AI-powered development · Lisbon

From briefing
to working product
in weeks.

I'm a freelance developer based in Lisbon, with over 20 years of technical experience. When you contact me, you talk directly to the person building your product.

There's a misconception: most people believe that quality and speed are incompatible. They're not.

"No timesheets, no middlemen. Just the product on your domain by the date we agreed."

— António, founder
◇ Services

Three things, done properly.

I work within these three. If your project doesn't fit, I'll be honest about it and point you somewhere that does.

01Marketing & content

Website from scratch

Every website is built from the ground up for your business. Design that represents who you are, performance that delivers, and SEO that actually works. No templates with your name pasted on.

  • Next.js · Astro
  • CMS of your choice
  • 1–3 weeks
02Internal tools & SaaS

Bespoke applications

For when a website isn't enough. Reservations, client portals, integrations: if you have a concrete problem, I build the right solution for that problem. Talk to me first and I'll be honest about what makes sense.

  • React · TypeScript
  • Postgres · Supabase
  • 3–8 weeks
03Methodology

AI in the process, not the pitch

I use artificial intelligence to deliver in weeks what other teams take months to build. It's not a sales argument — it's literally how I work. The result is yours, regardless of the tools I used.

  • Claude · Codex
  • Tested, reviewed
  • Always shipped by me
◇ Process

A four-week loop,
repeated until it's right.

  1. Week 1Briefing and architecture

    We start with a meeting and leave with a document.

    Before any code, we align on objectives, users, technology and timeline. No surprises mid-project.

    • +60-min kick-off call
    • +Written brief & fixed quote
    • +Calendar slot reserved
  2. Weeks 2–3Accelerated build

    Faster, without cutting corners.

    I use assisted development tools to build faster, without sacrificing code review, testing or engineering best practices. The time saved goes into code review, not shortcuts.

    • +Daily preview deploys
    • +Async Loom updates
    • +Live board with every task
  3. Week 4Review and delivery

    I don't ship and disappear.

    The last week is for reviewing with you, refining details and documenting everything. The product is yours and you get everything you need to manage it on your own.

    • +Handover doc + Loom
    • +2 weeks of free fixes
    • +Optional retainer
◇ About

One person.
One inbox.
One Slack channel.

I work alone, with AI as a central part of the process. There are no account managers or layers between the briefing and the code. What you tell me in a meeting goes directly into the product, built by the same person you were talking to.

I have over 20 years of technical experience: from senior Java developer to manager of critical infrastructure at large Portuguese companies. Along the way, I launched and ran my own internet projects. Today I apply that background to one thing: building digital products that work, for businesses that don't have time to waste.
