PROFESSIONAL EXPERIENCE

Spryte Medical Sudbury, MA

Software Test Engineer October 2023 — April 2025

Trained AI to ensure accuracy in annotating neuro-vascular medical images: collaborated with engineers to optimize the AI chain, improving performance and reducing annotation time for aneurysm detection by physicians.

Executed timely merge request testing to support the on-time deployment of new features and critical bug fixes and owned the SDLC QA side, as part of the shift left initiative.

Partnered with the Probe R&D team during the early development phases to test devices, investigate probe-related issues, and guide software usage.

Developed representative testing environments and procedures for optimal analyzing of neuro- medical image streams collected through physician-operated probes.

Created, executed, and maintained comprehensive test protocols for software verification and validation (V&V) in a regulated medical device setting.

Identified and documented over 77+ software bugs and behavioral anomalies, improving software stability and reducing developer resolution time.

Refined and updated 20+ test protocols in collaboration with QA and R&D, improving clarity, consistency, and effectiveness across testing documentation.

Conducted detailed ad hoc and regression testing, discovering numerous early-stage issues in new features and undefined behaviors.

Delivered comprehensive investigational reports to software engineers, facilitating deeper debugging and enhancing annotation system reliability.

Independently conducted monthly Jira NPS validations and supported dry runs of testing protocols for upcoming software releases.
