i haven't used any platforms, i've found jobs through ads on social media and stuff. One agency/recruiting firm i can recommend is donestreet[0], did their interview process, they were able to get me in front of companies very very quickly, who were all basically ready to hire me. I found another opportunity and went with them. But I would contact donestreet if i ever needed to look for another job
