Summary

With over 30 years of daily coding experience, creating software is my passion. My expertise spans numerous platforms and languages. From 2009 to 2019, I served as Director of Technology & Chief Architect at Firefield, overseeing dozens of projects. Currently, I apply my skills as a Principal Software Engineer at LifeSpeak.

Skills

I consider myself a generalist software engineer. With over 30 years of experience, I have used a vast array of languages, frameworks, and tools. I don't define myself by a specific stack; instead, I focus on fundamental engineering principles and leverage the right tools for the job. My strength lies in my ability to adapt, learn new technologies rapidly, and solve complex problems regardless of the specific implementation details. If a project requires a technology I haven't used before, I learn it.
