Full-stack developer · Chillán, Chile

I build web products that solve actual business problems — not just websites that look good.

Background: biologist, teacher, developer. That combination means I diagnose before I code, communicate clearly with non-technical stakeholders, and measure results. Currently technical co-founder of Casa de la Luna — a healthcare platform in production — and taking freelance webdev jobs.

Open to working with agencies that need a developer who can operate independently and handle technical complexity without heavy direction. Especially useful for:

• Three.js / WebGL / interactive experiences (GSAP)
• Online payment integrations (Khipu, Transbank) and transactional notifications
• Full-stack Astro + React + Hono + MySQL projects
• Product analytics and MCP servers (PostHog, Model Context Protocol)
• Projects where the developer also needs to understand the business logic

I don't need a PM to talk to clients. I diagnose the problem first, then build.
