What you can book me for
Three shapes. Countable outcomes.
Every engagement type has real shipped work behind it — not a case-study-less service page. Pick the closest shape, then we'll scope the specifics on a call.

Productized builds from $490
Fixed-price, fixed-timeline builds — live on your stack in days. Four tiers: $490 Live in a Day, $990 AI Pilot, $1,990 WhatsApp Bot, $6,500 Sprint. AI Pilots credit forward into the Sprint if you go bigger. Live or refunded.

Fractional CTO
Embedded technical leadership
One to two days a week for pre-Series A founders. Architecture, hiring calls, shipping velocity. You talk directly to me, not a project manager. Different scope from the AI Automation Retainer — this covers the whole technical function.

Start here
A sentence is enough.
Pick the shape closest to what you need and send one line about what you're building. I reply within 24 hours on weekdays — WhatsApp is usually faster.
If we're a fit, I'll come back with a honest take, a fixed price, and the next slot I can start. No deck, no funnel, no pitch.
FAQ
Before you ask.
- Where are you based?
- Ericeira, Portugal — 40 minutes north of Lisbon on the Atlantic coast. Most engagements are remote across Europe and the US. For local projects I'll meet over coffee or a surf.
- How quickly can we start?
- Usually within 1–2 weeks, depending on current load. I take on a handful of engagements at a time so availability varies — send a message and I'll tell you where I'm at, honestly.
- Do you work alone?
- I own strategy and architecture solo. For larger builds I bring in a small network of trusted collaborators (Solidity auditors, designers, PMs). You always talk directly to me — the person thinking about your product is the person building it.
- What's the fastest way to reach you?
- WhatsApp — typical reply within a few hours on weekdays (Europe/Lisbon), otherwise next business day.
