Projects

Tokenmaxxing

A desktop GUI and local MCP server for token-limit arbitrage: maximize the context window on flat-rate web models, generate a detailed implementation plan, then hand it to local CLI agents for cheaper execution.

ResultIncreases effective usable tokens by up to 2× by offloading context-heavy planning to flat-rate web models.

Agentic GitHub PR Reviewer

Native desktop GUI, terminal TUI, CLI, and MCP server for reviewing GitHub pull requests with local AI agents, all wrapped as subprocesses so raw API keys stay out of the workflow.

ResultRuns parallel agent reviews and synthesizes one consensus report before anything is posted.

DeepSeek LeetCode Fine-Tuning

Fine-tuned DeepSeek-Coder 6.7B on 2,400 curated LeetCode problems with 4-bit QLoRA, then built a sandboxed evaluation harness and exported merged adapters for local Ollama deployment.

ResultImproved solve accuracy 42% over base, including a 214% gain on hard problems.

About

Who I am

I'm a computer science and business double-degree student at the University of Waterloo and Wilfrid Laurier University. I build applied AI platforms, agentic workflows, and machine learning systems that run at scale.

I've completed three software engineering internships, including two terms at AutoTrader and one at HeadsUp Group, shipping large-scale AWS data pipelines (crawling 500k+ URLs), Tableau metrics dashboards, and containerized ETL services.

On my own time, I build and publish advanced projects, from orchestrating parallel multi-agent reviews via FastMCP servers to fine-tuning LLMs using QLoRA and constructing 3D point cloud digital twins.

Outside of work I sharpen my problem-solving with LeetCode, and for fun, I've shipped a Granblue Fantasy Relink mod with 29k downloads and 610 endorsements on Nexus Mods.
