GPS PCB Design Verification

Led design verification for a satellite GPS PCB, shaving 4 weeks off testing by soldering a PCB, analyzing power regulation and latch behavior via LTspice, and verifying physical assembly using DMMs, oscilloscope, power supplies, and electronic loads.

Test Rig Interface PCB

Designed, ordered, assembled, and validated an interface board bridging a flight PCB to an automated test rig, enabling integrated and automated testing. Underwent full product lifecycle including design reviews to meet customer needs, parts sourcing with efficient costs, and in-house assembly and validation.

Discrete LDO Test PCB

Developed and utilized a test PCB to analyze a discrete LDO designed for long-term radiation and thermal cycling, uncovering stability issues and preventing costly redesign through Bode instrument analysis, thermal analysis, and LTspice simulations.

Pulse-Driver PCB

Designed a low-side NMOS pulse driver PCB that streamlined board power supply testing and step response analysis.

ADC Firmware

Wrote firmware in Arduino to validate an onboard ADC, implementing SPI communication and data readout from flight channels to aid in board-level bring-up and testing.

Assembler, Linker, and Machine Code Execution Simulator

Completed a series of projects that assembles individual assembly-language files (RISC-based architecture) into object files, links the object files to produce a single executable, and simulates the execution of the machine code.

Pipelined Datapath Simulator

Produced a program that simulates every cycle of a 5-stage pipelined processor with detect-and-stall, data forwarding, and predict branch-not-taken strategies. Simulator written in C, test cases written in RISC-based assembly language.

Cache Simulator

Added cache-access functionality to machine code execution simulator, acting as a write-back, allocate-on-write cache of tunable associativity. Simulator functions written in C, test cases written in RISC-based assembly language.

Euchre Cardgame Simulator

Built a C++ simulation of the card game Euchre featuring human and bot players, using object-oriented programming with inheritance and polymorphism to model cards, players, and gameplay logic.

Machine Learning Post Classifier

Implemented a C++ machine learning classifier that automatically labels Piazza posts by topic using a bag-of-words model and probabilistic learning techniques, gaining experience with containers like sets and maps for natural language processing.

Content-Aware Image Resizer

Created a content-aware image resizing tool using seam-carving to remove low-energy pixel seams, with extensive testing and debugging of pointers, streams, and abstract data types.

Automated Plant Keeper with Computer Vision A.I.

07/24 to 08/24

Created a system to automatically provide water and light to a plant with machine-learning image recognition to adjust moisture and light-hour thresholds. Used an ESP32 with firmware in Arduino to measure soil moisture and light, control a water pump, and take pictures with a camera and send to a Flask server hosted by my laptop. Created a Flask server to send the image to a Colab script that uses a YOLO model to detect leaves, then a convolutional neural network for each leaf to determine if the plant required more frequent watering and light.

Optics Research for Quantum Key Distribution

03/25 to 04/25

Explored the principles of Quantum Key Distribution and the physics of light and photonic qubits traversing the atmosphere from satellites to ground stations. Researched various aproaches for encoding quantum information into photons, multiplexing for optical communication, and adaptive optics for satellite-to-ground transmission. Proposed combined time- and polarization-division multiplexing with time-bin quantum encoding to minimize atmospheric effects.

Quantum Circuit Simulator (QuaCS)

03/25 to current

Creating a simulator for basic 6-qubit quantum circuits with an interactive circuit-building tool, results for probability and randomized measurements, and support for entangled quantum states. Using Typescript for the back-end and React.js for the front-end. I'm working on this with a friend, and support for front-end features and entanglement is in progress!
