Software engineer · Madrid
I build software, then take the system apart until the mechanism is something I can explain.
Madrid is home. About four years of the work has been professional product engineering: healthcare and electronic records, dense interfaces, APIs, realtime, authentication, billing, interoperability, and the compliance-shaped edges around them.
The direction I want is architecture. Design the system, understand the layer under the framework, and use agents where they speed the implementation without handing them the decisions.
