We build software and media that earn quietly, every month.
ShellRick Tech is a small, independent studio building subscription software and ad-supported digital media, with limited technical consulting for the right projects.
We run a small portfolio of products rather than chasing one big bet, and we keep each one simple enough to maintain properly over the long run. That means subscription tools people actually pay to keep using, free ad-supported sites that earn their place through genuine usefulness, and technical consulting we only take on when we have the capacity to do it well.

From the blog
Thoughts on building software and learning by doing.
Why We Don't Chase Every Feature Request We Get
Every feature request is a real person telling you something true about their day. That doesn't mean every request belongs in the product. Here's how we sort the two.
What a Technical Due Diligence Engagement With Us Actually Looks Like
Most technical due diligence requests come in vague: "can you look at the codebase." Here's what we actually do once someone hires us for one, step by step.
The Point Where a Side Project Stops Being a Side Project
Nobody tells you when a side project turns into a second job. We missed the point where it happened to us, and only noticed it looking backward.
