Presentation: Move Fast, Don’t Break Trust: Shipping Constantly with Humans and Beyond

Suhail Patel delivered a presentation titled "Move Fast, Don’t Break Trust: Shipping Constantly with Humans and Beyond" at QCon London. The talk focused on how Monzo structures its software engineering organization and technical stack to enable rapid, safe deployments. Patel discussed opinionated microservice abstractions, tenancy-based staging, static analysis checks, continuous profiling, and other internal platform components that empower engineers and AI systems to iterate quickly without compromising reliability.

Monzo's infrastructure spans thousands of microservices and uses Kubernetes, Cassandra, and Etcd. Patel's role as a Staff Engineer involves maintaining this complex system and investigating any anomalies. The presentation highlighted how development and deployment environments have evolved, with many organizations now seeking to become "AI-native." However, Patel noted that most regulated industries still face lengthy assessment and approval processes before any code can be written or implemented.

He argued that the time-consuming aspects of traditional development cycles are primarily due to the implementation phase rather than the planning. The advent of AI and LLMs has dramatically accelerated code generation, enabling engineers to iterate on multiple variations in parallel. This can significantly reduce the time required for iterations, potentially from days to minutes or hours.

Patel emphasized the importance of investing in backend technologies to automate mundane tasks, as this can greatly enhance developer productivity and ultimately drive business goals such as increasing the rate of productivity per engineer.
