Garín, Buenos Aires · Argentina

Senior full-stack engineer with end-to-end product ownership: system design, data architecture, frontend, native mobile apps, hardware integration and production deploys.

I built Huésped+, Argentina's first agentic hotel —the guest PWA with digital check-in, in-app payments and an LLM concierge that answers about the hotel and about each stay.

Unusual breadth —React/Next.js, React Native/Expo, Rust/Tauri, Node/Bun backends— with a strong focus on AI-assisted engineering: custom MCP servers, agents and LLMs in production with guardrails.

Huésped+ in production with real hotels, and GymAdmin —my SaaS for gyms in Latin America— end to end.

Projects

• Huésped+ — Argentina's first agentic hotel: the guest PWA, customized for each hotel.
  • Each hotel ships it on its own domain, with its own brand and content: the same product looks different in every property, with no deploy per client.
  • Guests check in and out from their phone, order room service, pay in-app and fill in the post-stay survey, without installing anything.
  • The AI concierge answers 24/7 about the hotel —services, hours, policies, local tourism— and about each specific stay. Multilingual, with anti-hallucination guardrails and hand-off to the front desk when it doesn't know.
  • Live in real hotels across Argentina.

  Next.js, Fastify, Prisma, PostgreSQL, LLM

• Gym Admin — Multi-tenant SaaS for gym management: members, memberships, cash register and workout plans.
  • Each gym gets its own domain and sees only its own data: one deploy, many clients.
  • Covers the front desk's day to day: member sign-ups, payments, expiring memberships, cash register and workout plans.
  • It's the backbone the mobile app and the fingerprint access control build on.

  Next.js, Hono, Prisma

• Gym Mobile App — The system's white-label app: check-in, sales and debts from the gym's front desk.
  • White-label app: each gym ships it with its own brand and icon.
  • Handles DNI check-in, pass sales and debt collection on the spot, no PC needed.
  • Shares the API contracts with the backend, so a schema change breaks the build instead of breaking production.

  Expo, React Native, TanStack Query

• Fingerprint Reader — Fingerprint access control with ZKTeco readers, integrated with gym-admin in real time.
  • A native Rust + Tauri service that talks directly to the ZKTeco readers on the local network.
  • It pushes every punch to gym-admin over WebSocket, so the front desk sees it instantly.
  • If the network drops, it queues events on disk and retries when it's back.

  Tauri, Rust, React

• Goblin — A native streaming app with MPV, Stremio addons, torrents and debrid services.
  • A desktop app built with Tauri + Rust for streaming content.
  • Works with Stremio addons, torrents and debrid services.
  • Playback is handled by an embedded MPV: it plays any codec without fighting browser limitations.

  Tauri, Rust, Svelte, MPV

• Slop Together — A Jackbox-style collaborative dubbing game: one host plus phones via code, nothing to install.
  • The host starts the game on a computer and everyone joins from their phone with a code, nothing to install.
  • Each round hands out a video and everyone voices it; then everyone votes for the best dub.
  • All live sync runs over WebSockets.

  Bun, React, Tailwind

  https://slop.pepo.ar/
• Mecánica Torres — A real client's landing page: mobile mechanics in Pilar, built around WhatsApp.
  • A site for a mobile mechanic in Pilar: the business goal is to get WhatsApp messages.
  • Every section pushes toward that action —services, coverage area and warranty are written to answer questions before they're asked.
  • In production and generating real leads.

  React, Vite, Tailwind

• Price Scrapers — Price tracking with scrapers for Día/VTEX and Mercado Libre, no headless browser.
  • The scrapers hit the internal Día/VTEX and Mercado Libre APIs directly, no headless browser involved.
  • It keeps price history in SQLite to see how each price moves over time.
  • A React front shows the products you follow and alerts you when they move.

  Bun, Hono, SQLite, React

• Bonitas Ayelen — Online booking for a beauty salon in Garín: services, staff and deposits.
  • Bookings are 100% online: the client picks the service, adds several to the same slot, and chooses staff, day and time.
  • It charges the deposit at booking time and sends the confirmation instantly.
  • It also handles equipment rental with requirements and supply combos for professionals.
