I think in systems, dig for root causes, and build for change.
Hard problems are the interesting ones.
Fast is good, correct is better, and trusted is the whole point.
I build things meant to outlast the reason I started them.

Experience

Carnegie Mellon University

Research Contributor

Aug 2026 — Present

  • Conducted LLM privacy research under Prof. Hana Habib, translating research hypotheses into reproducible PyTorch pipelines and implemented DP-SGD fine-tuning for 1–8B parameter models with LoRA and Opacus.
  • Designed and ran controlled experiments across 6 datasets and multiple privacy budgets, evaluating DP vs. non-DP models on training-data extraction and accuracy with confidence intervals.

Experience

IG Wealth Management

Artificial Intelligence Engineer Intern

Toronto, ON · May 2026 — Aug 2026

  • Built a mortgage risk-scoring system from POC to production: deterministic weighted model with external API signals, deployed as a React/Python service on GCP (Pub/Sub, Dataflow, BigQuery, Gemini Enterprise Agents), cutting review time 90% and saving 400–500 underwriter hours/month.
  • Developed a TypeScript MCP connector exposing RocketReach tools to Claude, enabling AI agents to qualify 540+ contacts per mandate and automate an 8-hour manual process.

Experience

Greypoint Industries (YC S26)

Machine Learning Engineer (Contract)

Apr 2026 — May 2026

  • Built the ML tracking system for a $200K Canadian defence proposal, helping drones maintain reliable target tracking when sensors were jammed, spoofed, or unavailable; combined multiple sensor inputs using Kalman filtering and adaptive weighting, reducing tracking error 45%.
  • Built a Python simulation and testing framework that recreated jamming, spoofing, and sensor failures to measure system reliability before deployment, rejecting 99% of spoofed measurements and automatically flagging accuracy and latency regressions.

Experience

Cohere Labs Open Science Community

Research Member · Evaluation

Toronto, ON · Mar 2026 — Present

  • Engineered MAP, a black-box LLM attribution framework classifying 13 frontier model families at 82% accuracy using statistical anomaly detection and feature engineering on model behavior; presented at the Canadian Statistical Student Conference (2026).
  • Built a multi-provider LLM evaluation pipeline in PyTorch with SQLite provenance tracking, 225-feature extraction, and GitHub Actions CI regression tests benchmarking prompt injection and reward model vulnerabilities.

Experience

Arkimetrix Analytics

Data Engineering Intern

Hamilton, ON · Sept 2025 — Dec 2025

  • Architected a containerized document parsing engine via Azure Form Recognizer and Google Gemini API, extracting 10K+ unstructured records and reducing manual processing by 70%+.
  • Orchestrated terabyte-scale backend infrastructure with Apache Airflow, PostgreSQL, and Flask, optimizing database schemas to drive faster end-to-end month-end reporting cycles.

Experience

McMaster University

Machine Learning Researcher

Hamilton, ON · Apr 2025 — Aug 2025

  • Achieved 4x faster pattern recognition on 100GB+ genomic datasets by engineering novel overlapping position algorithms to eliminate sequential bottlenecks in the MAXCOVER protein sequence pipeline.
  • Eliminated reproducibility gaps by building automated testing infrastructure with GitHub Actions, PyTorch, and MLflow; benchmarked latency and throughput across experimental workflows for consistent model validation.

Extracurricular

Google Developer Groups McMaster

Open Source Developer

Sept 2026 — Present

  • Developing Sentinel, an open-source multi-agent LLM security platform using LangGraph, MCP, and RAG to detect software supply-chain, dependency, and CI/CD vulnerabilities in GitHub pull requests.
  • Building an LLM evaluation benchmark of adversarial pull requests (malicious install scripts, unpinned GitHub Actions, secret exposure) to measure agent precision, recall, and false-positive rate.

Extracurricular

DeGroote Finance & Investment Council

Quantitative Strategies

Sept 2026 — Present

  • Developed and backtested algorithmic trading strategies in Python & C# for a ~$180K long-only equities fund; built a multi-asset momentum strategy (RSI, EMA, MACD), ranking top 10 in QuantConnect's open-source competition.
  • Built a statistical arbitrage pairs-trading strategy using cointegration and ADF tests to identify stationary spreads for mean reversion; analyzed risk-adjusted performance using Sharpe ratio, max drawdown, alpha, and beta.

Extracurricular

Mac AI Society

AI Research Project Member

Jun 2026 — Present

  • Building a multimodal deep learning system to classify thoracic abnormalities and estimate severity from chest X-rays, generating saliency heatmaps (Grad-CAM) for explainable localization of model predictions.
  • Developing a vision-language pipeline to produce radiology-style diagnostic reports from imaging features; advancing the project from research to a presented system at the Canadian Undergraduate Conference on AI (CUCAI) 2027.

Extracurricular

DEFEND / 65square

DevOps Engineer

Jan 2026 — Apr 2026

  • Streamlined release automation by engineering CI/CD pipelines with GitLab CI/CD, building and pushing Docker container images to AWS.
  • Standardized dependency management and dev/prod parity by migrating back-end services into isolated Docker containers.
  • Restored platform reliability by leading Level 2 incident response, performing RCA on service failures, and deploying automated pipeline fixes.

MAP

Model-Agnostic Probabilistic Attribution for Prompt Reversal

A statistical framework that identifies which language model produced a given output, classifying source models across 13 model families through black-box probing and probabilistic attribution. 82% attribution accuracy on held-out data with uncertainty estimates, across 10K+ prompts. Presented at the Canadian Statistics Student Conference (Statistical Society of Canada).

Crypto Tick Microstructure

High-Frequency BTC/ETH Lead-Lag Price Discovery

Built a pipeline over 50M BTC/ETH trades from Binance, applying JIT-compiled estimators to correct the sampling bias that distorts correlation at millisecond scale, lifting measured correlation from 0.45 to 0.82. Found BTC leads ETH by 10ms and drives 86% of shared price discovery (t = 7.86); backtesting put the edge's breakeven cost at 0.86bps against 2bps real fees, killing the strategy on economics rather than shipping an overfit backtest.

I'm a Mathematics & Statistics student at McMaster University working where statistics meets machine learning. Right now I'm researching LLM privacy at Carnegie Mellon and model evaluation with Cohere Labs; before that I took AI systems from prototype to production at IG Wealth Management. Away from the terminal I am passionate about quant finance (34th in Citadel's Australian Trading Invitational), chess, basketball, the gym, cars and video games.
