What I'm looking for

I'm looking to build and operate production-grade full-stack and applied AI products, especially LLM integrations, RAG, autonomous agents, scraping, and data pipelines. I value ownership from requirements through production support, cloud systems, and measurable performance improvements.

I've built and operated PalaComparer, a live padel- and tennis-racket price-comparison platform with resilient multi-retailer scraping, price-history tracking, deal detection, SEO/GEO optimization, and GA4 analytics. I also run a self-hosted AI-agent platform 24/7, orchestrating scheduled scraping, monitoring, content generation, and message delivery workflows.

At Capitole, I optimized mission-critical payroll processes, resolving long-standing timeouts and improving query performance by up to 95%. Previously at Hiberus, I improved a critical payroll process by 70% for a Tier-1 banking client while building .NET 8 microservices on AWS and observability with Datadog.

Across GLS Spain, Ferchau Engineering, and Eikondata, I've delivered .NET applications, REST APIs, cloud deployments, databases, and front-end features using React and Angular. I focus on building and operating reliable products end-to-end, from requirements through production support.
