Worked on the rosetta-models/common-domain-model repository, delivering eight features and resolving critical bugs over three months. Focused on enhancing financial data models and settlement workflows, the work included updating pre-trade processing documentation, refining bond function operations, and improving security settlement event qualification. Leveraged Haskell, Java, and JSON to optimize algorithms, restructure data models, and streamline code by removing deprecated types and validation rules. Introduced governance templates and standardized contribution processes to support compliance and collaboration. The technical approach emphasized release discipline, cross-team communication, and robust documentation, resulting in more reliable financial processing and improved onboarding for downstream systems.

Jun 1, 2026June 2026 monthly summary for rosetta-models/common-domain-model: Delivered core improvements to Bond Function CDM, enhanced JSON data modeling, and advanced ISDA governance scaffolding, while aggressively cleaning the codebase to remove deprecated types and FpML validation rules. Key integration work included merging master into feature branches with updates to bond operations (cancellation, rate changes, adjustments, repricing, and roll) and resolving merge conflicts across bond output resources. Data contracts and inputs were strengthened with updated InstructionComposition types, effective date handling, and global keys, and inputs aligned for product keys and business day conventions. Governance scaffolding for ISDA Master Agreement Elections and supporting issue-tracking/docs were established to improve compliance and cross-team collaboration. Overall, the work increased reliability and speed of CDM bond processing, reduced technical debt, and improved governance readiness.

Apr 1, 2026April 2026 — rosetta-models/common-domain-model: concise monthly summary focusing on delivered features, bug fixes, and overall impact for performance reviews. Key features delivered: - Pre-trade processing model documentation updated to document new attributes (identifier, comment, dividendTerms) for AvailableInventory and AvailableInventoryRecord. - Corporate actions settlement terms added, including cash settlement type and currency specifications. Major bugs fixed: - Numerical stability and performance improvements for exponential, sqrt, and log functions. Overall impact and accomplishments: - Clearer data model documentation, more reliable financial calculations, and richer corporate-actions data enabling safer downstream processing and faster settlement workflows. Technologies/skills demonstrated: - Documentation discipline, release-driven development with traceability (PRs and commits), numerical optimization, and cross-team collaboration in the common-domain-model project.
