Evidence

I am currently focused on refactoring the transaction pool and implementing a fork-aware version to address the issues outlined in #1202 issue. The related pull request #4369 is under review. The design and approach are detailed in this short top-level design note. Following the knowledge-sharing sessions I conducted within the Node SDK team, I authored a technical note on the fork-aware transaction pool. Additionally, I have started working on a transaction test tool designed to facilitate local and QA tests of the transaction pool. The follow-up work is planned here. This work improves transaction handling under forks, a critical aspect of parachains performance and resilience.

The most important lessons I have learned from this work include:

• Building a generic transaction graph for efficient transaction pool management,
• Addressing the challenge of preventing block builder starvation, ensuring smooth non-empty block production.

Additionally, I have minor contributions to Omni-Node, primarily by focusing on chain specifications and genesis configuration across various runtimes through reviews. Some related small PRs include: #4678, #5813, and #4739.
