I teach myself the hard stuff, and leave it running

SaaS for restaurants

I didn't build another POS: the restaurant already has one. Divídela solves what that system ignores, the moment of the bill at the table: order and split from your phone, in real time. It works alongside what they already use instead of replacing it. Built end to end: product, design, and code. I piloted it with a real restaurant during 2026 and today it's in commercial launch, looking for its first paying customers.

Campaign landing page

The official page of the “Súmate a lo que nos une” campaign, live today as the home page of teleton.cl. I conceived, designed and built it end to end: modern, simple and elegant, with a countdown, the 2026 ambassador and the anthem playing right on the page. Behind it I built a four-piece system across three repositories: the landing, an AI bot that answers by text and voice with its own backend, an admin panel with two-factor login and the panel the press team uses to publish news. The version with the bot is finished, tested and documented, and reaches teleton.cl with the development team's next deploy. From the same launch: I handled the anthem's release as a single on Spotify (Teletón Music, with Princesa Alba and SINAKA) and designed and ran the meeting with content creators, with script, rundown and a presentation built as an HTML page.

Publish to the landing without touching code

So the press team could update the campaign landing's news without depending on me, I built a separate panel: they paste the link of a teleton.cl article, order a queue of three to five, change the cover and publish, and the panel commits straight to the landing's repository through a GitHub App. It opens with a PIN plus a second factor, has an edit lock so two people never overwrite each other, optimizes the photos and emails a notice on every publication. In production since August 2026, with continuous integration, secret scanning and over a hundred automated tests.

Self-reporting social analytics

Internal dashboard that unifies the analytics of the foundation's social networks and website (7 platforms connected today). I fixed the data first (5 root causes, 23 fixes, a 4,298-row migration), then automated the output: an AI assistant summarizes the metrics and sends a weekly report on its own, and the monthly report comes out as a print-ready editorial deck. Each report includes paintings I curated personally, so the numbers arrive with something human. In August 2026 I added a campaign trend meter: it follows on TikTok and Instagram the videos other people create with the anthem's sounds, measures plays and new videos per day, reads the comments and classifies their sentiment with AI (without storing authors), and every morning sends the team a briefing with what's new, never repeating what was already reported. No official API: public data and a browser robot that runs three times a day.

Quoting sponsored posts on the institutional networks

Internal tool to estimate the value of company posts on Teletón's social networks: a guided eight-step flow that builds packages or custom quotes, converts to pesos at the day's exchange rate and generates the PDF and the approval email. It started from my own research of market rates. It stayed a working prototype in React (January 2026) and never reached production.

From an AI demo to the official song

When it was born in 2022, the Digitón was just Teletón's livestream. In 2025 I installed the concept that the Digitón is everything digital (social media, site and stream) and gave it a sound identity: the official anthem wasn't landing with younger audiences, so I gave myself the mission. I composed a demo with AI on Udio, and from it came “Digitón (Teletón 2025)”, recorded by Gino Mella: the first anthem it has ever had. The result: the most successful Digitón since its creation.

Editorial AI innovation

As Director of Digital Content at Radio ADN I conceived and produced the country's first interview with a historical figure recreated using artificial intelligence. Amplified across the Prisa Media network (Los40, Concierto, Futuro, Corazón, RadioActiva).

AI adoption in the Communications team

I designed and taught a 75-minute hands-on workshop for Teletón's Communications team: when to use Claude, Claude Cowork or Claude Design (the two-minute rule), how to write a professional prompt, and a team exercise that turns raw notes into a complete press kit, with fictional data. A 29-slide deck, five prompts ready to use the next day and a prompt library per project so the habit doesn't stay in the talk.
