Amazon Q Developer coding assistant for IT developers
Techcombank scaled Amazon Q Developer from 50 to about 600 developers and estimated 572 days of work saved on its mobile app in three months
Problem
Techcombank, one of Vietnam's largest private banks, wanted its developers to ship features for its mobile app faster.
Approach
The bank ran a trial with 50 developers on Amazon Q Developer, a generative AI coding assistant from Amazon Web Services, then extended it to about 600 IT developers. Features used on the Techcombank Mobile app included code suggestions, code fixing and explanation, and AI-written commit messages. The bank said it planned to extend the tool to all developers in 2025.
Results
Takeaway
Developers accepted about a third of feature suggestions and nine in ten documentation suggestions. The bank estimated a 30% productivity gain from days saved but did not explain its calculation.
