Suggestions regarding dev project

Hi all, for a quick background, I graduated from a Tier 1 college this year. My offer got deferred and finally revoked. I have joined a wfh company for 40% of the previous package. Work here is not very hectic and I definitely want to switch from here in a year or so.

I think it's a good time for making a good personal project to learn new tech ( non circuital branch with not much dev experience). I was thinking of a full stack microservices based project in node as I have done a mern stack project before. I won't be able to make end to end from scratch.

Can someone suggest a resource, for eg any course, from where I can get theoretical as well as implementation knowledge. Or, if any other suggestions that would be appreciated.
