Engineers at FAANG companies are now using AI coding agents directly in production work, beginning every project with a solid technical design document and detailed system architecture. After design reviews and sprint planning, developers rely on AI for test-driven development by generating tests first and then building out features, which significantly accelerates coding without skipping documentation or oversight. This structured workflow has increased development speed by about 30%, with all code still passing multi-developer reviews and staging tests before being pushed to production.
