Hey, I personally recommend smaller platforms, I'm not a native English speaker, so the platforms I use will probably be useless to you, but I can distinguish a few key points: Keep it small, companies that go niche platforms probably aren't looking for 1000 applicants. Look for human written posts, that actually tell you something about them, instead of classic "we provide complex solutions for big companies, that provide services to other big companies". Look for direct contacts, like a phone number or an email address, so you can engage in a real human interaction sooner and speak for yourself, instead of letting people judge you based on a resume, that might have some minor flaws.

Check the communities, like reddit, telegram/whatsapp groups, HN, etc. Again, direct communication can do wonders.

Check companies websites, most tech companies have a dedicated Careers page with all the open positions and requirements, write them a personal email and wait for the response. This can give an extra karma point, because you didn't find them on some hiring website while looking for a job, you've found this position on their website, so it already tells them something about you wanting to work there.

If you are interested in startups, you can check some Y Combinator reports/news, or look at some producthunt posts, it's a riskier bet, but if you are into that kind of a thing, can be a great path.

Hope this can be helpful, best of luck with your searches!
