I build the systems a business runs on. Brand, software, automation and AI agents for companies that still do too much by hand.

I started with the body. Then I built a business around it.

Venezuelan-born, Porto-based. I spent years in the mobility industry, and more than 20 in fitness and nutrition as an ISSA-certified personal trainer. That second part taught me to read every label.

The habit became Mindful Crumb, a protein brand with nothing artificial in it. Building it taught me everything else: brand, online stores, software, and the automation that lets a small team work like a big one.

Now I build the same for other companies. Leirós Consulting, CONCEPTi and GadgetGeeks Pro all run on work I designed, from the website to the payroll.

Let me show you what I've built.

Systems first, then brands · tap any card to open it

Have a project in mind? Let's talk.

I build agents that do the work and check with you first.

Each one has a single job, and each one asks a person before anything that matters.

CONCEPTi

Iris

Answers every new inquiry, keeps the team informed, and never decides alone.

GadgetGeeks Pro

Payroll Agent

Prepares payroll and the weekly schedule, then messages the owner. Money moves only after one tap.

Mindful Crumb

Mia

Talks to customers on WhatsApp, day and night, in the brand’s own voice.

Leirós Consulting

Doc Agent

Reads change requests by email, edits the real Word and PowerPoint files, and sends them back for approval.

My product

Zoe

Reads your wearable, your calendar and your food log, then sends one message every morning.

@Willy_Whiz on X

Brand Autopilot

Picks the day’s topic, drafts the post, emails it for approval and publishes at the best hour.

Tell me what you'd like to automate.

I'll build it so it runs on its own, and you get your time back to grow the business.

01Payroll & schedulesHours add up on their own, pay is ready on time, and everyone knows their shifts.
02New inquiriesEvery inquiry gets a reply right away, and you only talk to the people ready to buy.
03Your websiteA site that looks like the business you actually run, in English and Spanish.
04Double workYour tools pass information to each other, so nobody types the same thing twice.

The first system I built was my own body.

I'm an ISSA-certified personal trainer, and I study how the body works. It starts with what you feed it. Your gut is your second brain: what you eat changes how you think, how you sleep and how you perform.

Learn a few principles and food stops being a guessing game. You know what to eat, when to push, and when you can play. It's a matter of knowing your body.

Pillar oneWhat you feed your body.
