The Bubble Developer Certification is a new program introduced by Bubble to help agencies and companies vet talent and give developers a way to prove their expertise in using no-code tools. The certification covers advanced topics such as responsive design, database security, performance, and backend functionality, and requires passing an exam with 90 questions within three hours. The exam has multiple formats including multiple choice, fill-in-the-blank, and true or false questions, and offers a unique QR code certificate upon passing. The certification is valid for one year and includes two attempts within a three-month period if needed. To prepare, developers can use the Bubble Academy, manual, and community resources.
