Hi! I’m Kevin Renskers, a product & engineering lead.
I take software from a vague idea to a product people actually enjoy using. Twenty-five years in, what I care about isn’t the framework of the week, it’s making the right product and technical decisions and building things that still make sense a year later. I thrive at the intersection of product and engineering: helping decide what’s worth building, shaping the UX together with design, guiding the architecture, mentoring the team, and staying hands-on in the code.
I’ve fixed, finished, and shipped software for international clients such as Last.fm, Sentry, WeTransfer, and Unilever. I’ve also built Critical Notes and RSS Filter, from first idea to running product.
On this site you’ll find my technical writing, open-source work, and more about working with me.
