02 · PROJECTS

Featured projects

LLM applications and automation built end to end — from prompt design to statistical validation and deployment.

TradeGuard — AI Governance Platform

GitHub →
StreamlitAnthropic API SQLiteAI Red-Teaming

Working AI-governance platform for firms running AI on trading desks — four modules covering explainability, security, incident response, and vendor risk, grounded in real regulatory research (FINRA, SEC, EU AI Act).

  • Trading-signal audit trail logging plain-English LLM rationales for every BUY/SELL/HOLD
  • Red-team suite firing 10 OWASP-style prompt-injection payloads at a simulated trading copilot
  • Incident tabletop simulator modeled on real cases (Knight Capital, deepfake market panics)

Synthetic Financial Data Generator

GitHub →
PythonOpenAI Time SeriesStatistical Validation

LLM-powered pipeline that generates synthetic log-return time series for financial risk simulations — filling the data gap for rare and extreme market scenarios.

  • Prompt-driven generation workflows for financial time-series data
  • Realism enforced with KS tests, distribution checks, and histograms
  • Automated quality-filtering loop that regenerates failed samples

Multilingual Marketing Text Generator

GitHub →
RAGChromaDB MiniLMStreamlit

GPT-based content system using Retrieval-Augmented Generation to produce context-aware marketing copy across languages and tones.

  • RAG pipeline with ChromaDB + MiniLM embeddings for contextual grounding
  • Prompt templates controlling tone, format, and SEO keywords
  • Interactive Streamlit app with exportable, downloadable outputs

Automated Financial & Operational Reporting

Related experience →
PythonSQL ExcelAutomation

Automated reporting pipelines replacing manual financial and operational processes — improving accuracy, auditability, and turnaround time.

  • Automated extraction, validation, and transformation workflows
  • Cut manual reporting effort by up to 40%
  • Standardized outputs for cross-functional stakeholders

Solar Power Output Optimization

GitHub →
DatabricksPySpark Gradient Boosted TreesBig Data

Machine learning model simulating power output from solar panels, trained on ~700MB of data using distributed computing on Databricks.

  • Trained gradient boosted trees at scale on Databricks
  • Simulated solar power output to support optimization decisions
  • Handled large-scale data processing end to end

Immigration & Inflation in Canada — MPS Capstone

GitHub →
EconometricsXGBoost VARMAX / ARIMAXStatsCan Data

Capstone testing whether immigration drives inflation across Canadian provinces (2010–2025), using a provincial quarterly panel built from Statistics Canada data.

  • Merged CPI, population, immigration, housing, and policy-rate data into one panel dataset
  • Compared linear, regularized, tree-based, and time-series models (ARIMAX, VARMAX)
  • Found interest rates — not immigration — to be the dominant inflation driver (r ≈ 0.7)
