Why a studio in Barcelona
We work from Barcelona. The person who scopes and quotes the project is the person who builds it and is accountable for it running. No intermediaries, no hand-offs. Next.js, TypeScript, AWS, one hosting setup, one monitoring config. Nothing exotic, everything maintained. The same stack used for TitanOS (the frontend on the Linux system on Philips' 2026 TVs, 18 million users in Europe) and for an AI assistant at Opella / Sanofi (11,000 employees).

Frequently asked questions
Do you only work in Barcelona?
No. Wallion is based in Barcelona, but we build for SMEs across Spain. What matters is that the person who scopes the project is the person accountable for it running — no hand-offs, no ghost teams.
How long does it take?
4–8 weeks from fixed quote to live. You see progress every week — working software, not status decks.
Is the Diagnosis credited?
Yes. If you proceed with the build, the Diagnosis cost (€1,900) is credited against the build quote.
Custom software or SaaS?
Depends on your case. If off-the-shelf SaaS does 90% of what you need, buy it. If you're doing 40% manually because the tool doesn't fit, custom software is cheaper. <link>More on when it's worth it</link>.
Is Wallion the same as Wallion Mobility or Wialon?
No. Wallion is the trading name of FINE PROGRAMS SL, a custom software studio in Barcelona. Not Wallion Mobility (electric mobility). Not Wialon (fleet GPS software).
