Worked on the okx/xlayer-erigon and okx/optimism repositories, delivering features that enhanced configurability, safety, and developer efficiency. Built project-based free gas transaction logic and configurable sequencer controls using Go, enabling flexible transaction management and tunable batch processing for blockchain applications. Introduced a configuration-driven approach to RPC forwarding, reducing risk by allowing explicit control over request routing. In the okx/optimism monorepo, developed a comprehensive knowledge base leveraging AI-assisted development and technical writing in Markdown, streamlining onboarding and reducing context-switching. Demonstrated strengths in backend development, configuration management, and documentation engineering, with a focus on maintainability and robust system design.

Jan 1, 2025January 2025: Delivered project-based free gas transactions in txpool for okx/xlayer-erigon, with new configuration options and project-scoped gas-management logic. Implemented tests validating the behavior and linked to commit d17121413e7fb1b08c048197c0802b4574e43f61 (Support specific project free gas, #236). This work enhances transaction fee flexibility for designated projects, reduces friction for project activity, and improves configurability and maintainability.
