I'm a software engineer at One Call based in Basel, Switzerland. I build and ship production software end to end, and help bring AI workflows into day-to-day engineering on a large healthcare platform.
Outside of work, I build things that help real people: The Israel Guide, a GEO-optimized booking product; SAS Creator, a browser agent that automates company registration in Mexico; and Sublify, a native macOS app for subliminal messaging.
Background
I grew up in a city near Mexico City and started playing the piano when I was seven. Franz Liszt quickly became my favorite composer, a lifelong obsession that eventually inspired the name Lisztos. After competing internationally and winning a national first prize, I decided to step away from the stage and discover what awaited me beyond Mexico. That search took me through the US and the UK before I landed in Germany, where I studied Wirtschaftsinformatik (Business Information Systems) at TU Berlin.
In Berlin, I took my first steps in the industry as a working-student engineer at Almondia and then at Setting.io, a proptech startup that showed me how much fun a fast, close-knit Berlin startup team could be.
A move to Munich brought me to Demodesk, where I joined as an intern while writing my bachelor thesis on decentralized identity. After graduating, I stayed on full-time and grew into a full-stack engineer and team lead, coordinating delivery across product and support.
Later, a former colleague brought me over to Innovandio. Working across enterprise clients meant jumping into unfamiliar stacks quickly, designing CI/CD pipelines from scratch, and leaning into AI-assisted development early to ship faster.
After taking time off back in Mexico to reconnect with my roots, One Call reached out to bring me on board to help modernize their platform and accelerate AI adoption across engineering.
Today, I'm settled in Basel, enjoying the rhythm of Switzerland and a culture built around craft and precision.
