Full-stack developer specializing in React, Node.js & modern web systems. I turn complex requirements into fast, scalable products — fluent in 4 languages, ready to work with any team, anywhere.
I'm TORTOKILLER — a full-stack developer who cares about shipping products that matter. My background spans frontend polish and backend architecture, meaning I can own a feature end-to-end without losing sight of the user experience.
I work with modern JavaScript ecosystems (React, Vue, Node.js) and have strong database experience across both SQL and NoSQL. I approach every project with a product mindset: understanding business goals, not just technical specs.
What sets me apart: I'm multilingual and multicultural, which means I thrive in international teams, communicate clearly with diverse stakeholders, and build products for global audiences.
A curated set of tools I use daily to build real products. No fluff — just the technologies I'm confident deploying in production.

Real-time business intelligence dashboard with D3.js charts, WebSocket data streaming, and multi-tenant architecture for B2B clients.
Custom content management system with i18n for 4 languages, SEO automation, and a visual page builder. Deployed for a cultural organization in Barcelona.
