Product engineering

Web Application Development

A fast, production-grade web application your customers or staff actually keep using — built to last longer than eighteen months.

What's included

01
UX and technical architecture planning
02
A frontend and backend built for your actual load
03
Third-party integrations
Payments, auth, and the APIs you already depend on.
04
Automated testing on every release
05
A staging environment before production
06
Launch support and a short post-launch fix window

Who it's for

Founders building a customer-facing product

A dashboard, portal or marketplace your users will actually log into.

Ops teams that need an internal tool

Something faster and more durable than a spreadsheet or a plugin-stacked CMS.

Teams selling online

An e-commerce build that needs to handle real payments and real traffic, not a template.

How we work on this

We treat performance and testing as part of the build, not a cleanup pass at the end. Architecture decisions — how the app scales, how it integrates with payments or auth — are made explicit in the estimate, not discovered halfway through.

Built with

Every release goes through code review and a staging environment before it reaches production.

What we commit to

You own the code and the IP.

Everything we build transfers to you on completion and payment — no licensing traps, no dependency on us to keep running your own product.

Senior engineers only.

Every person on your engagement is senior. Nobody junior is billed at a senior rate, and nobody senior pitches the work only to hand it to a team you never meet.

EU-based, GDPR-native.

We operate under Portuguese and EU law, in your timezone, with data handling that's GDPR-compliant by construction, not by afterthought.

A written estimate before we start.

You get a written, fixed-scope estimate before any work begins — not a verbal ballpark, not a moving target.

Representative engagement — anonymised

Subscription management portal for a media business

Subscribers manage their own accounts without emailing support, and the support team spends its time on the tickets that actually need a person.

Common questions

Do you build e-commerce platforms too?

Yes — e-commerce sits inside Web Application Development rather than as a separate service, because a storefront is a web application with payments and inventory attached, not a different discipline. Scope and price it the same way: a written estimate against your actual catalogue and checkout requirements.

Will the application handle growth in users or traffic?

That's an architecture decision we make explicit at the estimate stage, not something we hope holds up later. We build for the load you're actually expecting, with a clear path to scale further if the product takes off — not over-engineered for traffic that may never arrive.

Do you provide staging environments before launch?

Yes, on every build. Nothing goes to production without going through a staging environment first, and you can look at the staging link at any point during the engagement, not just at the end.

What security practices do you follow during development?

Dependencies are kept current, access follows least-privilege by default, and code goes through review before it merges. For anything handling sensitive data, we agree specific security requirements with you at the scoping stage rather than assuming a default.

Dashboard, portal, marketplace or storefront — send the details and we'll scope it properly.

Essential

Required for the site to work — stores your cookie choice only (cbl_consent). Can't be switched off, and doesn't track you.

Analytics

Google Analytics 4 (GA4) — helps us understand how the site is used, in aggregate. Doesn't load until you switch this on.
