BRISA Coffee Shop

Brisa Coffee Shop is a premium, dine-in–first café website designed to feel calm, modern, and welcoming—while still being built for real business needs. The experience highlights the brand story and seasonal menu with an Apple-clean, editorial layout, then guides visitors into high-conversion actions like pickup ordering and table reservations. Key features include a categorized menu with dietary badges, a fast pickup flow with scheduling and notes, a reservation system with seating preferences and occasion details, a locations hub with hours and directions, and a lightweight cart drawer checkout. The UI uses pill controls, soft shadows, generous whitespace, and subtle motion for a polished, high-end feel.

VPSSCA Official

Official VPSSCA site built as a fast, multi-page static experience with HTML5/CSS3 and a Bootstrap grid for responsive layout. JavaScript and jQuery handle navigation behaviors, smooth scroll, UI interactions, and animation triggers, while WOW.js/ScrollIt power scroll-based reveals. The gallery is backed by Supabase Storage and Postgres, with Netlify Functions providing admin authentication, signed URL delivery, uploads, and metadata updates. Admin-only tooling supports sensitive content flags, captions, and secure session tokens, keeping public browsing clean while enabling internal content management. VPSSCA is the official and only certified ResMed vendor in Venezuela, authorized to distribute ResMed products and provide support and warranty service through approved channels.

NEXADEI

Official NEXADEI website and customer portal built in 2025 as a double-repository project: a TypeScript + Next.js 15 App Router frontend and a separate backend API repo. The frontend delivers the marketing site, bilingual en-US and es-CR experiences, SEO (metadata, JSON-LD, sitemap/robots), analytics tags, and a client/staff dashboard rendered as a client-side SPA with React Router, SWR data fetching, and Framer Motion transitions. A geo-aware middleware detects region from CDN headers and persists locale via cookies, while account flows cover sign-up, sign-in, password recovery, and referral onboarding. The backend (served at api.nexadei.com) provides session-based auth, staff bearer tokens, WebLaunch project management (projects, steps, cards, tickets, comments), media uploads, domain and SSL operations, and real-time notifications via Server-Sent Events. Supabase powers Postgres-backed content feeds with realtime updates for editorial posts. Deployment targets AWS Amplify for CI/CD and hosting, with AWS Certificate Manager integrated as an SSL provider option. I served as Project Lead, coordinating architecture, delivery, and cross-repo integration.
