Freelancer profile translated to English.

Description

I design and develop complete digital products from Galicia: high-performance websites, web applications, and SaaS platforms.

My background in multimedia design (UDIT, Laus de Oro 2015) and over 10 years of experience as a developer allow me to work throughout the entire project lifecycle: from visual design and user experience to technical architecture and production deployment.

Depending on the project's needs, I work with two approaches:

→ Content websites and landing pages: Astro or Next.js, focusing on performance, Core Web Vitals, technical SEO, and conversion. Fast, accessible, and optimized sites.

→ Web applications and SaaS: Next.js (App Router, Server Components), TypeScript, Supabase, and PostgreSQL. Integrations with Stripe (payments), OpenAI/GPT-4 (artificial intelligence), Clerk (authentication), Algolia (real-time search), and Vercel (deployment and analytics).

In all projects, I design reusable component systems, ensure accessibility (WCAG AA+), and plan with detailed documentation and clear deliverables.

Main Stack: Next.js · Astro · React · TypeScript · Tailwind CSS · Supabase · PostgreSQL · Stripe · OpenAI API · Clerk · Algolia · Vercel · Playwright · Vitest

Languages: Spanish (native), Galician, Portuguese, Professional English.
