Hebert Porto
I build apps for iPhone,Android,the web,the desktop,the terminal,
from first sketch to launch.
I’ve shipped native and cross-platform software for twenty years. Today AI agents write much of the code, and I review every change before it goes out.

Each project, on the device it runs on.
Six I’m proud of. Open one to see the problem, what I decided and how it turned out.
SupraFitPro
A coaching platform for independent personal trainers in Brazil. Coaches work in a web portal built around the Radar, which shows who trained, who went quiet and who is ready for more load. Their clients log every set in a free phone app.
Kiddo Wallet
An allowance app that teaches kids what money is. I designed, built and released it on both stores, then moved the whole backend to Supabase while families kept using it.
Wizarding Bruno
The companion app for Bruno Santiago’s wizarding fan community. Fans join one of four houses, earn points for their house, and since v3.0 duel each other in a card game. Built with Bruno, released on both stores.
Mind Life Puzzle
Fifty-two weekly scripture word searches, matched to the 2026 Come, Follow Me schedule. I wrote it twice, once per platform, so dragging and haptics feel native on each phone.
Thyara Porto Interiors
A site for a design consultant: a gallery of her projects, a page for the design firms she works with, and a blog she publishes without a developer.
My agent toolkit
The house rules my agents follow: skills, subagents and hooks for architecture, features, tests and releases. With it I can run several agents at once and still review every change myself.
Everything else.
Recent projects that are still live. Twenty years of earlier work isn’t listed.
Small pieces, worked on until they felt right.
A spring I tuned, a gesture, a tool I wrote for my agents. Each one runs here in the page and links to its source.
Open the bench
Twenty years in, still shipping.
I wrote my first production code on technology nobody uses anymore. Since then the ground has moved four times: from the desktop to the web, from the web to phones, from native to cross-platform, and now to code written alongside AI agents. Each time, I learned the new ground by shipping on it. That’s the useful part of twenty years: I’ve seen what lasts and what doesn’t, and I build for the part that lasts.
Along the way the work has taken me to very different places. I’ve built for healthcare in more than one setting, and I’ve built several apps on top of maps, with live location, tracking and people talking to each other in real time. I’ve worked on AI products that create a custom image or soundtrack for each person, on reading apps where the page has to feel right, on interfaces where animation carries the experience, and on a sports betting app, where every second on screen counts. So when a new project lands, there’s a good chance I’ve already met its hardest problem somewhere else.
I also build apps of my own, and today they live under Porto Stack, my studio, from a kids’ allowance app to a fan community where houses duel with cards. AI agents write much of the code now, held to my standards by skills I wrote myself, and every change still goes past me before it ships. A few times a year, I take on an outside project through the studio.
