Skills & Experience in Tech

This website was designed, built and is hosted by me, Mike Cardwell. Web, DNS, email and all. Check out my projects and my blog posts for an idea of what I can do.

Following is a list of technologies that I have used to build, deploy, ship and manage different projects over my ~23 years in the IT industry. This list isn't exhaustive and I learn quickly. Perhaps you need somebody with my experience and skills? Contact me
