In April 2025, Harraken developed and delivered a comprehensive OpenAPI (Swagger) specification for the Lava Network Public API in the lavanet/lava repository, documenting endpoints for blockchain data retrieval, provider information, and token supply. This contract-first approach improved developer onboarding and enabled automated tooling integration. Harraken also addressed documentation debt by removing a deprecated swagger.yml file, aligning with a centralized documentation strategy to reduce confusion for API consumers. The work demonstrated proficiency in API documentation lifecycle management, OpenAPI Specification, and YAML, with clear version control and traceability. The scope was focused but thorough, addressing both feature delivery and technical cleanup.
