title:Sacha Ayoun, internship with Amazon Web Services
---
Welcome back to Sacha who has returned from a three-months intership with the CodeGuru team at Amazon Web Services.
Amazon CodeGuru is a [set of publicly available developer tools](https://aws.amazon.com/codeguru/) that use machine learning to automatically review code for bugs and code quality and to suggest improvements.
While at AWS, Sacha developed a proof of concepts analysis for Java that could help reduce the number of false positives or reduce the search space in other kinds of analyses without compromising soundness. Having enjoyed his time at AWS, he is planning to return for a second intership with them next year.
