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 who know their customer turn an idea or a prototype into software people can depend on.
You might have an idea, a spreadsheet, or a working prototype you built with AI. The next step is the same either way: get honest about the customer problem, cut the scope to the smallest useful version, build it properly, and find the architecture, security, and infrastructure risks while they are still cheap to fix.
Work shaped around the problem, not a preset package
Clear thinking before expensive code.
Product definitionScope the smallest version worth building
Hands-on engineeringPrototype, architecture, and implementation
Security & infrastructureCatch early risks before they become expensive
01 · Fit
The work is most valuable when the product is still ambiguous.
Good reasons to call
- You understand the customer better than anyone, but the first version is not clear.
- You built a prototype with AI and now need something you can put in front of paying customers.
- 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 the cheapest implementation without product involvement.
- You need activity more than an honest answer.

I still build products, not just recommendations.

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

Product and engineering partnership
We focus on the most important uncertainty or technical constraint in front of the business, then move from judgment into hands-on work when building is the right next step.
- Customer-problem and workflow validation
- Review of the idea, AI-built prototype, existing code, or current system
- Scope and priorities for the smallest useful product
- Architecture and hands-on implementation
- Early security and infrastructure risk review
Every engagement is scoped around the client, stage, and work. We align on the immediate problem, priorities, and working approach before starting.
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, startup founder, and hands-on engineer. I work across customer-problem validation, product definition, architecture, implementation, and early security and infrastructure decisions, 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.
I build with AI every day and think it is the best thing to happen to early-stage software in years. It makes a first version cheap to attempt, which is exactly why the expensive questions have moved. What to build, what to leave out, and what will quietly break under real usage are still judgment calls, and that is the work I do.
05 · New book
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 (including anything you built with AI), and the decision you need to make. If I am not the right person for the work, I will say so.
