The team

One person building Tech Professor. No team page theater — just me, and why I started.

Back to purpose

Why I built this

I felt myself drifting into brain fog

Agents took over more of the drafting. Shipping got easier. Staying sharp did not.

I built Tech Professor because I could feel myself slipping out of the loop. Agents write faster than I review. I wanted a way to stay in the loop — to keep improving, learning, and challenging myself.

That, to me, is the most important thing for staying relevant as an engineer while agents keep getting better. The tools improve at a rapid pace. They are not perfect machines. They make mistakes. Those mistakes are for humans to catch.

But if an agent writes the code and builds the tests, how do I keep up enough to tell it when it got something wrong? How do I improve so I can steer it better?

The other bottleneck

Review and learning are the slow part now

Code review is becoming the choke point. Learning and giving feedback are too.

So the second motivation is simple: how do we make understanding systems more engaging, while also sparking new ideas and concepts — instead of treating review as a grind you race through?

My goal for Tech Professor is to push on both fronts: keep honing my skills, and shrink the bottleneck for understanding systems.
