H2X Engineering is a web-based application that replaces tedious pen and paper calculations done by civil engineers worldwide.
It allows designers to draw, iterate, and experiment with entire building designs easily on top of architectural plans. It is very user-friendly and allows live documents via web sockets and operation transforms.
It successfully calculates arbitrary systems with graph algorithms and novel techniques that I designed for this specific task.
Front end: Vue.js, WebGL, WebSockets
Back end: Express.js, NginX, typeORM, PostgreSQL, Ubuntu.
I built and designed the full stack - all technical aspects of the project, with the client's direction and product guidance. I led a small team of junior to mid-level developers on onboarding and development at the later stages of the project.

A web app that displays data visualizations about manufacturing artifacts during the additive manufacturing process in a user-friendly way. The web app also takes care of administrative tasks and manages assets like raw materials and their usage.

Liasoned with analytics developers to integrate their data into the web app and worked directly with the CEO to identify needs and design UI stories and solutions to meet those needs.

A toy personal project.

A minesweeper game written in Java showcases a few different AI algorithms that solve the game.

1. Simple AI can solve some beginner games.
2. Backtracking algorithm will solve most expert games to the best ability until it gets stuck due to exponential in time complexity.
3. Frontier DP will sweep the boundaries piece by piece, unlike backtracking, which permutates an entire boundary at once. It can solve pretty much any sized game in practice, despite Minesweeper being NP-complete in theory!

A personal project of mine.

Using an arbitrary precision library (MPIR) I created a Mandelbrot Set viewer with infinite zoom.
It is a multithreaded C++ application with a shared scheduling stack.
An important optimization was to use divide and conquer and some heuristics to color in solid blocks and avoid lots of unnecessary pixel calculations.

CUDA support and perturbation optimization are coming up next!

At the university, I designed and developed the software for:

(1) A robot maze-solving and object collection
The robot identifies and locates a list of objects before exiting a random maze
- Light and distance camera integration used for object recognition
- SLAM (simultaneous location and mapping) algorithms
- OpenCV for blob detection
- Pathfinding algorithm using state-exploded A*, encoding the orientation of the bot as well as its position to find the optimal path.

(2) Tic Tac Toe robot arm
The robot arm plays tic tac toe against a human opponent using colored blocks that it picks up.
- OpenCV for block recognition
- Operation with the Sebastian robot arm
