René
Mujica.
Software engineer, quietly building on the internet.

Subject
Twenty-seven years writing software (fifteen getting paid to). Started with games, founded beender in 2013, drifted through consumer apps and fintech, and landed at Justo. The rest is in the ledger.
Obsessed with travel, transport, photography, hardware, scuba diving, and gaming. Currently tinkering with:
- Ittineria.com — because the only thing worse than a bad vacation is letting an AI plan it for you. Mobile travel planner. You drive, AI assists.
- Atendi.cl — because your tía’s manicurist deserves better software than your bank. AI-powered appointment scheduling on WhatsApp.
- Postcards — the only app where “slow delivery” is a feature, not a 1-star review. Messaging app with intentional delay.
