Python, PyTorch, HuggingFace, Opacus, LoRA • CS4413 Foundations of Privacy

• Cleaned customer-support text data and added fake sensitive “canary” records to test for leaks, then trained five GPT-2 models, each with a different privacy setting.
• Measured how much of the fake sensitive data each model leaked back out: the most private model leaked 0%, versus 95% for a standard model.

Python, Flask, Scikit-learn, Pandas • GitHub

• Processed and converted 11,000+ text messages into numeric features (TF-IDF), then trained and compared several models to find the most accurate one for spotting spam.
• Reached a perfect F1-score of 1.00 on test data, and set up automatic retraining once enough new messages are labelled through the app.

Python, FastAPI, Claude API, PostgreSQL, Docker, Google Cloud Run, Vercel, Chart.js • GitHub • Live Demo

• Connected the Claude API to automatically read each submitted issue, sort it into the right category, and remove the need for manual triage.
• Containerized and deployed the backend to Google Cloud Run and the frontend to Vercel, storing results in PostgreSQL with a Chart.js dashboard for operational insights.

Fredericton, NB

• Prepare and issue accurate freight spot quotes each day by researching current rate data and shipment details, prioritizing urgent requests in a fast-paced office environment.
• Resolve incoming pricing and shipment tickets by coordinating with carriers and tracking data across the shipment lifecycle, keeping records accurate for logistics reporting.

Fredericton, NB

• Promoted to team manager for clear communication and problem-solving; resolved 90% of 5–10 daily escalations on first contact by analyzing recurring patterns across 1,000+ telecom records.
• Coached four agents on escalation protocols and supported 20+ daily customer inquiries across multiple carriers.

Next.js, TypeScript, PostgreSQL, Prisma ORM • krishivet.ca

• Modelled an 8-entity PostgreSQL schema and built a custom admin dashboard on top of it, then deployed and continue to maintain the live production site.

Next.js, TypeScript, PostgreSQL • roboflight.vercel.app

• Migrated a legacy PHP/WordPress codebase to a modern Next.js architecture, rebuilding the site's structure and documenting the new system for future maintainers.
