Why Regi exists
Regi is my way to bring engineering discipline to everyday check-ins for hospitality teams that care about compliance, performance and trust.
Automation with accountability
Every workflow is observable, versioned and documented. If something breaks, we know before the authorities do.
Craftsmanship over shortcuts
From custom field versioning to detailed runbooks, I write systems other engineers can maintain.
Care for the people behind every booking
Whether it's a front desk team or a solo host, I design flows that remove stress instead of adding steps.

What I bring to hospitality teams
Backend-first thinking
Node.js, TypeScript, Go + Fiber, PostgreSQL and AWS are my daily toolkit to keep reports flowing.
Reliability playbooks
I design idempotent processes, alerting and recovery steps so you sleep even when authorities change forms.
Clear, bilingual communication
I document, mentor and publish in English and Spanish because compliance is easier when everyone understands it.
Side projects that keep me curious
n4xo.com
My personal site built with Astro, Svelte and Tailwind to share talks, blog posts and experiments.
SolidURLs
A URL shortener powered by NestJS, TypeScript and PostgreSQL focused on observability.
API Wars
My senior thesis comparing REST, GraphQL and gRPC by building the same social network backend in Go.
Lightweight newsletter service
Go-based subscription service with automated campaigns and zero-friction onboarding.
Let's build frictionless check-ins together
