Javier Goldschmidt

The central digital hub for a biotech startup incubator. We needed a platform that could serve complex scientific data to global investors while remaining easy for non-technical staff to update.

• Architected a scalable Internationalization (i18n) system serving content in English, Spanish, and Portuguese with low latency
• WordPress-controlled frontend & form builder where admins can route submissions to specific Airtable bases or Emails based on logic
• Implemented high-performance video optimization for AI-generated assets, ensuring fast Time-to-Interactive (TTI)
• Built a dynamic portfolio system managing data for 90+ startups with real-time filtering

A bespoke membership ecosystem serving 1,500+ monthly subscribers. Unlike standard SaaS tools, this platform was engineered to handle the specific economic volatility of the region while keeping users engaged through gamification.

• Engineered a unique 'Inflation Adjustment Engine': An opt-in Cron system that fetches Consumer Price Index (IPC) data via API and automatically updates subscription values quarterly
• Developed a unified Payment Orchestration Layer triggering transactions via MercadoPago, PayPal, and CBU (Bank Debit) APIs
• Built a WebGL '3D Avatar Creator' (Three.js) allowing users to design, download, and share branded digital assets
• Managed the migration and stability of 1,500+ active recurring subscribers

Architected the complete migration of El Gato y La Caja from a monolithic WordPress VPS to a decoupled Headless architecture. The goal was to maintain the editorial flexibility of WordPress while achieving the performance and security of a static frontend.

• Migrated 6 years of content to Next.js (App Router) with Incremental Static Regeneration (ISR)
• Developed 'Smart Revalidation': A custom WP plugin that triggers precise cache purges, reducing processing costs
• Developed custom Gutenberg blocks that render identical React components in both the Admin and Frontend
• Reduced hosting costs by offloading media to S3 Buckets via custom-made plugin

A backend service built to patch the limitations of Tiendanube e-commerce platform. It acts as a bridge between the storefront, the warehouse, and the user.

• Engineered 'Virtual Bundling' logic to sync stock across compound products in real-time
• Built a programmatic Gift Card system that generates unique codes and renders printable high-res PNGs on the fly
• Extended products with 'Pre-sale' functionality to allow users to purchase products before they are available
• Extended the Tiendanube Admin Panel UI using Nexo SDK for seamless staff operations
• Automated the delivery of digital goods
• Built a micro-frontend that embeds real-time Tiendanube products directly inside editorial content to convert free readers into buyers without interrupting their reading experience.
• Made a permission-based Dashboard using Looker Studio so staff and authors could visualize sales data and inventory levels

Lead engineer for multiple data journalism projects. Specialized in transforming dense datasets (gender gaps, poverty metrics, disability rights) into emotional, accessible web experiences.

• Futuro Programado: Visualize the gender gap in tech with custom SVG animations
• Parece Elemental: Optimización de scrollytelling con medios pesados para dispositivos de gama baja en áreas con conectividad limitada
• CLACAI: Built a WCAG 2.1 AA compliant platform specifically for screen readers and keyboard navigation
• Eureka 3D Reading Experience: A physics-based interactive book for children running in the browser

A high-octane 3D runner built in Unity. I was solely responsible for the engineering of core physics, gameplay loops, and UI systems.

• Shipped a commercial title, managing the full release lifecycle
• Engineered a custom physics-based character controller
• Implemented aggressive object pooling for performance
• 3000+ downloads and overwhelmingly positive feedback on Steam
