Senior Frontend-Led Full-Stack Engineer

I provide React product engineering for the web platform of a listed multinational operating across multiple regions and languages. The platform uses a multi-team micro-frontend architecture.

I own a shared React component library used by multiple product teams. I also scaffolded a schema-driven templating monorepo with shared service contracts, server/browser rendering builds, versioned releases, and CSS isolation that eliminated cross-team style leakage in a Module Federation setup.

I delivered full-stack functionality for a social-casino platform across Next.js and Express services, PostgreSQL schemas, React administration tools, and animated game interfaces. I owned features across frontend, backend, validation, and operational workflows.

I built a gamification system, a real-time roulette mini-game, jackpot image sharing with dynamic TTL caching, free-spin flows, and a bulk XLSX/CSV upload pipeline with layered client and server validation.

I worked as senior frontend engineer on a fantasy-sports and watch-along platform serving the Brazilian market. I designed a custom routing layer on top of Next.js for history management, scroll restoration, and modal navigation.

I built two competitive game modes end to end, including entry flows, real-time play, leaderboards, and results. Brazilian Portuguese localization was delivered alongside all features.

I was the primary frontend engineer on a two-person team building a multi-tenant SaaS product for US municipal fire departments and building-inspection offices. I owned the frontend end to end and integrated closely with a Django REST backend.

I led migrations from JavaScript and Create React App to TypeScript and Vite, standardized forms and data fetching, and delivered ArcGIS workflows, tenant configuration, a 2FA flow, administrative surfaces, and an AI-assisted issue-description workflow.

I worked on the public marketing web-platform team and its design-system component libraries powering mongodb.com. This was a parallel client engagement.

I led the frontend portion of a company-wide marketing automation migration from Pardot to Eloqua, reimplemented site forms without production incidents, delivered a coordinated multi-repository announcement-bar feature, and improved Hero component Core Web Vitals and LCP.

I worked on a B2B2C school-photography SaaS product. I owned the administrative photo-cropping experience during an active CakePHP-to-Next.js migration.

I handled image rotation, coordinate-space edge cases, crop-data persistence, and iterative stabilization against real customer data.

I developed frontend capabilities for a managed-Kubernetes and OpenStack SaaS product used by enterprise infrastructure teams. My work covered the administrative product surface and reusable UI foundations.

I built design-system primitives, defined the Redux caching and persistence strategy adopted across teams, established Storybook and Jest infrastructure, and migrated build tooling from Webpack to Vite.

I delivered frontend functionality for a commodity-trading management system with real-time data and automatically updating interfaces.

I designed and shipped real-time React and RxJS components against live trading data, and established Storybook as the team's component development environment.

I tech-led the redesign and rebuild of a hotel-management CMS used by more than 2,000 hotels across the group. I worked full stack across Angular, Backbone, Node.js, Express, PHP, and databases.

I designed architecture and base components, recruited and mentored a small engineering team, built booking-engine integrations with Booking.com, TripAdvisor, and Trivago, and authored a safe multi-hotel SQL query utility.

I started my web-development career at IGM Web, part of the Hotusa group, and Estudi Jmes1. I worked with PHP, jQuery, and MySQL.

This work established the foundations for later hotel-CMS development and my full-stack engineering career.

High Technical Certificate in Computer Engineering completed in Girona, Spain.
