Deep understanding of async programming, concurrency models, and distributed system design. Solid command of SQL and relational schema design, ideally using PostgreSQL. Proven experience developing RESTful APIs and working in event-driven architectures. Excellent debugging, communication, and problem-solving skills. Nice to have: Experience with e-commerce APIs (Amazon SP-API, Shopify). Familiarity with event-driven workflows, backpressure management, and idempotency. Exposure to GCP, Kubernetes, or container orchestration. Understanding of durable state management and crash recovery 100% remote position within the EU, offering flexible working arrangements.
