I build AI-powered websites and automations that turn messy, manual processes into useful products. My work sits between applied AI, automation, data products and interactive experiences.
Currently I am studying Design and Digital Entertainment Engineering and building real tools with TypeScript, Next.js, Python, SQLite, n8n and local AI. I am also a co-founder of DAZERIT, a small software and automation studio in Medellín.
- Websites and landing pages with a built-in AI assistant that answers visitors and captures leads (Astro, React, Next.js).
- Business automations with n8n, Make and Zapier: forms, Google Sheets, Excel, email, CRM and WhatsApp.
- AI chatbots and assistants for web and WhatsApp (Claude, OpenAI).
- Dashboards and internal tools on Postgres and Vercel.

- Real data and honest limitations; no invented metrics.
- Secure defaults, tests and documentation that another person can actually follow.
- AI where it is useful, with deterministic code for calculations and critical decisions.
