Software engineer building practical AI tools

Paul Moreira

I build web apps, browser extensions, and experiments that turn new technology into tools people can actually use.

About

I care about useful software: tools that save a few minutes, make a decision clearer, or turn a rough idea into something people can try. AI has made building faster, but the real work is still judgment, taste, and understanding what should be simple.

Current focus

Now

Building

Small AI-assisted products, Chrome extensions, and focused web apps with clear everyday utility.

Exploring

Better workflows for prompting, verification, lightweight games, and interfaces that keep AI approachable.

Practicing

Shipping cleaner, faster, and with fewer moving parts so projects are easier to maintain over time.

Build Notes

Small AI Tools Are Where the Magic Is

The best AI products do not always need to be giant platforms. Sometimes the useful thing is a tiny tool that removes one repeated annoyance.

What Chrome Extensions Taught Me About Product Focus

Extensions force the idea to live inside someone else’s workflow, which is a good test of whether the product actually earns its space.
