Context

Developed as a freelance production platform for an agency-led brand campaign, the 'Original Forever' launch required a zero-latency reservation interface capable of enforcing strict store capacity limits across multiple retail locations in Argentina.

How I built it

Working from UI/UX design specifications delivered by the client, I engineered a lightweight Astro application utilizing modern JavaScript and modular SCSS for fast mobile rendering. Connected the front-end to a Supabase & PostgreSQL backend to lock time-slots in real time and deliver instant digital confirmations. Originally deployed in production at slotsadidasoriginals.com during the active campaign run.

Results

  • Real-time capacity synchronization across retail locations, preventing duplicate or over-allocated bookings during traffic surges.
  • Strict capacity enforcement and zero-latency slot selection across all locations.
  • Faithful pixel-perfect implementation from provided UI design specs.

Context

Developed as a freelance project for a brand experience campaign in Argentina, the 'Hotel Superstar' activation by Adidas & adiclub brought together music, art, and hospitality in a 1912 French-style mansion in Recoleta. The platform served as the central point for users to redeem club points and enter the exclusive hotel stay giveaway.

How I built it

Working from UI/UX design specifications delivered by the client, I engineered a fast, responsive web platform in Astro using modern JavaScript and modular SCSS. Connected the front-end to Supabase and PostgreSQL backend services to process 'Anotate acá' registrations and validate entry data in real time. Originally deployed in production at experienciasuperstar.com during the active campaign run.

Results

  • Real-time attendee registration ('Anotate acá') validated and synced directly to Supabase & PostgreSQL.
  • Sub-second mobile load times and smooth UX optimized for high campaign traffic.
  • Pixel-perfect execution faithful to the client's art direction and brand guidelines.
