Capital One's internal development pipeline is extensive and complex due to compliance and scale, involving over 8,000 engineers. The company has developed custom tools and platforms using various third-party resources such as Jenkins, Ansible, Groovy, Python, and Go. Despite the flexibility offered by these tools, the developer experience can be challenging due to fragmented systems and a lack of cohesive collaboration tools. The integration of AI into these systems poses significant security and compliance concerns, leading the company to consider moving back to on-prem solutions for certain tasks while continuing to utilize cloud services like AWS. A more unified developer experience is essential, with tools that streamline compliance, make collaboration easier, and integrate AI responsibly being critical in the coming years.
