Karen Ortiz
Diseño y construyo productos web impulsados por IA, de la arquitectura al último píxel.
Software Engineer enfocada en Product Engineering & Web Experiences. Diseño sistemas, componentes y agentes que conectan UX, infraestructura y AI en productos listos para producción.
- Arquitectura y desarrollo web con Next.js, Astro, TypeScript y stacks desacoplados.
- Design systems token-first y librerías npm para equipos de producto distribuidos.
- Integraciones con IA (MCP servers, LLMs, automatización) que habilitan a equipos no técnicos.










Conecto ingeniería sin la fricción habitual del handoff.
Senior product thinking
Diseño con objetivos de negocio, comportamiento de usuario y restricciones técnicas en mente.
Built to ship
Mi trabajo se traduce limpiamente en sistemas, componentes y código listo para producción.
AI con intención
Uso IA donde mejora flujos de trabajo, herramientas o valor de producto.
Colaboración sin fricción
Trabajo rápido con founders, designers y engineers a lo largo de todo el ciclo de producto.
Product & UX Engineering
Defino, diseño y construyo nuevas features o productos completos. Research ligero, UX/UI, prototipos y desarrollo fullstack en el mismo flujo.
Modern Web Experiences
Desarrollo sitios, dashboards y aplicaciones web integrando APIs, bases de datos y servicios externos listos para producción.
AI-Driven Interfaces & Workflows
Diseño y construyo interfaces context-aware donde la IA tiene sentido, convirtiéndola en agentes y automatizaciones que mejoran tu producto y procesos internos.
Design Systems & Internal Tools
Creo o evoluciono tu sistema de diseño, librerías de componentes y herramientas internas para que producto, diseño y dev trabajen sobre la misma base.
UX & Conversion Improvements
Optimización data-driven para productos activos. Analizo flujos de usuario, cuellos de botella y métricas de retención para desplegar mejoras focalizadas.
Architecture & Tech Guidance
Guío a founders y equipos pequeños a tomar buenas decisiones de stack, arquitectura e integraciones. Pensando en lo que necesitarás en 6 a 12 meses, no solo en el próximo sprint.
Empresas y equipos de ingeniería que confían en mi trabajo
Colaboro con equipos en LATAM, Estados Unidos y Europa que se toman en serio el diseño de producto, la arquitectura y la IA aplicada.
Desde startups en etapa temprana hasta equipos de producto establecidos, colaboro de forma cross-funcional con Producto, Diseño e Ingeniería para lanzar experiencias web, integrar IA en flujos reales y convertir decisiones en código listo para producción.
Algunos de los equipos y marcas con los que he trabajado en distintas industrias y geografías.
- Colaboración remote-first con founders, PMs, diseñadores e ingenieros en todo el mundo.
- Trabajo en producción: landing pages, design systems, herramientas con IA y plataformas full-stack.
- Foco en craft, performance e iteración rápida a través de zonas horarias.

Sobre mí
Las empresas trabajan conmigo por mi sentido de producto + instinto técnico.
Conecto product thinking, UX e ingeniería, para que las decisiones tengan sentido para los usuarios, el negocio y el codebase.
Me importa el craft, desde la arquitectura y el design system hasta la última micro-interacción en producción.
Defino sistemas escalables (design tokens, componentes, herramientas internas) que ayudan a los equipos a moverse más rápido.
Uso IA con intención, convirtiéndola en workflows, agentes y herramientas que realmente ayudan a los equipos a entregar mejor trabajo.
