example so that you can figure out how you could possibly build these applications with your own technical stack. Each project has a programming level of either beginner, intermediate or advanced. These applications can be created using front-end, back-end or full-stack skills.

These are only examples and nothing is set in stone. In a real world case you would be expected to justify the best use cases for having an SQL or NoSQL back-end for example. And as for the programming levels this is just my personal opinion everyone is different so make your own judgements. I have included a basic brief for what the application can do. Of course I am sure that you can think of more ways to increase the feature list so go ahead.

Some of these applications can be monetised and used as a IaaS, PaaS or SaaS. Check out this article to learn what they are https://www.ibm.com/cloud/learn/iaas-paas-saas and how you can apply them to your projects.

My current technical stack is:

Front-End: HTML, CSS, JavaScript, TypeScript, React, React Native, Redux

Back-End: Python, C#, NodeJS, SQL, NoSQL, Docker

Instead of building a simple expense tracker you could develop a really complex one that not only shows your expenses but other peoples expenses too. I think it would be a great way to see how everyone is managing their lives. In terms of privacy it does not need to show incomes and how much you are spending. An alternative would be to just show what you usually spend money on.

So for example, clothes, tech, food, gym, pets, bills etc... It could potentially help people who are bad with their finances so trends so that they spend more wisely. And if you see how much better other people are doing you are likely to be more motivated to follow.
