Embedded Files
My love for engineering and design is best exemplified by my project and work experience.
Fabricating my projects has developed my design decisions and given me an intuition for how things work. More importantly, it has shown me what does not work.
Gray Water System Automation
Project overview
An ongoing personal project is my gray water system at my parents' home. Water is collected from the washing machine in an initial "dirty" water barrel. A swimming pool sand pump filter is used to clean the clothing lint from the fluid and collected in a "clean" water bin. A mechanical pump then distributes water around the yard through an irrigation drip system.
The manual system was a pain to check water levels and cycle pumps prior to starting a load of laundry so I am working to automate the system. Time-of-flight laser sensors now monitor the water level of the tanks and communicate with an ESP-32 microcontroller to control an LED strip indicating the water level. My next step is to build off the existing code to add control systems to the pumps.
Cal Poly Racing - Formula SAE
Project overview
The Cal Poly Racing team designs, builds, and tests a Formula style car with the goal of competing in a yearly collegiate competition. Our team produces both an internal combustion (IC) and electric vehicle (EV) using the same structural assembly designs with swapped power trains.

Key achievements
My Freshman and Sophomore year was a tough transition time for the team through COVID 19. I worked on the suspension subsystem, making links, mounts, jigs, and constructing assemblies. These formative years introduced me to the team's format, competition rules and regulations, and a grasp of the yearly design cycle.
Junior year I took on the role of Manufacturing lead. In this position, I advised subsystems to ensure the manufacturability of their parts given our facilities and time constraints. I further streamlined manufacturing by creating an inventory database, as well as schedules for critical machining operations. A large part of my role was the transfer of knowledge to newer team members as well as delegating and managing tasks so susbsystems had support accordingly.
Laminar LAA
R&D Intern
Laminar is a medical device company developing an implant to treat patients with atrial fibrillation by eliminating the left atrial appendage (LAA). As an intern, I was exposed to rapid prototyping, testing, and process development.
My primary project was assisting in the development of an automated sand blasting process to condition the inner surface area of catheters. This resulted in a 16 lb. drop in frictional forces between the implant and catheter when actuated.
LiftWalker, Ideomotion LLC.
Project overview
The LiftWalker (patent pending) is intended to aid users with degenerative diseases in transitioning from sitting to standing and provide walking therapy support.
This prototype is made with accessible materials and manufacturing methods, making it affordable and available even in countries with limited resources.
San Francisco Department of Public Works
Project overview
My primary role at SFPW was sizing components for pre-existing fluid-thermal systems. I would model system curves and size pumps and heat exchangers accordingly.
I had the opportunity to work on projects such as new pump stations to accommodate the new Chase Center and the Ocean Beach Wastewater Treatment Plant.
Balance Research - Human Biomechanics Lab
Abstract
Yoga is one of the few activities that directly strengthen muscles involved in balance and coordination. To analyze how postural stability differs between female yoga athletes and a control group for single-leg dynamic movements, balance parameters were exacerbated between participant groups using a fatigue protocol. Participant performed a modified Wingate test procedure on the stationary cycle followed by a transition pose to Warrior III. Of the dependent variables, dominant leg ankle angle, hip moment, GRF, and gastrocnemius activation showed significance. Yoga participants showed less deviation in ankle angle, lower GRF, and larger gastrocnemius activation, reflecting controlled stability. In addition, a larger hip moment was observed, suggesting the desired Warrior III form was achieved.
