πŸ‘‹ About Me

I am a Computer Science (BCS) and Business Administration (BBA) double degree student at the University of Waterloo and Wilfrid Laurier University. I build production-grade data pipelines, fine-tune large language models, and ship full-stack financial and developer tools end to end β€” from model training to deployment.

  • πŸ”­ Currently building: AI agents, LLM fine-tuning pipelines, and quantitative trading tools.
  • 🌱 Currently learning: distributed training, retrieval-augmented generation, and low-level performance optimization.
  • πŸ” Currently seeking: SWE / ML Engineer Co-op opportunities for Fall 2026.
  • ⚑ Fun Fact: I fine-tuned a 6.7B parameter LLM on my laptop and Kaggle just to solve LeetCode problems faster.

πŸš€ Featured Projects

πŸ”€ Tokenmaxxing

  • Agentic Handoff Portal: macOS desktop + CLI bridge that lets you plan on ChatGPT Web and execute with a local CLI agent (Codex, Claude Code, Antigravity).
  • MCP over the Wire: Exposes a local Model Context Protocol server securely over Tailscale Funnel so remote chat sessions can drive on-device tooling.
  • Token Efficiency: Offloads heavy planning to the browser frontend, reserving local agent context for execution.

  • Performance Leap: Fine-tuned DeepSeek-Coder 6.7B on 2,400 curated problems via QLoRA.
  • Result-Oriented: Achieved a +42% accuracy boost overall and +214% on hard problems through domain-specific data curation.
  • Local Deployment: Built an evaluation harness with sandboxed execution, merged LoRA adapters, and exported to GGUF for local Ollama inference.

  • TUI Dashboard: Built a terminal interface orchestrating local AI agents for automated PR code reviews.
  • Non-Blocking UI: Used asyncio workers so the interface stays responsive during long AI review cycles.
  • Security First: Integrated native gh CLI auth (no raw API keys stored) and staged reviews locally so comments are never posted without explicit confirmation.

πŸ“ˆ Alpha Radar

  • Real-time Scanning: Vectorized pandas engine detecting institutional support levels (FVGs, equal highs/lows) across 500+ tickers.
  • Backtesting Engine: Custom simulator evaluating 700+ historical setups across NVDA, GOOGL, and AAPL, hitting a simulated 74% win rate.
  • Dynamic Visuals: Deployed with WebSocket data streams rendering interactive TradingView charts.

  • Multi-Model Pipeline: Gemini-to-Gemini workflow where the first model digests macroeconomic context and the second runs portfolio analysis.
  • Calendar Integration: Auto-syncs market events (FOMC, CPI, NFP) and earnings schedules for 30+ megacap equities.
  • Reliability: Built a 2-key rotation system with model fallback, reducing failed request rates by 90%.

πŸ“± IntelliCal

  • AI Nutrition: Gemini vision pipeline parsing meal photos into structured JSON with ~88% accuracy and zero parsing crashes.
  • Gamified Retention: Forest gamification system syncing real-time user progress to Supabase/PostgreSQL.

πŸ’Ό Professional Experience

🚘 Software Engineer @ AutoTrader

Toronto, ON (Hybrid) β€” Sept 2025 – Dec 2025 Β· Jan 2025 – Apr 2025

  • Data Scale: Scaled AWS Python pipelines to crawl 500K+ URLs, cutting runtime from hours to minutes via parallel workers + Redis caching.
  • Stakeholder Analytics: Built weekly ETL into PostgreSQL and Tableau dashboards used by 20+ leadership and marketing stakeholders.
  • ML Modeling: Built a scikit-learn scoring engine ranking 20K+ articles to prioritize content strategy.

🎟️ Software Engineer @ HeadsUp Group & iVirtual

Toronto, ON β€” Jan 2024 – Apr 2024

  • Database Consolidation: Dockerized AWS ETL pipelines merging 4 siloed databases, saving 300+ engineering hours/year.
  • Notification Engine: Built a SendGrid pipeline with queued retries for an NHL Kraken rewards pilot, sustaining 80%+ weekly engagement.
  • User Segmentation: Built a pipeline clustering 100+ user profiles by behavior for personalized rewards delivery.
