IT Consulting · Portugal

Software that fits your business, not the other way around.

J2B CODE is a small engineering team based in Portugal. We work with companies in Europe and North America on custom software, cloud infrastructure, and system integrations — the kind of work where details matter and off-the-shelf stops short.

What we do

Where we spend our time

Five areas of practice. Each one is something we do regularly, not occasionally.

Software Development

We build custom applications to spec — no framework overengineering, no off-the-shelf compromise. Clean code, tested, maintainable by whoever comes after us.

Web & Mobile Apps

Web apps and native mobile apps that work the way users actually work. We care about load time, accessibility, and what happens when the connection drops.

UI/UX Design

Interface design grounded in how people use software, not how it looks in a Figma prototype. We design for real screens and real workflows.

Cloud & Infrastructure

Architecture and migration on AWS, Azure, and GCP. We help teams move workloads without downtime and set up infrastructure they can operate without us.

Security & Compliance

Security assessments, dependency auditing, GDPR-aligned data handling, and threat modelling. We find the issues before they become incidents.

Who we are

"We started J2B in 2020 while working from a rented office in Covilhã, Portugal. Our first project was an internal reporting tool for a logistics company — nothing glamorous, but it ran without issues for three years. That's still the standard we hold ourselves to."

We're a small team. That's deliberate. Small teams make fewer handoffs, fewer assumptions, and fewer excuses. Every project has a named engineer responsible for it from brief to deployment.
