Marc Ferré
Founder, Strategy & Build
Eight years at two Barcelona studios before starting EngineBuildFlow. Writes most of the back-end code and runs the kickoff calls.
The studio
A small studio is the point, not the limitation.
EngineBuildFlow has been a four-person operation since the first day, and it will stay that way. We turn down work we can't do well, we don't sub-contract design, and the person you meet in week one is the person who emails you in week six.
Marc started the studio in 2019 after eight years inside two larger Barcelona agencies. The pitch was simple: clients of a certain size — independent retailers, small manufacturers, single-owner consultancies — were being sold either a £600 template or a €60,000 enterprise build, and almost nothing in between. EngineBuildFlow was an attempt to fill that gap honestly.
Six years later, the studio runs from a small floor above a bakery on Carrer del Carme. We don\'t take retainers we can\'t honour. We\'re bilingual in Catalan and Castilian, work mostly in English with international clients, and prefer projects where the person paying the invoice is also in the kickoff call.
The work itself is split roughly half-and-half between marketing sites and internal tools. We particularly like the in-between projects — the inventory tracker that grew out of a Notion table, the booking system that started as a spreadsheet, the customer portal a founder hacked together one weekend that now needs to survive a real audit.
Who you actually work with
Four people. The same four, every time.
We don\'t use freelancers, contractors or white-label dev shops. Everyone you meet on the kickoff call is on the build.
Júlia Roig
Design Lead
Came from a small editorial design house in Girona. Responsible for type, tone and the studio's irritating insistence on real photography.
Pau Castellví
Front-end Engineer
Builds the templates, owns the performance budget, refuses to ship anything that doesn't pass Lighthouse cleanly.
Aina Domènech
Project Lead & QA
Keeps schedules realistic, hunts edge cases on real devices, and writes the documentation we hand off at launch.
Working principles
What we hold to, even when the schedule is tight.
None of these are taglines. They\'re the four things we say no to projects over.
Slow on purpose
Three projects in flight, never more. It's the only way the work stays this attentive.
Boring infrastructure
PHP, a single VPS, a backup script that has been running since 2020. We don't bring exotic tools to client work.
Real numbers
Every quote is itemised, and we send the same itemisation to the invoice. No "agency rounding".
Honest scope
If a project doesn't suit the studio, we say so in the first call and refer you on. We do this often.
