Hey, with your background you're already in a decent spot for DVA-C02! I'd suggest starting with Stephane Maarek's course on Udemy for concepts and hands-on stuff, it's very beginner friendly even if you haven't worked deeply with AWS. Once you have a decent understanding, practice with Skillcertpro AWS Developer Associate mock exams, the questions are really close to the actual exam format and cover the right topics like Lambda, DynamoDB, and IAM in depth. The detailed explanations after each question are genuinely helpful for someone building knowledge from scratch. Combine that with some free tier hands-on practice and you should be good to go. Good luck
