How can I promote my projects?

Hi, I’m 16 and want to become an Electrical & Electronics Engineer and inventor to build prototypes that solve real problems.

I’ve developed projects before and joined to project competition, but my team didn’t work well, so we lost. Now, I’m working alone on new projects, but I don’t know how to share them with people, find support, or choose the right competitions.

I Need Advice On:

• How can I effectively showcase my projects to get feedback and support? -Where should I share them (online or offline)? -Should I join competitions like Teknofest, ISEF, Genius Olympiad now, or finish prototypes first?

-How can I find people or mentors interested in technology to avoid working alone?
