About Me
I’m Liliana Castellanos, a solution architect and product engineer with over a decade of experience driving business innovation through technology.
From Cuba to Chile, from developer to the sky, I’ve built systems that scale, integrate, and adapt. Not by throwing everything away, but by understanding what works and making it better.
- Connecting fragmented tools and teams into coherent ecosystems
- Automating processes to reduce cost and improve decision-making
- Bridging the gap between technical execution and strategic business needs
I lead with empathy, code with purpose, and build with a deep understanding of both business and people. Whether working in large organizations or early-stage startups, I bring clarity a la complejidad
