PROFILE

Wen Kokke

Worked on the input-output-hk/ouroboros-leios and IntersectMBO/lsm-tree repositories, focusing on backend development and simulation infrastructure. Delivered features such as configurable aging and cleanup policies for endorsement blocks and relay slots, improving data lifecycle management and simulation fidelity. Refactored configuration and data modeling in Haskell, enhancing clarity and maintainability. Simplified the LSM-tree codebase by removing unnecessary dependencies and hardening the Snapshot API with improved error handling and validation. Enhanced documentation using LaTeX and streamlined CI/CD pipelines with GitHub Actions. These efforts reduced operational risk, improved reliability, and laid groundwork for future extensibility in distributed system simulations and protocol development.

March 2025 performance highlights focused on strengthening data lifecycle management in simulations, refining data propagation models, and reducing operational risk by simplifying the codebase and hardening APIs. Key outcomes include configurable simulation cleanup policies with documented lifecycle, aging controls for relay slots and Endorse Blocks to improve propagation accuracy, and groundwork for future configuration features. In parallel, the LSM-tree codebase was simplified by removing AllocMonkey and the monkey sub-library, and the Snapshot API was hardened with improved error handling and naming, while CI/CD pipelines were streamlined to accelerate feedback.

February 2025 monthly summary for input-output-hk/ouroboros-leios focusing on business value and technical achievements. Key features delivered, major bugs fixed, overall impact, and technologies demonstrated are outlined below. Key features delivered: - Added eb-max-age-slots parameter to configure the maximum age of Endorsement Blocks (EBs) included in Relay Blocks (RBs); updated configuration, types, and simulation to support age-based expiration and pruning. Major bugs fixed: - Endorsement Vote Buffer Pruning Correctness: fixed pruneVoteBuffer logic to prune votes based on the correct slot number; refactored for clarity and correctness; improved simulation's vote buffer management. Overall impact and accomplishments: - Increased reliability and correctness of the endorsement flow, improved simulation fidelity, and introduced tunable aging for Endorsement Blocks, enabling safer and more predictable Relay Blocks. Technologies/skills demonstrated: - Configuration and types refactoring, simulation modeling, commit-driven development, and code clarity improvements. Top commits referenced: - 5d860cc56de1872dc3155785af8137708bbb0122: fix(simulation): clarify pruneVoteBuffer - c2592eda48ddc7b3f43b6cc3e89ef8bef0f0c115: feat(config,simulation): add eb-max-age-slots parameter
