EEL-Drone Project

I developed the core autonomy system for an underwater drone, focusing on sensor fusion, object detection using Ping360 sonar scans, and waypoint generation. I also implemented PID control based on heading to guide the drone’s navigation.

NGCP Weather Station Project

As part of the Ground Control Station team for the Northrop Grumman Collaboration Project, I designed and built an ESP32-based weather station to support environmental monitoring for our search and rescue UAV. I integrated light, temperature, humidity, wind speed, and wind direction sensors to collect and process real-time data. I also created the schematic in KiCad and ordered a custom PCB.

Morse Code Translator

For my Advanced Verilog class, we built a mouse-controlled Morse Code Translator on a Nexys A7-100T FPGA board. The interface included a Morse code reference chart. A short left mouse click entered a dot, while holding the left mouse button for at least 1.2 seconds entered a dash. The translator collected these inputs into a sequence and displayed the corresponding letter when the sequence matched a Morse code character. We could append letters to spell out words, then use a clear button to reset the displayed text when finished.

Disney Imagineer Competition

Participated in a Disney Imagineer Competition. I participated with my friends Joseph Kim and Claire Ku. We designed a company called LAPS. The purpose of the app was to better the structure of the public transport system within LA! We would have various hubs that would connect to a main hub. Shuttles were used to connect these hubs to conduct easier transport within the busy city and reduce traffic. This would lead to less carbon emission within our atmosphere and overall a more happier, public transport efficient city. I was in charge of the 3D model design of the trains and the app configuration, Claire created all the drawings of where our hubs would be and found their proper locations in correlation with an IRL map, and Joe created our project proposal/story.

FPGA Doodle Jump

Leveraging a Digilent Nexys A7-100T FPGA, I implemented the classic Doodle Jump game entirely in Verilog. I designed a VGA controller to generate 640×480 @ 60 Hz timing and double-buffered sprite rendering for the jumper and moving platforms, and built a hardware physics engine to model gravity, jump dynamics, and collision detection. User input is mapped to push-buttons with dead-zone filtering to ensure smooth left/right movement, while a pseudo-random platform generator based on an LFSR keeps gameplay unpredictable. Onboard clock management divides the 100 MHz system clock into a 25 MHz pixel clock for VGA timing and slower clocks for game logic, and I added simple audio feedback via the onboard speaker for scoring events. This project showcases my expertise in synchronous digital design, finite-state machines, timing-critical interfaces, and resource-efficient hardware implementation.

Computer Builds

Here is my personal computer that I built! This is the 3rd computer I’ve built. I have gotten used to the process by now. I’m running a dual boot using GRUB to use Arch Linux and Windows!

Specs: Ryzen 9 7900X, RTX 3070 Suprim, 32GB DDR5 TForce RAM, EVGA 1000W PSU, 1TB M.2. SSD, 8 TB HDD.

I built multiple other PCs as well.

Microcontrollers Stoplight

Using the Microchip PIC18F4620 and MPLAB X IDE, I built a fully autonomous stoplight simulator in C. I mapped the red, yellow, and green LEDs to digital output pins and configured the PIC’s oscillator and configuration bits for an 8 MHz system clock. A hardware timer (Timer0) with interrupt-driven overflow provided precise millisecond timing, driving a finite‐state machine that cycles through red, green, and yellow phases with configurable durations. I also implemented a debounced push-button input for a pedestrian‐crossing request, which temporarily inserted a walk signal into the sequence. Throughout the project, I used MPLAB X’s simulator and on-chip debugger to verify timing, validate state transitions, and optimize code size and performance—demonstrating hands-on expertise in microcontroller configuration, interrupt handling, and embedded systems design.

MagicMirror Smart

I built a fully custom smart mirror using the open-source MagicMirror² framework hosted on GitHub and powered by a Raspberry Pi. On the software side, I cloned the MagicMirror² repo, installed it on Raspbian, and customized modules to display time, weather, calendar events, and headline news. For the hardware, I hand-crafted a wooden frame from raw planks I cut and sanded myself, and fitted a sheet of two-way mirror glass into it. I then stripped down an old monitor to its bare LCD panel and mounted it directly behind the glass, connecting it to the Pi. The result is a seamless, wall-mounted smart mirror that combines embedded Linux, hardware hacking, carpentry, and open-source software customization into a polished, functional installation.

Cat Heart Rate Monitor Harness

Developed a microcontroller-based cat heart-rate monitoring harness using an ESP32, INMP441 MEMS microphone, real-time FFT filtering, and ESP-NOW wireless communication. The receiver unit renders a live ECG-style waveform on a TFT display, enabling continuous, low-power feline vital tracking.

Cafe Sumire Ticketing System

I developed a full-stack ticketing platform for Café Sumire using Node.js on the backend, Docker containers for consistent environments, and Render.com for seamless cloud deployment. The system exposes a RESTful API for creating, updating, and tracking customer tickets, while a responsive HTML/CSS/JavaScript frontend gives café staff an intuitive interface to manage orders in real time. I orchestrated services with Docker Compose, configured network routing and secure HTTPS endpoints, and tuned firewall rules to ensure reliable, secure communication between microservices and the web client. This solution streamlined the café’s order workflow, reduced service bottlenecks, and highlights my expertise in backend and frontend development, containerization, cloud deployment, and network configuration.

AKO by Lee Website

I built AKO by Lee, a responsive website for Lee Calabia’s community-driven beverage and merch brand, using HTML5, CSS3, and vanilla JavaScript. The landing page welcomes visitors with bold imagery and Lee’s signature tagline, then guides them to a menu page showcasing handcrafted drink offerings in a clean, card-based layout. The lounge page creates a virtual gathering space—complete with interactive recipe reveal panels—so fans can explore Lee’s favorite concoctions step by step. Finally, the shopping page presents branded apparel and accessories with hover-activated details and a simple, JavaScript-powered cart for smooth order placement. Built with CSS Grid and Flexbox for flawless cross-device layouts, and enhanced with keyboard-friendly navigation and ARIA attributes, the site reflects Lee’s mission to unite the dance community over great drinks and authentic merch.
