Medical device software with dual functionality as an Anesthesia Workstation and Ventilator. The system calculates anesthetic agent dosage based on patient parameters like ideal body weight and age. It controls a heated vaporizer that converts liquid anesthetic into vapor for patient inhalation, and post-surgery transitions to ventilator mode to deliver O2, monitor inhaled O2 and exhaled CO2, and trigger critical alarms. Also part of the AI team in VMC, fine-tuning LLM prompts to auto-generate BDD feature files and Python automation scripts. • Developed and executed automated test scripts in Python using Squish IDE and BDD framework to validate anesthesia and ventilator workflows. • Designed reusable APIs and test objects to support functional and regression testing of medical device software. • Collaborated with AI team in VMC to fine-tune LLM prompts for automated generation of BDD feature files and Python automation scripts. • Identified errors and reliability issues, driving root cause analysis to prevent future occurrences. • Participated in Agile Scrum ceremonies including sprint planning, daily standups, sprint reviews, and retrospectives. • Coordinated with release/dev teams during deployment calls to verify build stability and post-release functionality.
