Specialized full stack developer based in Colombia. I spent fourteen years keeping hardware, networks and servers running before I moved into software in 2022. Now I build web products end to end, from the first call to the client's own domain.
- 🔭 Now: Web & SEO Developer at DigitalYa. I build and ship websites for law firms and professional practices, and I also take freelance projects as Daev.
- 🧱 Before: Technical Lead on Agro Ledger, a plant-to-batch traceability platform for a regulated crop at Colombian Cannabis Center.
- 🎯 Strongest at: backend with solid business logic, and taking a project from idea to production, with the domain and the metrics.
- 📚 Learning: the Google UX Design Professional Certificate and Anthropic's Claude Code 101 (Coursera).
