WorBots App

A full-stack scouting and team management tool for The WorBots, an FRC robotics team I was on from 2022-2025. It handles collection and analysis of scouting data from other teams at competitions, attendance tracking of students, and team event scheduling.

Features:

• A live scouting form that lets team members press buttons to track robot's actions in real time
• Scouting assignment system where members can claim teams in each robotics match to watch, ensuring perfect team utilization
• Analysis and comparison of stats, including time-based analysis, point value calculations, and graphs of attributes over time
• User account creation and management, along with categories for different permissions and roles on the team
• Creation of events and attendance tracking for members at those events
• Todo lists for managing some complex tasks and packing reminders

Specifications:

• Built using the Rust programming language and the Rocket web server framework
• No frontend frameworks were used, only static templates and pure JavaScript in order to reduce load times for team members at competitions
• Hosted on Heroku Dynos, including a PostgreSQL database
• Hand-rolled authentication system, including hashing and salting of passwords
• User interface and elements were designed from scratch, and made to look good on mobile as well as desktop
• Constantly got feedback from other team members and leads in order to improve the user experience

Nitrolaunch

A "launcher" for the game Minecraft, which handles installing different versions of the game, authenticating the user, and managing custom content. A passion project built over three years and thousands of hours.

Features:

• Installation of isolated versions of the game, called "instances"
• A fully-featured plugin system which allows users to extend the application with new features
• Microsoft OAuth authentication, including secure storage of credentials
• Users can browse custom content for the game from multiple different websites, and install them automatically
• A community project with over 75 stars on GitHub

Specifications:

• Includes both graphical and headless CLI interfaces, built using Rust and the Tauri app framework
• Installation of the game involves:
  • Reading and writing configuration
  • Asynchronous file and network IO operations
  • Reverse-engineering multiple APIs
• Fully custom plugin system uses JSON over stdio streams to allow modification of functionality using any language
• A custom domain-specific language that allows for more complex content packaging, with lexer, parser, and evaluator built from scratch
• Dependency resolution system that installs required packages, figures out optimal package versions, and rejects conflicts
• User interface was designed from scratch along with input from a designer on another project
• CI build system which packages the launcher and plugins for different platforms

FIRST Robotics

The FIRST Robotics Competition (FRC) is a four-year high school program where schools build robots in 6-8 weeks to compete in challenges against other robots. I was the student lead of our program's software team for two years.

Software Highlights:

• Followed the design process to architect subsystems and software designs in order to solve problems
• Wrote robot code in Java which would read and analyze high-frequency sensor data hundreds of times per second
• Similarly, created and tuned complex feedback and feedforward control loops and structures to command robot mechanisms
• Designed automated features such as fully independent robot operation with trajectory planning and features to assist robot drivers
• Used Python and OpenCV along with pose solving algorithms to estimate the robot's position on the field in real time
• Used live and after-match telemetry data to improve robot performance

Hardware Highlights:

• Solved electrical issues such as current draw imbalances, short circuits, and connection problems
• Created a closed internal network on the robot along with a Raspberry Pi coprocessor to run computer vision systems
• Researched and maintained cameras to aid with computer vision
• Managed firmware versions of hardware products on the robot

Communication Highlights:

• As a software subteam lead, spent time orchestrating others to complete tasks, teaching programming skills to new members, and keeping track of deadlines
• Collaborated with other team members to reach goals
• Worked under tight time constraints in a fast-paced environment, where issues with the robot would often need to be fixed in mere minutes.
• Gained valuable speaking skills talking with judges about the robot and rehearsing a six-minute judged presentation about our team along with two others. Our presentation team won an award for the best performance among fifty other teams.
