PROFILE
David Li
Over seven months, contributed to dydxprotocol/v4-chain by building and optimizing backend features focused on financial data accuracy, API usability, and system reliability. Developed and enhanced endpoints for PnL aggregation, trade history with cumulative profit and loss, and subaccount management, using Go, TypeScript, and PostgreSQL. Implemented recursive data pipelines, daily and hourly aggregation, and governance-enabled transfers, while addressing edge cases and improving error handling. Refactored APIs for performance and maintainability, expanded test coverage, and resolved bugs affecting data integrity. This work enabled more accurate reporting, faster analytics, and robust risk tooling for traders and business stakeholders within the protocol.

Dec 1, 2025December 2025 monthly summary for dydxprotocol/v4-chain: Delivered significant performance and resilience improvements to Subaccount PnL data retrieval. Implemented optimized subaccount ID resolution to speed up /v4/fills/parentSubaccount queries, and enhanced the PnL controller to return an empty array when no data exists for a parent subaccount, preventing unnecessary errors. Added tests to validate behavior and guard against regressions. These changes reduce latency, improve reliability in edge cases, and strengthen subaccount PnL accuracy for traders and risk tooling, delivering measurable business value.

Nov 1, 2025November 2025 (dydxprotocol/v4-chain) focused on strengthening governance, improving reporting accuracy, and enhancing subaccount handling reliability. Key work included delivering governance-enabled transfers, correcting SQL-based transfer filtering to respect limit parameters, and fixing PnL aggregation for mid-day-created subaccounts to ensure precise parent/child reporting. These changes reduce risk, improve financial reporting fidelity, and enable more secure, auditable transfers across accounts.

Oct 1, 2025Month: 2025-10 — Delivered key features and performance improvements for dydxprotocol/v4-chain. Key feature deliveries include per-market fee discounts for CLOB pairs, implemented with proto definitions, keeper logic, and message handlers, and integrated active discounts into the perpetual fee calculation. PNL endpoints were significantly optimized with hourly/daily aggregation, improved pagination and filtering, and expanded test coverage. No major bugs fixed this month. Overall impact: enhanced trader value through discount-driven fee economics and faster, more reliable PNL analytics, supporting higher throughput and better decision-making. Technologies demonstrated: proto definitions, keeper logic, message handlers, on-chain/off-chain integration, database query optimization, data aggregation, pagination, and test automation.

Sep 1, 2025Month: 2025-09 — dydxprotocol/v4-chain. This period delivered substantial enhancements to PnL data availability, along with targeted bug fixes that improve data integrity and reliability for business decisions. Key features delivered: - PNL Data Pipeline and Retrieval: Implement recursive PNL computation and expose PNL data via API endpoints. Added a new PnL calculation job and API for subaccounts and aggregated data with daily aggregation option. This enables near-real-time PnL visibility across subaccounts and consolidated views for executives and risk teams. Major bugs fixed: - PNL Calculation Bug Fix: Fixed incorrect PnL calculation in update script, refined net transfers and trade cash flows, correctly handled null subaccount IDs and trading fees, and updated tests. This improves data accuracy and reliability of PnL reporting. Overall impact and accomplishments: - Provides accurate, timely PnL data for subaccounts and aggregated views, enabling better financial reporting, reconciliation, and decision-making. Improves risk management and operational efficiency by reducing data discrepancies. Daily aggregation supports near real-time analytics. Technologies/skills demonstrated: - Recursive data processing and data pipeline orchestration - API design and exposure for subaccounts and aggregated data - Batch job creation and scheduling - Edge-case handling (null IDs) and test-driven validation - Daily aggregation architecture and data modeling for PnL Top business value: - Faster, more accurate PnL insights drive informed decisions, reduce reconciliation time, and improve risk controls across the organization.
