Looking for a side project that could solve a real world problem.

Hello, I am a Belgian Backend Developer currently working at Fintech startup focusing on the sustainable heat market. Me and 4 coworkers (including 2 co-owners) do all the development work, together we are building a SaaS platform and already have international clients. I myself am a backend developer with knowledge of frontend (I prefer backend).

To deliver our service we are using the Microsofts Azure platform, a platform I grew quite comfortable with and am expanding my knowledge of each day.

The technologies I use on a daily basis are the following.
• .NET Core
• APS.NET Core
• CosmosDB/ MongoDB, I know SQL but if prefer non SQL solutions
• Azure functions
• CQRS/MediatR
• Etc.

I think the future lies in progressive web apps and I like to contribute to well thought of side project that could solve a real world problem.
