At Mercadona Tech, I built digital solutions in an Agile XP team for Spain’s largest supermarket chain. I optimized warehouse employee management processes, reducing operational time by 50%.
As a freelance Full-Stack Engineer, I design, build, and operate cinematicstatephotography.com end to end. The storefront uses Next.js, Payload CMS, Neon Postgres, Vercel, and Stripe Embedded Checkout, with five-currency pricing and webhook-driven Printful fulfilment.
I’ve built a custom multi-agent development system on Claude Code and use an AI-assisted spec-to-plan-to-implement-to-review workflow for test-backed delivery. Earlier, at Nexum AG, I developed REST and GraphQL APIs for e-commerce clients and improved API response times by 20% using Elasticsearch.
