Custom software for businesses that don’t have a tech team.

Hi, I’m Justin. I design and build custom software for online businesses, professional service firms, and independent operators who need something built and don’t have engineers to build it.

Most small businesses run on a tangle of spreadsheets, email threads, and off-the-shelf software that almost fits but never quite. I learn how your business actually works, then I build the tool that takes the friction away. The cost and timeline look more like one person than a five-person agency.

I use modern AI tools as part of the build process. Power tools, not magic wand. It’s why a single person can deliver at the speed and price I do.

What I build. Internal tools, order management systems, customer-facing web apps, workflow automation, integrations between the tools you already use, custom analytics, and a lot of things that don’t fit neatly in any category.

How to work with me. Send me an email at hello@iamjust.in. Tell me about your business and what’s slowing it down. If I’m the right person for the problem, I’ll come back with a scope and a quote. If I’m not, I’ll usually know who is.
