PROFILE
Luis Herasme
Luis Herasme contributed to the Blobscan/blobscan repository by building and refining backend and API features focused on reliability, security, and data efficiency. He implemented binary data support across multiple storage backends, using TypeScript and Node.js to handle buffers and optimize storage performance. Luis introduced API key authentication for sensitive endpoints, improved rate limiting with Redis, and enhanced analytics configuration to ensure data integrity. His work included refactoring legacy code, updating documentation, and streamlining environment configuration. By addressing both feature development and bug fixes, Luis delivered maintainable solutions that improved system observability, payload efficiency, and the overall developer experience for Blobscan.

Jun 1, 2025June 2025: Blobscan/blobscan delivered comprehensive binary data support for blob storage. Refactored storage backends (GoogleStorage, SwarmStorage, FileSystemStorage, PostgresStorage) to store data as Buffer with content type application/octet-stream, updated file extensions to .bin, and implemented URI-extension-based parsing. Normalized inputs to accept hex strings or buffers. Reduced base64 conversions, improved performance and memory usage, and updated tests to reflect .bin usage. This work lays the groundwork for reliable binary asset handling and smoother downstream processing across services.

May 1, 2025May 2025 monthly summary for Blobscan/blobscan focused on reliability, security, and payload efficiency. Key work includes a reliability fix for the Feedback API rate limiting by refactoring to ioredis and consolidating logic into the feedback endpoint, improving Redis error handling and removing legacy middleware; and a security/payload improvement by introducing a dedicated blob data retrieval endpoint with API key authentication and an environment flag to control its availability, ensuring blob data is no longer returned in standard API responses.

Jan 1, 2025January 2025 monthly summary for Blobscan/blobscan: Delivered a new Timestamp Display Toggle to switch between relative time and absolute date-time across blobs, blocks, and transactions, significantly improving data clarity and user confidence. Strengthened API safety with a ContextScope type in createTRPCContext, restricting scope to 'web' or 'rest-api' to reduce misconfigurations and ease maintenance. Implemented UI polish and refactors (onChange prop usage for TimestampToggle, tooltip simplifications) along with targeted stability fixes (timestamp table cell height, loading skeletons) to improve rendering consistency. These changes drive better data interpretation, safer API usage, and maintainable code, enabling faster future feature delivery and a smoother developer experience.
