I build products
that actually ship.
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.
Engineer first.
Product thinker always.
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.
- Clean, maintainable code over clever hacks
- Performance-first frontend — every millisecond matters
- Strong documentation and communication habits
- Ownership mentality — I ship, I don't just code
My tech stack
A curated set of tools I use daily to build real products. No fluff — just the technologies I'm confident deploying in production.
Projects
Custom-built website for an independent symphony orchestra in Barcelona: concert calendar, conductor & musician profiles, season programming, and a musician recruitment page.
Booking platform for a Barcelona barbershop & makeup studio: live appointment calendar with service/date/time selection, automatic WhatsApp confirmation, and transparent fixed pricing.
An interactive "performance" pushing pure CSS to its limits: a hover-driven turntable, a :has()-powered cassette player, clip-path stage lighting, and container-query sheet music — almost no JavaScript involved.
A 16-step drum sequencer that builds its own UI, schedules its own audio, and draws its own visualizer — entirely in vanilla JavaScript, no frameworks or build step.
