PROFILE
Vladislav Borbut
Over five months, contributed to the input-output-hk/hermes and catalyst-libs repositories by building robust backend features focused on document synchronization, API development, and system reliability. Developed parallel WASM execution and thread-local SQLite management to improve performance and stability, and implemented IPFS-based document sync protocols with envelope encoding and state machine design for distributed data integrity. Enhanced integration testing, CI/CD pipelines, and code quality, while introducing CID-based document management to streamline cross-system workflows. Leveraged Rust, SQL, and Go to deliver scalable backend solutions, emphasizing maintainability, data consistency, and efficient resource management across evolving distributed systems and APIs.

Jan 1, 2026January 2026 monthly summary focusing on Hermes repository work and cross-system integration with Athena. Key improvements include CID-based document synchronization and management, enabling add/retrieve operations via Content Identifiers (CIDs), and the introduction of return_cids and retrieve_doc APIs to streamline document workflows. The changes also addressed stability and reliability through targeted bug fixes and quality improvements across the SMT-backed storage and API surface. The work enhanced data integrity, cross-system collaboration, and maintainability, with a clear path to scalable document handling.

Dec 1, 2025December 2025 focused on delivering robust document synchronization across IPFS and Hermes. The team shipped a standalone IPFS doc-sync protocol with envelope-based encoding/decoding and a state machine, alongside Hermes document sync with local SQLite persistence, enhancing reliability, data integrity, and retrieval performance. These changes deliver concrete business value by improving cross-system interoperability, reducing duplicate entries, and enabling faster, offline-friendly access.
