I've spent more than a decade turning customer needs into technical specs and delivering software slowly and steadily over many small iterations/deliverables. I've delivered software solutions as an individual, and as a member of small teams.

I have worked with various database systems, but spent the most time with MySQL. I have worked on desktop and web applications, but mostly web applications since ~2010.

I have experience with large web frameworks, but am comfortable building a toolbox out of composable libraries.
