Who most likely is the speaker?

Despite such short notice, thank you for attending our new product review. The product development division is pleased to have the chance to brief you on our ambitious ongoing project. I’m Steven Hall and(89)I’m in charge of the design and development of our new computer, MX3000.(90)This computer is much faster than earlier models. Our team has been working to develop this product for over two years. A customer survey has yielded some encouraging results. Participants in the survey seem to like this new model. We have a tentative timeline for further product testing and release dates. Now, let me start my presentation with the advantages of the new model.(91)Please look at the first slide that shows its unique design.
