Alex Rubia
Hi, I'm Alex. I've been writing software since 2007: I started with an online store on a hand-rolled MVC framework, co-founded a startup, led teams as CTO, and today I work on the backend at Postman as a Senior Software Engineer.
I like things simple, not simplistic: code that reads well, reliable systems and products that solve real problems. AI is now part of my daily work: I explore faster, iterate more and spend my time on the decisions that matter.

skills
I'm passionate about software engineering: understanding the problem, designing the system and leaving it running in a way others can maintain. And I have a strong infrastructure background: from running my own Apache and MySQL servers in 2009 to AWS, Kubernetes and serverless today.
