Worked on koreader/koreader, delivering features and fixes that improved device input handling, gesture recognition, and documentation clarity. Enhanced over-the-air update reliability by making update confirmations unmissable and restoring custom exit handling, reducing user confusion. Improved gesture detection across device rotations and stabilized keyboard visibility in input widgets, using Lua for frontend and embedded systems development. Addressed device-specific issues by filtering malformed input events on Kindle and deduplicating power events on Kobo, increasing cross-device reliability. Updated macOS build documentation in Markdown to streamline onboarding. Introduced automatic gesture tap detection on Kindle devices, reducing manual configuration and supporting future hardware changes.
December 2025 monthly summary for koreader/koreader: Delivered Kindle Frame Tap Gesture Autodetection and handling for the gesture_tap input device via FBInk, enabling taps on the Kindle frame to be recognized and acted upon with automatic configuration. This reduces manual setup, improves UX across Kindle devices (PW6, CS), and lays groundwork for seamless support of future devices.

August 2025 (koreader/koreader) — concise monthly summary emphasizing device-specific input reliability improvements and power-management stability. Key improvements delivered: - Kindle: Ignore malformed BTN_TOOL_DOUBLETAP events to improve input handling reliability and gesture recognition on Kindle devices. Commit e1c7445c71d2cf4d62326d471803ed8257fdd019. Major bugs fixed: - Kobo: Deduplicate page turn power events when pageturn_power is enabled by processing only PowerRelease events and swallowing press/repeat, preventing duplicate PowerPress events and unintended power-management behavior. Commit e1b990a4642e182941493433d36e3fa5908ae65e. Overall impact and accomplishments: - Increased user-visible reliability across two popular devices by hardening input event handling and power-management behavior, reducing gesture misdetections and unintended actions. These fixes enhance cross-device consistency and reduce support friction, delivering measurable business value through a smoother user experience. Technologies/skills demonstrated: - Low-level input event handling and device-specific edge-case debugging, cross-platform event filtering, and maintainable change tracing through targeted commits (#13714, #14216).

December 2024 monthly summary for koreader/koreader: Focused on improving macOS build onboarding by simplifying the build documentation. Removed the sentence about adding Homebrew's directory to PATH and relied on the assumption that brew is invokable and PATH is configured, reducing confusion for macOS builders. The update aligns docs with current tooling practices and reduces potential build-time errors and support inquiries without altering the build process. Commit reference used: 85b8689d391bea74a465eef113bab50122a4f5e8 (\"[doc] Update macOS PATH shenanigans (#12873)\").

Month 2024-10 highlights: two pivotal changes in koreader/koreader that enhance OTA reliability and user clarity around OTA updates and exit handling. Implemented Uninterruptible OTA Update Confirmation to ensure final update notices are visible across restarts, reducing user confusion. Fixed regression by restoring the onExit callback in DeviceListener to support custom exit paths (e.g., OTA flows), ensuring proper exit/restart behavior. Overall impact: improved update reliability, reduced user friction during OTA, and stronger stability of exit/restart workflows. Technologies/skills demonstrated: regression analysis, feature delivery with user-facing safeguards, and targeted commit-driven fixes.
