About

I build applied AI, automation and data solutions for organizations. My work has moved through research, finance, data, public-sector transformation, service architecture and AI implementation. That path shaped how I work: I understand the problem, design the solution and take it to execution.

Today I am a partner and CTO at INPLUX and a partner at TENSOR. From there we build AI products such as Tribai and Kelsen, and bring AI and data to public agencies, universities and companies. I also teach AI at EAFIT and ESUMER. Before that I led AI and automation initiatives at PRGX LATAM. I am an economist, with an MSc in Economics from EAFIT, and a PhD candidate in Engineering at Universidad Nacional de Colombia.

Notes

  1. Por qué Tribai

    2026-05-02

    El conocimiento tributario era un bien escaso. Ya no lo es. La pyme paga la diferencia.

  2. El PDF de cuatrocientas páginas era un workaround. La plataforma viva ya no lo es.

  3. En Colombia, la negligencia digital del Estado es invisible — y por tanto sin costo. Un observatorio cambia eso.

  4. Los laudos arbitrales vinculan como sentencias, pero no se distribuyen como sentencias. Esa asimetría tiene precio.

  5. Por qué Kelsen

    2026-05-04

    El derecho colombiano corre sobre una pirámide, no sobre precedentes. La IA legal de Colombia tiene que ser distinta.

  6. Una nota corta sobre por qué refactoricé el sitio personal a una sola página.
