Projects

Phase • 2025

Repository Blog Post

A custom interpreted programming language focused on expressiveness and explicitness.

Bridges a semantic gap between dynamic high-level languages and stricter low-level languages.

  • Features clean syntax, static typing, bytecode compilation, comprehensive error reporting, and integrated debugging options.
  • Designed an entirely custom bytecode instruction set and VM for memory safety and portability.
  • Implemented a modular compiler architecture (lexer → parser → type-checker → bytecode generator → VM) enabling easy extensions including new language features, optimizations, and future JIT compilation.

Tech stack: C, CMake

StCats Ops • 2025

Repository

A full-stack internal management platform built for the St. Catherine's British School CS department.

Replaces scattered manual workflows of the department into a single centralized internal system.

  • Features invite-based onboarding, Azure AD SSO, lesson scheduling, a browser-side code editor, and an integrated admin dashboard.
  • Designed a robust backend architecture using Django and PostgreSQL.
  • Commissioned by department stakeholders for real faculty use.

Tech stack: Python, Django, PostgreSQL, HTML/CSS/JS, WhiteNoise, Gunicorn, Azure AD, Render

Void Shell • 2025

Repository

A compact Unix-style shell built from scratch and designed for clarity and extensibility.

Built to understand Unix process orchestration at a deeper level.

  • Features multiprocess command execution, pipeline chaining, output redirection, and builtin debugging tools.
  • Built an intentionally minimal core to align with Unix composition principles and avoid unnecessary builtin complexity.
  • Designed a modular structure for easy extension, including additional builtins.

Tech stack: C, CMake, POSIX APIs

Achievements

  • Three-time 1st Place winner of the Line Robot Competition at StCatsHacks (2023, 2024, 2025) as lead programmer.
  • Completed GCSE Computer Science a year early with a grade 9.

About

I'm interested in systems programming, language design, and backend architecture. I focus on building software that's ambitious, technically rigorous, and practically useful.

Much of my work is self-directed and project-based. I learn best by building systems just above my scope.

I'm working toward larger projects involving distributed systems, applied algorithmic work, and embedded programming.

I intend to study Computer Science in the United States.
