•Eliminated a critical patient-safety defect causing multi-pouch dispensing in ~17% of cycles; collaborated with hardware engineers to diagnose a motor-sync root cause and deployed a software fix that reduced the failure rate to near-zero in field telemetry.
•Revamped the Settings module UI/UX in Jetpack Compose, restructuring navigation architecture and composables to align with evolved product requirements; launched on schedule with zero regression incidents.
•Worked on on-device vision pipelines (heat-seal detection, barcode recognition) under medical-grade accuracy standards, cutting false-negative rates through cross-team refinement.
•Exceeded the team-wide 80% unit test coverage target on the majority of PRs, raising baseline reliability across a safety-critical codebase.
•Streamlined PR reviews by establishing consistent code-review standards and targeted documentation, accelerating onboarding and knowledge transfer for new team members.
•Embedded AI-assisted development tools (GitHub Copilot, Gemini, ChatGPT) into daily engineering workflows; speeding up debugging cycles, strengthening code review quality, and cutting documentation time on a fast-moving codebase.
