About
I'm a senior software engineer and tech lead with over 8 years designing and shipping backends, microservice architectures and DevOps pipelines. I've led teams and strategic projects at companies like Pulselive, BASF and Orange, defining end-to-end solutions and guiding the team on best practices, code reviews and key technical decisions.
My home turf is high-performance backend with Java and Spring Boot, messaging with Kafka and RabbitMQ and patterns like Event Sourcing and CQRS, all on the cloud (AWS, Azure) with Terraform, Docker and Kubernetes. I'm obsessed with automation, CI/CD and building scalable, observable and maintainable systems with solid test coverage.
But I don't stop at the server: I also design and ship my own products end-to-end. In my spare time I build mobile apps (React Native / Expo) and websites, handling everything — product, UX, calculation engine, data and store publishing. A sample:
> IPCHECK
Is your rent increase legal? Applies the official index (IRAV/IPC, Spanish Housing Law) read from the INE and drafts a reply letter.
React Native · Expo> mihipoteca
Financial calculator: pay down your mortgage or invest? With Spanish taxation, a tested calculation engine and charts.
React Native · Expo> EditPDF
