About
EngineerFirst
Eight-plus years building software end to end — and leading the teams that build it, without stepping away from the code.
I'm a computer engineer with 8+ years across the full product cycle — designing, developing, deploying and operating cloud-native applications, and leading the teams that build them.
My core is TypeScript and modern frontend work — React, Next.js, Angular, Vue — sitting on Node.js backends, REST APIs and microservices deployed with Docker and CI/CD across AWS, GCP and Azure. I care about the parts that only show up in production: performance at scale, honest testing, observability, and code that the next person can read.
I've done that work in very different settings: cloud DICOM viewers at IdoniaHealth, enterprise e-commerce and mobile projects at Hiberus, athlete platforms funded by NextGenerationEU at the Spanish Royal Judo Federation, and — since 2022 — as Founder and CTO of Oniria Studios, where I still write code every day alongside freelance client work.
AI runs through both sides of that. I integrate and orchestrate LLMs inside the products I build, and I use Claude, GitHub Copilot and Cursor as part of everyday development. My ongoing PhD in explainable AI applied to biomechanics keeps me honest about what these models can and cannot be trusted to do.
How I Got Here
Computer Engineering & Game Development
Two degrees at Universidad San Jorge — Computer Engineering (2020) and Video Game Design & Development (2021, graduated with distinction). Systems thinking on one side, users and interfaces on the other.
Hiberus Tecnología — Software Engineer
Three years at one of Spain's largest technology consultancies: one year in e-commerce, two in mobile development for enterprise clients. Full-stack work with agile methodologies, CI/CD and REST API integration — where professional engineering habits were formed.
IdoniaHealth — Frontend Tech Lead
Technical reference for cloud-based DICOM medical image viewers. Frontend architecture, API integration and performance at scale, under GDPR and clinical data-security constraints — plus CDTI-funded R&D bringing AI into the imaging pipeline.
Oniria Studios — Founder & CTO
My own company, now 4+ years old, where I lead technology and still ship code. End-to-end delivery of cloud-native applications for clients: microservices and REST APIs, development, deployment, QA — and mentoring the developers who build alongside me.
A Senior Engineer Who Also Leads
Full-stack in TypeScript and Python, comfortable from the database schema to the deployed interface, across AWS, GCP and Azure. I lead and mentor teams without stepping away from the codebase — and I use AI tooling (Claude, GitHub Copilot, Cursor) as part of everyday development.
