About me
I'm a software developer with A-Levels in Further Maths, Maths, and Computer Science A-levels. Based in Harpenden, I'm interested in building things from first principles: ranging from raycasting engines to ML game AI or financial models.
In the future I'm aiming for a career in quantitative finance as it coalesces mathematics, probability, and computation. If you're hiring interns, running programmes, or just want to talk maths and code, I'd love to hear from you.
Projects
Raycaster Game
Rebuilt the Raycasting engine that I originally created for my EPQ, and then extended it. Moved ray calculations into an OpenGL fragment shader, and implemented wall and floor textures. Then, I added sprites and created zombies to run away from.
Raycasting Engine
Built a 2D raycasting renderer from scratch, implementing Digital Differential Analysis to bypass vector dot products to compute wall intersections and perpendicular distances.
Procedurally-Generated Platformer with AI Boss
Designed a 2D platformer with a reactive enemy using reinforcement-learning-inspired exploration/exploitation. Levels generated via Perlin noise, then layered with recursive generation to produce natural, playable layouts.
Bigram Language Model
Developed a Markov-chain bigram model for text generation at GFF AI Summer School. Analysed the performance limits of probabilistic language models at scale — understanding where statistics meets intelligence.
Student-Focused GPT Wrapper
Built a lightweight AI tool providing exam-board-specific responses. Designed prompt structure and memory constraints to explore how model context affects output quality — prompting as an engineering problem.
Arithmetic Logic Unit
Designed and built a fully functional ALU with accumulator inside Minecraft using logic gates — a ground-up digital logic exercise that makes computer architecture tangible.
Artist Portfolio & E-commerce Site
I fully designed and deployed a public website for an artist to showcase and sell work. I translated business requirements into a technical solution, working directly with the client from brief to launch. Check it out at hdcarew.com
