Teemzo
An owned product that reflects how I approach narrow customer problems: learn the workflow, find the leverage point, and build the smallest useful system around it.

I help founders turn uncertain product ideas into software people can actually use.
Senior product and engineering judgment for early-stage teams that need to define the right thing, ship a credible first version, or rescue a build that has lost direction.

01 · Fit
The work is most valuable when the product is still ambiguous.
Good reasons to call
- You have a real product idea, but the first version is not clear.
- Your current prototype works poorly or proves the wrong thing.
- You need senior technical judgment without hiring a full team.
- You want to pressure-test scope before committing more money.
Probably not a fit
- You need a large agency, a fixed feature factory, or staff augmentation.
- The project has no owner who can make product decisions.
- You want a complete custom application built for $2,000.
- You need activity more than an honest answer.

I still build products, not just recommendations.

An owned product and ongoing proving ground for product strategy, application architecture, automation, and the unglamorous work required to keep software useful.

Product Definition Sprint
We use the time to remove the most expensive uncertainty around the product. The result is a concrete recommendation for what to build, what to defer, and what should happen next.
- Two working sessions with the people who own the problem
- Review of the idea, prototype, existing code, or current workflow
- Written scope for the smallest credible first version
- Technical approach, primary risks, and rough build range
- A direct go, revise, or stop recommendation
This is a definition engagement, not a $2,000 promise to build the whole product. Follow-on implementation is separate and typically billed at $200/hour.
Frame the problem
Get the real business constraint, customer, and decision on the table.
Reduce the scope
Separate the smallest proof from the features that can wait.
Choose the next move
Leave with a plan you can build with me, hand to another engineer, or decide not to pursue.
04 · Bobby
One accountable person, not a mystery team.
I’m Bobby Cavezza, a software engineering manager and startup founder. I work across product definition, architecture, and hands-on implementation, which means the recommendation and the code do not come from separate rooms.
I’m useful when a founder needs someone who can challenge the premise, make the tradeoffs explicit, and still get into the details.

The Self-Taught Developer’s Guide to Big O Notation
A practical guide to the performance ideas that often get buried under math-heavy explanations—written for working developers who learned by building.

Tell me what you are trying to build—and what is currently unclear.
A useful first note includes the customer, the problem, what exists today, and the decision you need to make. If the sprint is not the right next step, I will say so.
