Custom Web Development Spain Built for Performance & Growth
Stop losing Spanish buyers to slow templates and RGPD/AEPD privacy risks. Tech Nova Byte provides full-stack web development built specifically for companies operating in Spain—combining sub-second page speed, automated 21% IVA tax logic, Bizum & Redsys payment integration, and UNE-EN 301 549 (WCAG 2.1 AA) accessibility compliance in one seamless package.
Why Generic Templates Fail Spanish Businesses
Standard web templates are packed with bloated code that slows down your site and leaves you vulnerable to expensive AEPD fines under RGPD and LOPDGDD. Here is the difference between a template and custom web development built for the Spanish market.

How We Secure Your Spanish Digital Operations
Building for a Spanish audience requires non-negotiable legal, financial, and technical safeguards. Here is how we bake them into your custom web development project.
UNE-EN 301 549 & WCAG 2.1 AA
We code screen-reader compatibility and color-contrast benchmarks directly into your frontend, protecting your company under Spanish and EU web accessibility regulations.
Automated 21% IVA & Invoicing
Spanish tax rules are specific. We integrate automated tax calculation engines directly into checkout for 21% IVA and compliant invoicing workflows.
RGPD & LOPDGDD Privacy Protection
We architect cookie consent banners, user consent logs, and data processing protocols specifically to satisfy AEPD mandates and European data privacy laws.
Bizum & Redsys TPV Integration
We integrate Spain's most trusted payment methods—Bizum, Redsys TPV Virtual, SEPA Direct Debit, and Stripe EU—to eliminate checkout friction.
AWS Spain Cloud Infrastructure
We host client applications on local AWS Spain nodes (eu-south-2 in Aragón) to keep data in Spain and deliver sub-second data response times.
Bilingual / Multilingual Ready
We build multi-language architectures capable of dynamic language switching between Spanish (Castilian), Catalan, Basque, Galician, and English.

Trusted by Growing Companies in Spain
Direct feedback from executives who trust Tech Nova Byte for their core web development.
