Electromechanical Subsystem Technical Lead (Next‑Gen Architecture) - DEXCOM
Led system‑level development of a critical electromechanical sensor‑connect subsystem for a new electronics architecture, spanning architecture definition, build readiness, validation planning, and cross‑functional execution.
What I did:
Owned electromechanical interface execution and integration readiness
Stabilized and transferred a sensitive manufacturing process to enable scalable builds.
Coordinated firmware integration under cybersecurity/data constraints for end‑to‑end demonstrations.

Risk‑Based Test Platforms & Automated Validation Systems (HW + SW + UI) - DEXCOM
Led system‑level test strategy by translating requirements and failure modes into targeted test methods and decision‑ready evidence for stakeholders for a high priority projects. Built system‑level automated test architectures and real‑time data acquisition/diagnostic pipelines supporting feasibility through V&V and clinical readiness, including automated benchtop test systems and tooling.
What I did
Developed system-level automated test architectures (LabVIEW/MATLAB/Python) and diagnostic pipelines.
Designed benchtop electromechanical systems enabling repeatable experimentation and validation.
Led mechanical test efforts and technician training in a structured workstream.

Wear Duration Extension: 10 → 15 Days (Reliability Program) - DEXCOM
Led cross‑functional test execution across bench, preclinical, and clinical studies to support extension of wearable patch wear duration from 10 to 15 days through data‑driven reliability characterization.
What I did
Led test leadership for evaluating patch on bench as well as on humans
Designed and drove clinical studies for patch reliability and safety evaluation
Derisked the 15 day patch, in order to move towards product development phase
The selected patch became one of the top technologies responsible for 15 day wear period in the product
