Sterlu worked extensively on the defisaver-positions-sdk repository, delivering features and fixes that improved DeFi protocol integrations, data reliability, and release management. Over ten months, he enhanced Aave V3 and Summer Vaults support, modernized blockchain interactions using TypeScript and the viem library, and consolidated staking APY logic for maintainability. His work included refining error handling, updating test suites to match live market conditions, and integrating Merkle rewards for accurate yield reporting. By focusing on code hygiene, semantic versioning, and robust backend development, Sterlu ensured the SDK remained reliable, maintainable, and ready for downstream consumption by partners and users.
For 2026-03, delivered Summer Vaults data fetching enhancements and a Positions SDK upgrade (to 2.1.73) enabling support for new vault types; added deployment tracking blocks and updated Summer Arbi USDC vault addresses, plus a naming simplification removing the 'Lower Risk' designation. These changes improve data coverage, deployment accuracy, and product clarity, while aligning with the 2.1.73 release to ensure compatibility across the SDK surface.

February 2025: Delivered key reliability and maintainability improvements across defisaver-positions-sdk and defisaver-sdk. Major accomplishments include consolidating staking APY calculations into getStakingApy, enhancing APY API error handling with safe defaults and tests, and fixing a division-by-zero edge case in Liquity V2 position calculations. Stabilized CI by addressing an external nock flake (commenting out a failing test). Per-release housekeeping included SDK version bumps to 0.0.211 (positions SDK) and 1.2.20 (core SDK). Note: mid-month a rollback removed the robust APY error handling enhancements and the staking utilities test file as part of stabilization. Overall impact: higher data reliability, reduced duplication, and a more maintainable, predictable release cycle that supports safer onboarding of users and partners.

Month: 2024-12 for defisaver-positions-sdk. Focused on maintainability, reliability, and release discipline. Key features delivered include documentation improvements for MorphoBlueHelpers (JSDoc and comments) to clarify parameters for liquidity reallocation and borrowing-related helpers, and routine release maintenance updating versions to 0.0.186 and 0.0.195. Major bugs fixed include correcting the detection of GHO as a native asset in Aave V3 market data by using market.value (not market.shortLabel), ensuring accurate asset identification. Overall impact: improved code readability, more reliable market data handling, and smoother downstream integrations due to precise versioning. Technologies/skills demonstrated include JavaScript/TypeScript documentation standards (JSDoc), code hygiene, debugging of DeFi market data conditions, and release management with semantic versioning.
