Tech Lead by day, freelance by life

I'm Adrian Rojas Barrera, a senior freelance web developer with an office in Sabadell (Torre Millenium building, Avinguda de Francesc Macià 60), Barcelona metro area, Spain. I've been building production web software for over 10 years.

Currently I'm Tech Lead at Cendyn (a hospitality SaaS multinational) by day, and a freelance developer the rest of the time. This means I'm not "between contracts" — I'm choosing to take on a small number of freelance projects per year for clients whose work I find interesting.

What I work on

  • Ruby on Rails SaaS — my specialty. Multi-tenant apps, Stripe billing, PostgreSQL.
  • PrestaShop — custom modules, full stores, migrations. I built Tapacontador.com (six-figure revenue store).
  • WordPress — bespoke corporate sites, WooCommerce, ongoing maintenance.

How I work with clients

  • Free 30-minute discovery call.
  • Written, fixed-price quote within 24 hours.
  • Weekly demos. Code in your repo from day one.
  • Handoff with documentation and recorded walkthroughs.
  • Optional retainer afterwards. Never required.

Languages

Spanish (native), Catalan (native), English (professional). All client communication can happen in any of the three.

Education

BSc Computer Engineering, Universitat Pompeu Fabra (UPF), Barcelona.
