I’m Joe, founder and principal engineer at Jiss Tech. I build custom software, CRMs, APIs, automation, and web and mobile products from Bayonne, New Jersey.
My work spans the interface, the services behind it, and the realities of running it. The case studies here show the decisions as well as the finished screens.
TypeScript / React / Node.js / Python / PostgreSQL / Docker
Start with the workflow, the people using it, and what a useful outcome would look like.
Agree on scope, work through the key decisions, and make the important parts reviewable.
Connect the experience to the system behind it, then refine it against real use.
Tell me what you’re building—or what needs to work better.
