Presentations
Maintaining large-scale distributed systems poses significant challenges due to their complexity, scale, and the risks of live changes. This talk presents a case study of a system which processes vast volumes of items in real time for billions of users. Over nine months, this system underwent a live architectural refactoring to improve maintainability, developer efficiency, and reliability. Key strategies included staged rollouts, automated testing, and impact validation, resulting in a 42% boost in developer efficiency, 87% reliability improvement, and notable gains in system performance and resource savings.
Looking forward, in this talk, we will explore the growing role of AI-driven refactoring techniques in accelerating development, enhancing reliability, and optimising performance in complex systems. This talk offers an overview of our current efforts, practical insights, and future directors for code maintenance and refactoring empowered by AI.
