About me
Senior software engineer based in Switzerland, with 10+ years building secure and reliable web applications and APIs.
My Story
I was born and raised in Mexico, where I first discovered programming as a teenager. That early curiosity has grown into more than a decade of professional software engineering experience.
Today, I work as a senior software engineer in Switzerland, focusing on backend services, loan management workflows, REST APIs, and maintainable product architecture.
My background spans backend systems, APIs, and full-stack development. Outside my main role, I take on freelance projects — websites, web apps, internal tools, and custom systems. I care about reliable solutions, clear decisions, and code that people can actually maintain.
What Drives Me
Security by Default
Authentication, authorization, input validation, and secure integrations built in from the start — not added as an afterthought.
Clean Code
Maintainable, readable code that teams can understand and extend without surprises.
Performance First
I optimize for real-world load times and Core Web Vitals, not just local benchmarks.
Tested and Reliable
Unit tests, integration tests, and disciplined code review that catch issues before they reach production.
Mobile-First Design
Responsive interfaces that work on any device without degrading the experience.
Clear Communication
I work directly with clients — no middlemen. You always know what's being built and why.
Beyond the Code
Cycling Enthusiast
Cycling is how I switch off. The longer the climb, the better.
Travel Explorer
I like being somewhere unfamiliar. Different languages, different food, different pace.
Cat Lover
Once you've had a cat, the house feels different without one.
