Founding Software Engineer, Signal Processing + Deep Tech R&D
As the first full-time software engineer at Sonera, I design and program data collection systems and analysis tools, to aid in the R&D process for our novel magnetic field sensor technology. I specialize in digital signal processing and crafting clear and sometimes beautiful data visualizations.
As the first full-time SWE, I build critical hardware test stations and analysis tools that aid the materials scientists and hardware engineers in the R&D process:
•
Designed, built, maintained and upgraded 6 separate automated test stations in the electronics lab, each with accompanying data processing/analysis tools. The materials team operates these user-friendly stations, which constitute the characterization pipeline for all new magnetic sensing samples.
•
Built a library of reusable, performance-optimized components for hardware control, signal processing, and data visualization in Python using the Numpy/Scipy stack.
•
Drafted and enforced company standard software conventions.
•
Set up and maintained company CI/CD.
•
I am well-versed in the power and RF electronics hardware that make up these test stations. I enjoy the hands-on work of wiring, soldering, maintaining and troubleshooting this hardware.
•
Built the first in-house data acquisition program for the integrated sensor prototype, recording magnetic signals via USB.
•
Built real-time signal visualizers (combination of oscilloscope and spectrum analyzer) for two generations of the sensor prototype. These work in tandem with acquisition software and are used both by test engineers in the lab and leadership, in demos shown to investors.
•
Programmed embedded C to improve upon the sensor microcontroller's firmware, and established SOP for embedded development using TI Code Composer Studio.
My primary role was designing/coding an automated procedure in Python to control an electromagnet and take characterization data on our prototype magnetic field sensor. I also assisted with experimental design, CAD for 3D printing, and general lab technician work. I then worked remotely during the school year while completing my EE degree, improving upon the procedure and processing the data it yielded.
My calculus professor recommended me as a tutor for Foothill's Pass the Torch Program, in which students who have excelled in a class provide free tutoring services to other students who request assistance. I enjoy tutoring trigonometry, discrete math, and calculus very much.
Provided in-home therapy services to three young clients on the autism spectrum, teaching and training in basic social and living skills using the psychological principles of applied behavioral analysis (ABA). Recorded quantitative and qualitative data on client behaviors to track client progress toward their goals. Also provided services in a group session setting at the company office in San Bruno.
