๐ Pereira, Colombia ๐จ๐ด | ๐ค CTO & Co-founder at Dailybot (YC S21) | ๐ค Founder of Pereira Tech Talks
๐ Full CV ยท ๐ฏ Portfolio
15+ years shipping digital products โ from early-stage startups to YC-backed SaaS serving thousands of teams. Currently scaling Dailybot, going from programmer to orchestrator โ learning to direct, automate, and build real workflows with AI agents โ and shipping tools for myself, for my local tech community back in Pereira, and for the world.
"Build, ship, share." I solve my own problems with code, then open-source whatever might help someone else. Communities grow when builders show their work.
