Engineering Projects
Tools, platforms, and experiments. Private projects require access — reach out via LinkedIn.
Family trips end up scattered across phones and group chats. Mapa gathers each one into a shared map of places and photos that you can replay as a route and print as a book or a poster. The whole API runs as a single Lambda function, and photos stay private, opened only through signed links. By invitation.
Habit apps only work when you remember to open them. OnFire puts your streak on the face of your Garmin watch, so every time you check the hour you see whether today is on track. The watch face reads today's state straight from one small serverless endpoint.
How do you run a portfolio of software projects when most of the work is done by AI agents? Every request, defect and decision becomes a numbered item in one queue, and each agent works in a fixed role (product owner, developer, designer) and hands off through files the others read. The agents propose and deliver; a person approves, and nothing costly or irreversible runs without a written authorization.
To-do lists grow until nobody reads them. DayPlan gives you one place to capture anything and lets you choose at most five things for today; older items come back to be decided instead of piling up. The list lives in the phone's own storage, and the cloud only syncs it and sends the reminders.
Before a meeting it is hard to remember what you know about each person in the room. Dory matches your calendar with your notes and shows, for each attendee, who they are and what you meant to talk about. Your notes stay as you wrote them; AI only condenses them into a short summary per person.
Taking notes during a call or a conversation pulls you out of it. One press on your Garmin watch starts the transcription on your Android phone, and AI feedback on what is being said reaches your wrist while you talk: a question for you, rising tension, an agreement, your name. The audio never leaves the phone; only text goes to the cloud.
If something happens to you, your family needs to know what you own and where it is. Wealth keeps the household's net worth in one currency, walks you through a short monthly review, and holds an emergency guide that is encrypted in the browser before it is saved, so the server never sees your passphrase. A copy on a USB drive opens without internet or an account.
Hosts rarely know what a young visitor actually wants to see in Mexico City. Misión is a short phone game where visitors pick what excites them, and the hosts read the answers on a private page to plan the visit. A static site with hand-drawn SVG and Web Audio, no third-party packages, and one small API that stores the answers.
Without agreed limits, every trade is decided in the moment. Portfolio Strategy Manager manages a trading portfolio and its strategies inside an agreed framework of money management and risk. The exchange key is read-only and stays on the server, never in the browser.
POC implementations, architectural reference designs, and technical decks from advisory engagements in telecom, finance, and retail — each access-gated per client.
Three years of AWS advisory work: Well-Architected patterns, serverless blueprints, security architectures, GenAI implementations, and LATAM telco transformation playbooks.
Smart home automation, IoT sensor networks, and new MongoDB Atlas Vector Search experiments are in active development. New projects published here as they ship.
