Sep 1, 20252025-09 Monthly Summary (left-curve/left-curve): Focused on deployment stability, data integrity, and pricing accuracy. Key deliveries across CI/CD, data migration, trading SDK, and UI formatting; all aimed at reducing operational risk and enabling faster, more reliable releases. Key features delivered: - CI/CD: Update Node.js versions across portal deployment, SDK docs deployment, SDK PR checks, and Storybook deployment to improve stability and enable newer features (commit 7f01ec062bb618048ed0906ad583ab4e4aacfe11). - Data Migration: Global migration strategy for useStorage with string-key migrations and a fallback path; remove outdated v1.5 migration logic to prevent confusion and reduce code (commits 4a7fa5c210e3c6821eaaf2056ddd0dbb40776f3a, da3860d269393bc286e0f0ba6c1aab4f331046d2). - Trading/Indexer SDK Improvements: Remove deprecated orderType field and refine batch order updates to select Bid/Ask schemas correctly based on buy/sell (commits 35ced13a0a725fe45ba06773089b35cf91183adb, ffb418ebba79b4d782e770098e3f6142c1711ddf). - UI Number Formatting Improvements: Improve number formatting logic to enforce valid min/max fraction digits and fix typos affecting precision (commits f4a737f8e5a22a2870d7adec85d327561c506118, 8a7ace4ca74a9726bfae9582abf402ff35bf41dd). - ProTrade Price Formatting Bug Fix: Fix price formatting in ProTrade state hook by using formatUnits instead of parseUnits for limit order prices, ensuring correct decimals (commit 4a8b2381b6374a8d7be18bbfda122f9bb63859f2). Major bugs fixed: - ProTrade price formatting bug: ensured correct decimals by switching to formatUnits in the price calculation (commit 4a8b2381b6374a8d7be18bbfda122f9bb63859f2). Overall impact and accomplishments: - Stabilized deployment pipelines and upgraded runtime tooling across multiple workflows, enabling faster releases with reduced risk. - Consolidated and simplified migration logic, improving data integrity and reducing long-term maintenance costs. - Hardened trading/ordering flows and UI formatting, reducing user-visible errors and improving trust in pricing data. - Demonstrated end-to-end ownership across CI/CD, data migrations, trading SDK, and UI polish. Technologies/skills demonstrated: - CI/CD pipeline management and Node.js version pinning across multiple workflows. - Data migration strategy design and safe rollback considerations. - SDK/trading workflow improvements with schema-aware updates. - UI/UX precision work on number formatting and numeric representations. - Debugging and robust bug-fix discipline in formatting and units.
