At Foco en obra, I built FocoAcredita almost single-handedly, creating its React and TypeScript frontend from scratch across 14 modules and developing its Node.js API for document validation and expiry tracking.
I also developed more than 20 modules for the main platform, including contractor accreditation, alerts and findings, labor control and forecasting, construction progress, and commercial management. I designed and built REST APIs with Node.js, Express, TypeScript, and SQL Server, with JWT authentication, Azure Blob Storage, and email and WhatsApp notifications.
At La Fórmula, I developed two client products that are now in production, handling their backend, frontend, and architecture. One was a real-time digital signage platform; the other was a management dashboard integrating Chipax and Buk.
At Talent360, I developed automated PDF report generation and built React and TypeScript views with search, filtering, server-side pagination, and Excel export. Earlier, at Teampers CRM, I rebuilt the frontend of a production PHP/Symfony application with responsive interfaces and reusable UI components.
