# Girish Patel > Girish Patel is a UK software engineer with 22 years of commercial experience and 10 years of test-driven development, helping senior developers ship AI-generated code with confidence. ## Pages - [The method](https://girishbuilds.dev/method/): the signed-off plan, outside-in TDD, and mutation testing as a scope gate. - [The course](https://girishbuilds.dev/course/): practice material for running the method on your own codebase. Not yet released. - [Writing](https://girishbuilds.dev/writing/): notes and essays. ## Writing - [Use mutation testing to delete code, not to score tests](https://girishbuilds.dev/writing/mutation-testing-deletes-code/): An AI agent will happily write more than you asked for. Mutation testing, pointed at the right question, is how I take it back out.
