Any summer project ideas to step-up my programming skills? I'm bored but also not very creative when it comes to projects.

A lot of new projects today involve cloud stuff, docker, or kubernetes in some form or another. I find it pretty valuable when there's someone new on the team and they are able to say they tried it a little as opposed to never having used it.

Try to write an emulator.

Head to devpost, pick a Hackathon. Pick one with a participation prize of a t shirt or similar for a bonus.

Find an open source project to contribute and get involved in.

Highly depends on your level and what do you want to work/improve on, give us more information about what you're aiming for :). Still take the comments above tho

@Lyniven Sorry for late answer I'm not here that often :D. Basically I've just finished first year of university so I have some experience in C and web development + javascript. I was thinking of doing something with node, basically learning it by making some interesting project :D.

@rasukto doesn't help me that much, dunno, like create a web server using C.
Make a mini CMS with node/express and PostgreSQL + mongo for the search ? Can be as complex as you want depending on your level
