About Adria
Senior software engineer and backend architect with 13+ years designing, building and operating event-driven systems at scale. I take ownership end-to-end, from domain modelling (DDD/CQRS, hexagonal architecture) to the AWS/Kubernetes infrastructure it runs on, shipping clean, well-tested, maintainable services.
My focus is high-volume e-commerce, marketplaces and logistics. At Kaufland e-commerce I build and operate Kaufland Shipment Solutions (~200K new shipments/day) and re-architected the customer-seller email-proxy (fully async, DDD/CQRS, LLM + rspamd filtering). At PromoFarma by DocMorris (Zur Rose Group) I built backend services in a federated GraphQL architecture with consumer-driven contract testing.
Core stack: TypeScript/Node (NestJS), Go, AWS, event-driven architecture, GraphQL, with a strong PHP/Symfony foundation (10+ years). AI-augmented engineering (LLM-based developer tooling).
Available for B2B contract work: remote on EU hours, open to occasional onsite, billed via my Spanish company.
