New Way Now: KeyBank saves 400+ hours on deployments with Gemini CLI and Code Assist

*Featured in this video:* Azim Shaik, Lead Enterprise Architect, KeyBank *Executive summary:* KeyBank, a leading financial institution, needed to modernize legacy codebases and eliminate manual bottlenecks that slowed down development cycles. By adopting Gemini CLI and Gemini Code Assist, KeyBank transformed its software delivery process, reducing the time to move from ideation to proof of concept (POC) from months to just days. The bank is now saving 300-400 hours on internal deployment processes, allowing engineers to shift from repetitive manual tasks to more meaningful work. These tools have also mitigated risk by generating real-time documentation for legacy code and reducing release cycles through AI-augmented peer reviews. *Challenge:* As a regulated financial institution, KeyBank manages critical legacy code where outdated documentation presents a significant operational risk. If a system breaks without clear documentation, the time to recovery increases exponentially. Furthermore, developers were burdened by context switching, forced to navigate multiple external websites to find patterns for specific problems. Internal deployment processes were also hampered by a high number of manual steps that consumed hundreds of development hours, while the traditional ideation and prototyping phase for new features typically took a couple of months to complete. *Solution:* KeyBank chose to adopt Gemini CLI and Gemini Code Assist to automate these manual hurdles. The team implemented a framework around KeyBank’s internal manual processes, using Gemini CLI to handle tasks that previously required extensive human intervention. Developers now use Code Assist within their IDE to solve programming tasks and optimize code without switching between multiple browser tabs. The bank also uses Gemini CLI to analyze legacy code and generate detailed, up-to-date documentation, ensuring that the logic behind 30-year-old systems remains transparent and manageable as the code evolv
