Kai Meister - Portfolio

Aloha,
my name is Kai Oliver Meister and I'm a passionate programmer with a Master's degree in Physics. Below this preface you will find a compilation of my past projects, showcasing the wide range of programming languages and frameworks I have worked with. My complete tech stack is listed as toggleable tags in the left sidebar. Clicking on the navbar tabs will lead you to a more condensed overview of my projects, filtered according to the specified fields.

Complete Project Compilation

Fast64 - Banjo-Kazooie Module

●

Directly connect Blender to a Banjo-Kazooie ROM file.

●

Extract level data from the game files, including geometry, textures and gameplay functionalities.

●

Edit existing levels or create new ones, translate them back into N64 data and inject them into the game files.

BerryMe - CNN Berry Recognition

●

Designed and trained a CNN Pipeline to count berries.

●

Pipeline applies various image processing techniques to clean up the data for the CNN model.

●

Determined most problematic aspects of the data by evaluating attention heatmaps.

ASTrAEA Exoplanet Pipeline (M.Sc.)

●

Designed fully autonomous reduction pipeline for astrophysical spectra of exoplanetary atmospheres.

●

Evaluated 1700+ spectra from 20 different exoplanets.

●

Generalized various complex reduction steps with algorithmic approaches to achieve complete autonomy.

●

Devised a module that interfaces into multiple existing APIs to gather and verify data on analyzed exoplanets.

Dusty Lyman-Break Galaxies (B.Sc.)

●

Formulate Dust Models for simulated Lyman-Break galaxies from the Illustris Project.

●

Evaluate models through light-transport code, capture simulated light and identify Lyman-Break features.

●

Compare extracted simulation results with real-world counterparts to assess model accuracies.

Pi-Plays-Pokémon Heatmap

●

Process days of video footage from a Pokémon twitch stream to extract data for statistical analyses (parallelized process).

●

Use OpenCV to match processed footage to map-mosaics to track and export player location.

Bomberman 64 Level Editor

●

Extract level data from Bomberman 64 ROM files and inspect it with multiple responsive viewports.

●

Edit the level data through various GUI tools, translate it into N64 data and re-inject it into the ROM file.

●

Export the level data as .obj for CAD software.

Grady

●

Online grading platform for computer science exams.

●

Student subsmissions are managed in a PostgreSQL DB through Python (Django). Migrated to SurrealDB later on.

●

Migrated Frontend from Vue-2 ➝ Vue-3 ➝ Svelte-4 ➝ Svelte-5 over the course of 2 years.

●

Touched up CI/CD DevOps and automated Testing.

MKDD RNG Bruteforcer

●

Predict random item-draws in Mario Kart: Double Dash!! by simulating its (deterministic) RNG for multiple possible game-states.

●

Given a specific sequence of item-draws, bruteforce for game-states that allow the sequence to occur.

N-Body Brownian Motion Sim

●

Simulate up to 4096 Vicsek swarm particles, utilizing cell-list optimizations to achieve huge boosts in runtime.

●

Extract meaningful data from the simulations and perform statistical analyses on effects like induced phase seperation and clustering.

Copolymer Escape Simulation

●

Simulate diblock copolymers using the MCMC Metropolis algorithm in order to determine escape rates.

●

Utilize Forward-Flux Sampling to boost the statistical efficiency of the simulations.

ScriptHawk - Bomberman 64

●

Monitor and parse in-game memory like player position and movement state in real time.

●

Edit game-state on demand for testing purposes (setting infinite HP, instant warping, editting collectables).

MIPS Assembler

●

Feature-complete MIPS Assembler with additional pseudo-instructions and other QOL implementations.

●

Implements various raw data-types, named constants, labels and a comprehensive branching syntax.

●

Direct, targeted injection of assembled code into ROM files.

Banjo-Kazooie Gap Bruteforcer

●

Analysed game code to understand arithmetic floating-point errors in collision logic, which create infinitesimal gaps.

●

Developed a Bruteforcer to find and exploit these gaps.

MKDD Hex Editor

●

Process large amounts of hexadecimal data in .dtm-format to edit Gamecube TAS movies for further optimization.
