Preparing the orb and voice session controls.
I build products where AI, systems, and interface design meet.
I'm from Rosario, Argentina. I've been obsessed with solving problems since I was a kid. Math olympiads, not because anyone pushed me, but because I loved the challenge. The solution is never the hard part. The approach is everything.
At 21 I dropped out of university to start a Bitcoin mining company. It worked. We scaled fast, and that itch to build never went away. So I taught myself to code because I refused to keep delegating the most important part of building a company.
Today most of my time goes to Verelyn, a newsroom built around one reader. Flare, my social brain, is live on iOS. Privé lets creators sell and get paid without leaving Telegram. Different problems, same bet: software should act before you ask it to.
Work
Verelyn
ActiveJournalist agents that write your morning briefing
The newsletters you pay for are good, and they were written for thousands of people at once, which is why most of them sit unopened. Verelyn is a newsroom built around one reader. Its journalist agents read your sources every morning, fold four reports of the same thing into a single event with its sources attached, weigh each one against what you actually have riding on this week, and send one briefing at 07:00. Every item is signed by the agent who wrote it and carries its sources, including where they disagree. Most events get dropped and the reason is recorded, so a miss can be answered for. Hayes covers the first beat, startups and AI. Live since August 2026, and the first reader paid twelve days after the first commit.

Flare
ActiveYour social brain, voice-first
An agent that keeps you close to your friends. It tells you what they're up to in near-real-time, and telling it about your life is the same act that feeds theirs. The whole product is one conversation: you open it and the Orb is already talking, your answer is your check-in, and it closes by pointing you at a real human. No likes, no comments, no feed of strangers. Live on iOS. I designed and built the system: 29 database tables with row-level security, 23 Edge Functions, three AI agents on a two-layer pipeline.

Privé
ActiveTelegram-native storefront for creators
Creators sell digital content, video calls and VIP group access without leaving Telegram. They get paid through Mercado Pago, crypto or bank transfer, and the money lands in their account, never mine. Privé charges 0% on every plan and every method, and makes its money on the Premium subscription instead of a cut of each sale. Bot, mini app, payment rails and the fee engine are all mine.

Inception
ActiveBitcoin mining farm with over 500k in ASICs
Started this at 21. We host and operate our own mining rigs, built the infrastructure, automated the operations, and scaled it into a real business. Still running today, still generating revenue, and it funds everything else I build.

How I got here
How I think
Problems are common in everyone's life, but not everyone knows how to solve them. For me the problem itself is just a thing that needs solving. The real challenge is the approach.
When I approach a problem I divide and conquer. First I try to understand all the possibilities — all the doors that could open, the things I don't know yet that might turn out right or wrong, that could bring bigger problems or reveal a solution. I examine as many paths as I can before I start moving. Then I go for the most effective way through.
This is why I started playing chess. I always knew how to play, but I've come to believe it's a majestic game. With 16 pieces and 64 squares there are more possible positions than grains of sand on Earth. That combination of simplicity and infinite complexity is what draws me in. Pattern recognition, calculated risk, knowing when to trade material for position. It maps directly to building products. I'm still a beginner — still blundering queens and hanging pieces — but the board never lies, and every loss is a lesson.
What I build with
I'm self-taught. I learned to code because I refused to keep delegating the most important part of a startup. Today I build with:
React
TypeScript
Tailwind
Next.js
Expo
Supabase
Postgres
Fastify
Drizzle
Gemini
ElevenLabs
Vercel
Resend
Stripe
Telegram
React Query
PostHog
Sentry- Mobile
- Expo and React Native, iOS-focused, shipping to the App Store with OTA updates via EAS
- Frontend
- React, TypeScript, Tailwind, Next.js for web
- Backend
- Supabase (PostgreSQL, Auth, Edge Functions, Storage) for Flare and Verelyn; Next.js 16 and React 19 on Vercel for Verelyn's site and product; Fastify with grammY and Drizzle on Postgres for Privé
- AI
- Google Gemini for Flare's agent system, ElevenLabs for voice, the Vercel AI Gateway for Verelyn so each task goes to the model that fits it — cheap ones to rank in bulk, better ones to explain
- Ingestion and delivery
- Firecrawl to read the web for Verelyn, Resend for the 07:00 email, Stripe for billing
- Design
- Custom design systems with design tokens, Skia shaders for the Aura Orb, component libraries
- State
- Zustand for client state, React Query for server state
- Observability
- PostHog for product analytics and session replay, Sentry for errors
Beyond code
Photo with Messi
I'm from Rosario, same city where Messi is from. Back in 2005 or 2006, he came to show a few tricks at Casa Amarilla, where I was training football. Of course, back then he was just "La Pulga," a young kid who had just started playing for Barcelona.
Chess
Just getting started on my chess journey. Still blundering queens and hanging pieces, but every loss is a lesson. The beauty of chess is that the board never lies. It rewards patience, pattern recognition, and thinking two moves ahead. I'm hooked.
Reading
I read a lot. Strategy, psychology, history, fiction. Anything that changes how I think about the world. A few favorites:
- Zero to One — Peter Thiel
- The Art of War — Sun Tzu
- 1984 — George Orwell
