Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I'm Horacio Gastón Lagándara, a Software Architect and Fullstack Developer with 20+ years of solving complex problems across media, e-commerce, retail, transport, payment systems, and more. I'm technology-agnostic by nature and comfortable with many paradigms and languages—from C/C++, Smalltalk and Java to JavaScript, Node.js, and a detour through Scala. On the frontend I've moved from JSF, Wicket and Angular to Vue.js, and on the styling side from vanilla CSS to Tailwind. If it solves the problem elegantly, I'll learn it. I'm not just about the code—I'm about the team, the architecture, and the people behind the product. I've led, mentored, and helped clients, and I've put out a few fires along the way. I grew up with these technologies, watched them evolve, and I know how to get from concept to production. Outside work I enjoy yoga, weight training, cooking experiments, and long walks with my dog.…I'm Horacio Gastón Lagándara, a Software Architect and Fullstack Developer with 20+ years of solving complex problems across media, e-commerce, retail, transport, payment systems, and more.
