Oct 1, 2025October 2025: Delivered a new API enhancement for Opentrons/opentrons by adding an explicit tips selection order to Liquid Class Transfer. The new 'tips' argument enables precise selection and ordering of tips, improving accuracy and predictability in multi-channel liquid handling workflows. Implemented as part of PR #19879 with commit b143a32f07fffa63fb6f54e190abba85d4f64061. No major bugs fixed this month; stability improvements accompany the feature. Business impact: higher reliability and reproducibility in automated protocols, enabling faster experiments and smoother automation integration. Skills demonstrated: API design, Python development, version-control discipline, and cross-team collaboration.

Mar 1, 2025March 2025 monthly summary for Opentrons/opentrons: delivered key liquid-handling enhancements in core API and expanded multi-channel capabilities, with a focus on reliability, maintainability, and throughput. Implemented a core refactor to consolidate duplicate logic in instrument context liquid transfer functions, improved volume handling with constrained splitting for large transfers, and enhanced error messaging for liquid class retrieval to reduce operator friction and downtime. Added multi-channel (multi-tip) support with well grouping and nozzle-map targeting for 96/384-well plates to boost precision and efficiency. Fixed descriptive errors for OT-2 Liquid Classes usage to increase system robustness. These efforts strengthen the API surface, improve testability, and enable safer, higher-throughput experiments.

Jan 1, 2025January 2025 monthly summary for Opentrons/opentrons: Delivered two high-impact API and core-liquid-handling enhancements that improve safety, accuracy, and automation reliability. Key outcomes include: (1) Protocol API safety and touch_tip accuracy improvements, combining commits that prevent mistyped liquid-class property settings, wire up mmToEdge to liquid class transfer, and validate touch_tip with edge offset and radius; and (2) a new InstrumentContext.consolidate_liquid() API to merge liquids from multiple source wells into a single destination with robust validation and delegation to the engine core logic. These changes collectively reduce protocol errors, enhance measurement fidelity, and enable more flexible liquid handling across wells.
