What Leaders Say

A track record built on trust, craft, and results, from Fortune 500 to startups.

I had the pleasure of working with Michael at the AWS Generative AI Innovation Center, where he made valuable contributions to AI test and evaluation frameworks and a CI/CD deployment pipeline using GitHub Actions and AWS CodePipeline. His work helped automate the deployment and execution of evaluation processes, making it easier to compare model behavior across versions and validate changes. Michael combines strong technical knowledge with a genuine willingness to help others.He is thoughtful, dedicated and dependable.He consistently made time to collaborate, share what he knew and work through complex technical challenges.Beyond his engineering abilities, he is simply a great person to work with.I recommend Michael without hesitation and would gladly work with him again.

I've worked with Michael for the past several years, first at AstraZeneca and most recently at Amazon, where he was a Software Development Engineer in the AWS Generative AI Innovation Center.He is one of the most knowledgeable AI engineers I've encountered in my career. He is always on the cutting edge of the field and, just as importantly, always eager to help others learn it too.At AstraZeneca, Michael was part of the team that led the introduction of RAG(Retrieval- Augmented Generation) system development to the organization, pairing deep technical expertise with the vision and communication skills needed to bring a new technology into a large enterprise.At Amazon, he applied that same expertise to helping enterprises build and deploy generative AI solutions.On top of all that, Michael is friendly, personable, and a genuine pleasure to work with.I highly recommend him to any organization looking for an engineer at the forefront of AI.
