Hello, I'm
Adrian Rojas Barrera — Freelance Web Developer in Barcelona
Senior freelance web developer in Barcelona, full-stack. I build Ruby on Rails SaaS, PrestaShop e-commerce stores, and WordPress sites that actually convert. 10+ years shipping, working worldwide.
Services
One mindset across every engagement: ship working software.
Custom web development
Has your website become slow, insecure or limited? I build websites without templates or plugins: they load in under a second, withstand attacks and grow with your business. Coming from WordPress? I migrate your site without losing rankings.
- Loads in under 1 second
- No plugins to break
- Hardened security built in
- SEO-safe migrations
Ruby on Rails
SaaS MVPs in 6–10 weeks. PostgreSQL, Stripe, Hotwire. Senior-level Rails work for founders and SMEs.
SaaS MVP development
Fixed-price MVPs. Auth, billing, admin, multi-tenant — the boring 70% done right.
PrestaShop
Custom modules, full stores, and rescues from WooCommerce or Shopify. Six-figure store experience.
WordPress
Custom corporate sites, fast performance, and SEO-safe migrations. WooCommerce ready.
Specialized in your industry
Web solutions built around the way your business actually sells.
Online store development
E-commerce that actually sells: catalog, payments, logistics and SEO from day one.
Web design for law firms
Authority-building sites that turn legal queries into consultations.
Web design for artists and personal brands
Your site as the hub of your brand: portfolio, tour dates and ticket sales.
