Projects annotated with [C] are software projects, [T] are tutoring projects, and [P] are unpublished or unpresented research projects.

Symbolang | [C] github.com/zrygan/symbolang

Implemented a parser, lexer, and interpreter for a simple programming language using emojis in Go.

Raytracer-Rust | [C] github.com/zrygan/Raytracer

Developed a Python-based project exploring core concepts in two-dimensional ray tracing algorithms, featuring support for simple emitters and absorbers.

Implemented geometric and numerical algorithms—including parametric equations, linear spaces, and trigonometric calculations—to simulate light-object interactions and spatial behavior accurately.

Rewrote and optimized the project in Rust to improve low-level performance, with emphasis on memory management and lifetime handling, achieving 12 times performance improvement over Raytracer-Python.

Filipino Language Case Study | [P] github.com/zrygan/Filipino-Case-Study and [C] github.com/zrygan/LanguageTool-Case-Study

Co-authored a case study on common Filipino and Bikol language grammar and style mistakes, proposing automated solutions using finite-state automata.

The project also analyzed Filipino grammar rules that are difficult or impossible to model using regular languages, highlighting limitations in formal language theory.

Nachos, Chips, & Dips: Crunching Cryptos, Algos, and Symbols | [T]

Planned and hosted a lecture series highlighting real-world applications of Theoretical Computer Science concepts from the Software Technology program. The event featured:
Jonathan Mantura (faculty) on cryptography in data security
Ross Tan (tutor) on regular expressions for email validation and password strength
Myself on tries and string searching algorithms

Led event logistics, coordinated with speakers, and delivered a technical lecture to fellow students.

Food Map | [P,C] github.com/zrygan/Food-Map

Led the design and development of a Python-based project exploring concepts in informed (A, UCS) and uninformed (DFS) graph search algorithms, integrating both a priori and a posteriori analysis.

Collaborated with three otherpeople, serving as the lead programmer and primary researcher.

Presented findings on trade-offs between preprocessing and query-time performance

Traditional and Modernized Jeepneys: An Assessment on Comfort, Ease of Use, and Safety | [P] AnimoRepository.

Authored and presented a conference paper at the 5th DLSU SHS Research Congress, in collaboration with Micah Cabatingan, Margarita Ko, and Diego Manalo, under the guidance of Dr. Neil Lopez and Dr. Jose Biona from the Gokongwei College of Engineering at DLSU.

Designed and executed a mixed-methods study involving 30 participants to assess perceived comfort and safety through heart rate data and fluctuations.

Applied thematic coding, developed data visualizations, and calculated measures of central tendency for analysis.
