My name is Mathew Fleisch, and I am a Full Stack Developer from San Francisco. I love working on new projects and features; often times, this means fixing and retrofitting existing products first. Each development team I have worked for, from non-profits to Apple, all have a finite amount of resources, whether that is infrastructure or developer time. Throughout my career, I have adopted Larry Wall's philosophy and will automate as much as possible. If a task requires human input, I will create a tool that can allow someone closer to the data, to maintain it. This frees up developer time, to make new things, and reduces the amount of communication necessary to complete common tasks within the organization. In order to optimize limited resources, this philosophy has helped me in each of my roles to maximize my impact on the team. One of my current hobbies, testing out tools and techniques that hackers use to infiltrate systems and exfiltrate data, was sparked by working for the Black Hat security conference. Utilizing these skills has helped me to know what is possible, when using the latest best practices, to defend against all attack vectors. resume.pdf


Tools Developer


Working for a start-up means constantly adapting to shifting requirements, while making forward progress. I started in the back-end services team, and starting in November, I moved to DevOps as a tools developer. I have been able to create tools to automate business tasks and help to retrofit a young application to scale efficiently. Mostly writing node/javascript and I am starting to contribute to c#/dot-net codebase as well.

The Global Finance department at Apple created and maintained internal websites, to help facilitate secure communication and document sharing. The small team of developers primarily used LAMP Stack CodeIgniter, with some NodeJS/Grunt/Gulp/Sass optimization, for most projects, and Drupal CMS for others. Apart from other responsibilities, I wrote parallelized scripts to recover lost data for another team.
