Developed and delivered the OrderRoutingMode field within the FIX42 data dictionary to enhance order routing configurability and support both standard and best-execution strategies. This work, committed to the paxosglobal/docs-mintlify repository, focused on improving trader control and compliance alignment by enabling users to specify routing preferences directly in the FIX protocol. The implementation involved detailed data modeling and comprehensive documentation updates, utilizing XML for the data dictionary and Markdown for technical documentation. No major bugs were addressed during this period, with efforts concentrated on feature delivery and maintaining alignment with project requirements for API integration and protocol consistency.
