Projects

Backend/Web Development

• Lexiconnect
  • Cloud-hosted web application acting as a compatibility layer and a visualization tool for linguistic analysis file formats such as .flextext and .eaf.
  • Next.JS + Vercel, TypeScript, FastAPI, Python, Neo4j, Google Cloud Platform, Docker.
  • Hosted instances of Lexiconnect's backend via Docker containers hosted within GCP Compute Engine instances.
  • Hosted a Neo4j Instance via a Docker Container with another Compute Engine instance.
  • Implemented Export functionality that interprets the data inside the neo4j database and exports it into a chosen file format.
  • Created Github Action rules that automatically pull changes to the repository on all backend instances and restarts the container.
  • Wrote Cypher queries using the Cypher Python driver in order to retrieve and query data inside the neo4j database.
  • Documented API endpoints and design decisions for easier onboarding of future developers.

• Shadro
  • Shadertoy-like web app wheres users can create and download HLSL shader programs that run directly on the browser.
  • React, TypeScript, Golang, Gin, Postgresql, WebGL, HLSL.
  • Created UI components for users to log in, sign up, or begin creating or modifing shaders.
  • Experimented with a fully custom authentication system, complete with an experimental database from scratch (switched to Postgresql later).
  • Implemented CodeMirror for code entry and modification, as well as a shader preview through WebGL.
  • Wrote 4 HLSL programs (3 for the landing page, 1 for the default shader) for the sake of example and themeing.

Computer Graphics

• Object Renderer
  • Object and material renderer written with C++/OpenGL using realistic Phong or Gouraud Shading.
  • Created an object importer abstraction that produces VBOs and VAOs based on the type of .obj imported (pre-triangulated, n-gons, etc.)
  • Implemented Gouraud and Phong shading, being togglable between the two real-time.
  • Added model transformation features such as scaling, translation, and rotations through an object's model matrix.

• C++ Ray Tracer
  • CPU-based ray tracing renderer featuring glazed surfaces, skybox texture, realistic lighting, and multiple shapes support.
  • Used OpenGL to draw pixels of variable dimensions while CPU program (C++) calculates ray tracing.
  • Included interactive mode, a mode where users can move around the scene in first-person perspective.
  • Added the ability to switch between orthogonal projection and perspective projection real-time at the press of a key.
  • Implemented Blinn-Phong lighting per-ray using the ray's direction and the light's direction, taking into account the object's material properties.
  • Developed recursive ray trace calls for glazed surface implementation.

Other Fun Stuff

• DSTrainer
  a Dark Souls trainer cheat that gives the player control. (C#, WinForms)
• DSRT
  a dynamically-linked library used by DSTrainer to access Dark Souls' memory at run-time. (C++, Win32)
• ShutterBirds
  a Unity game where players take photos to sell them for cool camera, player, and house upgrades. (C#, Unity)
