Selected projects

Built, shipped, and honest about status.

01

Live in production

Hotel Point — Property Management SaaS

The full operational stack of a hotel, in one system.

Hotel Point is a multi-property PMS covering reservations, front desk, housekeeping, OTA channel sync with Booking.com and Expedia, and finance. As a full-stack developer on the product, I'm refactoring the booking-engine backend for scalability and integrating payment processing across five gateways — Stripe, Viva Wallet, Nexi, Cardlink, and Piraeus ePay. It's Laravel at production scale: multi-tenant, queue-driven, and monitored.

  • PHP · Laravel
  • MySQL · Redis
  • Stripe + 4 gateways
  • Docker · CI/CD

Client project — launching soon

Mathias Gourmet — Restaurant · Bogotá

A bilingual brand site engineered for local search.

Spanish-first marketing site for a Bogotá burger restaurant — locale-routed pages, a structured menu with real COP pricing, and WhatsApp ordering. Under the hood: one typed content dictionary drives every word in both languages, a hand-built Schema.org graph goes down to per-item menu offers, and a dependency-free binary parser reads image dimensions straight from JPEG, PNG, and WebP file headers.

  • TypeScript
  • Tailwind CSS
  • JSON-LD · i18n

03

Client project — launching soon

Nails by Valentina — Salon · Bogotá

Front-end craft, technical SEO, zero dependencies.

A bilingual site for an independent nail artist: statically prerendered Spanish and English routes, i18n hand-rolled with no libraries, and full local-SEO machinery — LocalBusiness structured data, auto-generated sitemaps, and per-locale social cards rendered at build time. Scroll animations honor reduced motion and the whole site stays readable with JavaScript turned off.

Built & tested — pre-audit

Packsy.fun — Web3 Protocol

Verifiable pack-opening, on two chains.

A launchpad protocol for collectible card-pack games: creators deploy a themed pack economy in minutes, and players open packs with oracle-free commit-reveal randomness, receiving their pulls as on-chain tokens. I wrote both implementations — roughly 1,900 lines of Anchor/Rust for Solana, mirrored by Foundry/Solidity contracts with invariant fuzz tests — plus a NestJS keeper service that makes opening a pack a single wallet signature, all verified end-to-end on a local validator.

  • Solidity · Foundry
  • NestJS
