Product Designer & Product Management

Creativity to solve real problems

I'm Pedro. Senior product designer and product manager. I take products end to end, then into the strategy and business calls that actually ship them. Design systems, 0-to-1, and AI built into how I work since 2024.

Why Me

Ownership

Leading product decisions backed by real numbers.

Led and mentored a team of 10 designers across multiple enterprise accounts, cutting discovery time by 60% for a major client engagement.

Cut half of an MVP's scope as Sphere of Six's first product hire, using direct user validation to bring development cost down 30 to 40%.

Compressed a 10-week design cycle to 4 weeks by rebuilding discovery and prototyping around AI tools, protecting runway for a pre-revenue startup.

Localized a payment experience for Brazilian users, cutting billing support tickets by 38% and growing site usage by 24%.

How I work

Same job, different domains, same three moves.

Nine years across B2B and B2C taught me a process is only as good as what it cuts, not what it adds.

01

Start with the constraint

Before I open a design tool, I want the one constraint that will actually break the build: time, trust, or technical debt. That's what shapes the design, not the other way around.

02

Prototype at real fidelity, fast

I've used AI since 2024 to go from a rough idea straight to a clickable, realistic prototype. Skipping static wireframes means trade-offs show up while they're still cheap to fix.

03

Name the trade-off out loud

Every scope cut has a cost. I'd rather say what we're giving up upfront than let someone find out the hard way later.

Got something worth cutting scope for?

I'm open to senior product design and PM-track roles, and to conversations before there's a job description.
