About

I'm Robbie Hickey. You work directly with me.

I'm a staff software engineer based in Fort Worth, Texas. Nullable Systems is my independent practice for focused web and software projects. I take on a limited number of engagements and remain responsible from the first conversation through launch.

Experience

Senior engineering discipline without enterprise overhead.

I have spent my career designing and shipping production software, including integrations, data-intensive applications, architecture, reliability, and technical leadership. I bring that planning and ownership to small-business projects without account managers or unnecessary process.

The name

Why “Nullable”?

In software, nullable means the value may not be known yet. Most useful projects begin the same way: the problem is real, but the right shape is not obvious. Nullable Systems turns that uncertainty into a clear decision and a working result.

What should work better?

Send the current site, workflow, or rough idea. I will tell you whether it looks like a focused website, a systems problem, or something better solved with an existing product.
