Founder Engineer & AI Architect
I build completeproducts. From the ideato the last deploy.
Creator of Rinari Agent and Rinari CLI. Web, mobile, AI agents and the servers they run on, designed, built and shipped by the same pair of hands.
I’m a software engineer from Costa Rica who likes owning the whole thing: the product idea, the interface, the API, the database, the deploy script and the film that launches it.
Most of what you’ll see below I built alone, end to end. The rest I led. Every number on this page comes from the repos themselves.
I built an AIengineer that provesits work.
Tell herwhat’s broken.
A real bug in a real project: the WELCOME10 coupon breaks the checkout.
She readsthe repo.
Files, tests and git state, before touching anything.
Reproducesthe bug.
A failing test first.
Fixes it.
Then runs the suite again.
Proves itwith tests.
Green because it passed, not because she said so.
DONE.Verified.
completion: DONE — all required kinds passed.

your request, from the CLISame session.
The engine owns execution, sessions, model routing, approvals and state. Each client is a window into it. Real captures, real sessions.
Desktop · Windows
Plan, Build and Review modes, approval gates, parallel subagents and an evidence panel for every claim.
Electron · React · TypeScript
GitHubTerminal · Engine
Ask, plan, fix and prove it from the command line, then hand the same session to the desktop.
Python · Typer · Rich · tree-sitter
GitHubBot · Web Studio
Moderation, tickets, levels, music and configurable AI, run from a web dashboard with Discord sign-in.
discord.js · Fastify · Next.js · BullMQ
rinari.bot
Different brands, different problems, the same standard. Live sites, captured as they are today.
01 / 08
Local business discovery · Costa Rica
A directory for Costa Rican businesses with an interactive map, catalogs, promotions, reviews, QR posters and paid plans.
Self-hosted AI moderation: safe content publishes, doubtful content goes to review, explicit content is blocked. Flagged uploads wait in a private quarantine with blurred previews.

Pickup football, played like a console game
Ranked player cards, broadcast-style lineup reveals, a live scoreboard, MVP votes, XP and teammate chemistry.
Three team generators (Balanced, Synergy, Draw) and one codebase shipped to the web, Android and iOS.
03 / 08
Game server platform · fan project
A Costa Rican WotLK fan server with its own web platform: accounts, an admin panel with two-factor login and a hall of champions.
A PayPal checkout delivered in-game by a custom C++ AzerothCore module: atomic, signed operations, replay- and rollback-tested.
04 / 08
Recipes, planner and pantry
Recipes, a weekly meal planner, a pantry with expiry dates, a community and shareable recipe cards with QR codes.
Portions that convert units and a shopping list built from the plan, with the Rinari AI assistant inside the kitchen.
05 / 08
Pet health, installable as an app
Profiles, medical records, vaccines, appointments, medications and routines for every pet, as an installable PWA.
A public emergency page for every pet, lost-pet mode and cron reminders for vaccines and appointments.
06 / 08
Travel agency · client work
The landing of a travel agency in San José, built to make people want to board.
A d3 globe that flies from SJO to ten destinations as you scroll, split-flap boards and a boarding pass that writes the inquiry.
07 / 08
My own hosting business
Small, honest hosting plans for Costa Rica, running on servers I administer myself.
Self-hosted panel behind a reverse proxy, provisioning scripts, and a site whose tests fail the build if it promises what the service doesn’t deliver.

Software & AI agency
The agency where I lead software development. Its site presents the team, the clients and the internal AI platform.
The logo draws itself along its real paths and six live demos are driven purely by scroll position.
What makes a product hold up is the part nobody sees. Three systems, drawn from their real architecture.
01Legado Tico
The web never touches the game database directly. Orders become signed, sealed operations that an outbound agent hands to a C++ module inside the game server. Bundles arrive in one mail, or not at all.
02DondeCR
Every text and image goes through a self-hosted TensorFlow.js service before it’s public. Three outcomes, and a quarantine where a reviewer sees a blurred preview until an audited reveal.
03Internal platform
For the agency I work with: identity, organizations and workspaces at the core, more than forty platform modules around it, and an AI operator that works through a model gateway with approvals and an audit trail.
Not a wish list: every one of these runs in something on this page.
Real products, real captures. Turn the sound on.
Landing pages and product sites that people remember: scroll-driven stories, WebGL, films and art, fast and bilingual.
Like this one, rinari.ai and Paulo Viajes
From the data model to the stores: dashboards, PWAs, payments, maps and native packaging with one codebase.
TeamMaker, DondeCR, MiMascotaCR
Assistants and agents that do real work: tool use, approvals, verification and evidence, not just a chat box.
Rinari Agent and Rinari CLI
Self-hosted or cloud: Docker, reverse proxies, backups with restore tests, deploy scripts and monitoring.
