About me

Hands-on engineer and architect with 14+ years across software, data and mobile. I build AI products and full-stack platforms from idea to production, combining architecture with delivery. Based in Spain; available now for remote contracts through ICC, including fixed-price projects.

AI engineering and agentic workflows
I build AI products from requirements through production. At MISE Health, I built the AI service from scratch: document ingestion, OCR, structured extraction, long-document batching, staged summarization and partial-response merging. Evaluation combines schema checks, LLM judges, human review and thousands of test cases. I self-hosted Qwen3-VL-8B on Hetzner GPU infrastructure with queues and circuit breakers.

AI toolkit: LangChain, LangGraph, Mastra, Temporal, open-weight models, Codex, Claude, Pi and Orca. My engineering workflow uses specifications, delivery plans, milestones, TDD and frontend mocks, with hands-on review and validation of agent output.

Software and solutions architecture
14+ years across backend, full-stack and mobile engineering. I built QS Project from scratch and owned architecture and delivery. Backend: Java (including Java 21 and 25 in production at QS), Spring Boot, Spring Cloud, microservices, TypeScript, Node.js, NestJS, Express, REST APIs and webhooks. Data: SQL/NoSQL, MongoDB and Redis; integration of multiple data sources and MDM concepts. Workflow- and state-based row-level permissions at QS and MISE.

Full-stack, mobile and infrastructure
React, Next.js and TypeScript for full-stack platforms; Swift, SwiftUI, UIKit, iOS/tvOS and React Native for mobile products. Experience includes SkyShowtime, EIDA digital tools and payment/API integrations. AWS, Google Cloud, Hetzner, Docker, CI/CD and observability.

Technical leadership and consulting
At EIDA, I progressed from Software Engineer to Solutions Engineer and directly managed 10 people across frontend, backend and QA. At QS, our platform team supported other engineering teams. I translate stakeholder needs into technical decisions and working products, and deliver AI adoption workshops and consulting through ICC and Agentic Train.

Education: Master's in Big Data, European University Miguel de Cervantes (2020–2021); Master's in Mobile Development, Pontifical University of Salamanca (2014–2015); Computer Engineering studies, University of Extremadura (2007–2011).

Available immediately, full-time and remotely from Spain. Company-to-company engagements through ICC; hourly or fixed-price projects scoped around deliverables.
