No personal project has any business using microservices, unless it's specifically as a learning toy. Use a monolith. Monoliths can scale more than you can (provided you manage not to limit yourself to the single-thread single-process version of a monolith). Microservices are an organisational tool for when you need to release chunks independently.

I first wrote a program which ran on a web server about 25 years ago. In that time, computers have experienced about ten doublings of Moore's law, i.e. are now over a thousand times faster. Computers are very fast if you let them be.
