Projects
Cover Voice
A reusable cover-letter template system with a custom template engine, self-hosted on a managed VPS and accessible at cover-voice.dev. Built to make writing cover letters easier.
- Single pass parser with contextual errors and usage tracking of entity relations.
- OpenAPI compatible type safe REST API for secure frontend/backend communication.
- Server side PDF generation, replacing blocks and variables with custom
{{ variable }}and{% block %}syntax. - Directed and reviewed AI-assisted implementation work.
Crux Lang
A gradually typed, embeddable, memory managed, interpreted programming language based on Lox from Crafting Interpreters. This project has strengthened my understanding of programming language design and implementation as well as key factors of performance and optimization.
Some features of the language include:
- Gradual typing with a stack based type system in a single pass compiler.
- Pooled object management for 36% faster complete program execution in memory intensive applications.
- Slab allocators for efficient memory allocation and deallocation, reducing system call overhead.
- Object Oriented Programming with the use of structs and struct composition.
- Module system with
pubkeyword for public identifiers that other modules canuse. Result[T, E]type for error handling, andmatchexpressions for pattern matching.- Embedding interface based on Wren's embedding API.
Beach Defenders
A pirate themed 3D tower defence game built with the Unity Engine. This game features procedurally generated levels with hordes of undead enemies threatening your beach. You are equipped with a sword and a revolver to take down the undead horde and protect your beach.
Flora Engine
A 2D UI rendering engine built on SDL3, focused on layout and event handling, providing a foundation for creating performant Graphical User Interfaces in C.
