Freelancer profile translated to English.
Back to original languageAbout Alex
I am Alex Fan, a full-stack developer specializing in creating custom websites with Next.js for international businesses in Spain. I don't work with templates: each project is designed and programmed from scratch, adapted to the real needs of the business.
My differential value: I am bilingual Chinese-Spanish, which allows me to create authentic multilingual websites, not simple automatic translations. I work with restaurants, shops, travel agencies, and B2B companies that need to reach both the local and international markets.
What I do: corporate websites, B2B/B2C e-commerce, online booking systems, ERP panels, and multilingual/multi-currency solutions.
Stack: Next.js, React, TypeScript, Tailwind CSS, Node.js, PostgreSQL, Stripe.
Based in Barcelona. Available for projects throughout Spain and Europe.
