About

Engineer mindset, product delivery

I'm Christian Eliel — mobile and full stack developer, with a postgraduate degree in Data Science. I treat every project as a product: real users, real constraints, measurable results. I like owning the whole path — architecture, code, integration, deploy, and the part nobody wants (store review, monitoring, maintenance).

Everything I put in production — including this site — runs on free-tier infrastructure with a strict Content-Security-Policy, no trackers and automated validation on every push. Cost and security discipline aren't features to me; they're defaults.
