Two engineers. One obsessive standard.
JSquared — “J squared” — is João Bastos and João Santos, a bespoke software studio in Portugal. We build tailored web apps for businesses that want a real product, not a template.
Claude-native, engineer-led
We pair senior engineering judgement with AI that does the heavy lifting — so a two-person studio ships at the pace and polish you'd expect from a much larger team. The AI is how we deliver fast and consistently; the engineering discipline (testing, security, GDPR, clear contracts) is what makes it safe to rely on.
Why “squared”
There are two of us — and we're both called João. João + João = João², “J squared”, J². It's also a promise: to make your business look and feel like more than it is today — amplified, not just added to.
What we believe
Craft over volume
We take on a few projects at a time and finish them properly.
You own it
Code, data and IP transfer to you on final payment. No lock-in.
Privacy by default
EU-hosted, GDPR-minded, secure — especially for products used by families and children.
Plain dealing
Clear scope, clear price, clear timelines. We say what we'll do and what it costs.
