Refactoring thousands of files to break a client-side monolith is a daunting task, but when our estimation for extracting the client side monolith hit the 8-year mark, we knew manual refactoring wasn't an option, so we built an AI infrastructure engine that is currently compressing that timeline to just 6 months
This isn't a theoretical proposal, we are currently midway through the process, successfully migrating production code daily and compressing that timeline to just 6 months. In this talk, we'll explore the custom orchestration engine driving this reality, while you will walk away understanding how to combine the deterministic reliability of ASTs with the creative power of LLMs to solve your own "impossible" legacy migrations.
