March 2023 → Current

Led international military product certification strategy across multiple jurisdictions (US, India, Sweden, Italy), enabling defense market access and entry
Supported European market capture through submittal of Conformity of Production certification, aligning ATI products with EU quality standards and legislation
Influenced management to invest in $100K internal electromagnetic compliance testing capability, reducing regulatory risk and cutting external lab outsourcing costs by roughly $20K to $40K across various product design iterations
Translated complex technical and regulatory requirements into executive briefings to drive strategic resource decisions on the Next Gen Transmission Controller
Developed statements of work, scope documents, and test plans for the US, Italian, and Indian governments

North American Lighting

March 2021 → March 2023

Aligned engineering, sales, and procurement teams to translate customer requirements into product specifications, including RoHS compliance, cybersecurity, and passenger vehicle safety requirements such as light intensity and signal timing
Designed a microcontroller-based circuit using CAN/LIN to interface with secondary PCBs and the body control module
Analyzed market trends to inform pricing strategy and high-value supplier negotiations
Mitigated supply chain risk through strategic sourcing, achieving $1.2M in cost avoidance
Used MathCAD to calculate worst-case circuit analysis (WCCA) failure modes across varying environmental conditions

Purdue University

Aug 2020 → Mar 2021

Worked with LYOHUB to analyze the effects of the lyophilization process through RF-powered sensors
Used lab equipment including digital multimeters, oscilloscopes, and signal generators to debug sensors in the frequency and time domain
Soldered SMD components and used Altium Designer to lay out PCBs
Analyzed and presented data using MATLAB
Proposed an efficient charging process for the IndyGo bus system based on multivariable data spanning state of charge, battery state of health, and route pattern
Built a PID algorithm in MATLAB/Simulink to control motor efficiency across a varying input range

North American Lighting (Freelance)

Nov 2019 → Feb 2020

Designed and implemented a microcontroller-directed holiday sleigh (Arduino) in C, using arrays, pointers, and other core programming techniques
Designed a protection circuit for sensitive headlights and tail lights using opto-isolators and other components to negate transient voltage spikes
