PROFILE

Daniel Fernandez Arias

Worked on the qdrant-cloud-public-api repository, focusing on backend API development and feature flag management using Go, Protocol Buffers, and gRPC. Over three months, delivered three features including a cleanup of deprecated cluster feature flags, a refactor to remove the GetFeatureFlags API endpoint, and an enhancement to the UpdateSpace RPC enabling dynamic account ID targeting for multi-tenant flexibility. The technical approach emphasized reducing API surface complexity, improving maintainability, and supporting centralized feature flag control. Code quality was maintained through systematic linting and traceable commits, ensuring that architectural changes aligned with evolving roadmap requirements and future scalability needs.
