I'm a software engineer based in Málaga. I design, build, and operate end-to-end products where mobile interfaces, AI queues, billing, data, and observability behave like one living system.
I don't ship demos — I ship products with users, payments, paywalls, async pipelines, and metrics. Three of them are below.
