Applied machine learning and research engineering. Master of Engineering student in Electrical & Computer Engineering at the University of Toronto, graduating April 2027.
Currently building two systems: a conversational agent that assesses code understanding from a student's own submissions, and a retrieval layer for clinical scale extraction that answers only where the transcript carries evidence and abstains otherwise. Alongside those, engineering education research at ISTEP.
Open to full-time roles from May 2027 in applied machine learning, research engineering, and software and data engineering.
Machine learning: PyTorch, Hugging Face Transformers, PEFT and LoRA fine-tuning, scikit-learn, statsmodels, ONNX Runtime and INT8 quantization, sentence-transformer embeddings
Retrieval and LLM systems: LangChain, ChromaDB, retrieval-augmented generation, semantic search, prompt engineering, BERTopic, spaCy, TF-IDF
Evaluation: RAGAS faithfulness and context-recall scoring, prompt-order bias testing, calibration and abstention, failure-mode diagnosis, LangSmith tracing, model-assisted coding validated against human assignment
Statistics: chi-square with permutation p-values, Fisher's exact, Mann-Whitney U, Kruskal-Wallis, ordinal and binary logistic regression, two one-sided tests for equivalence, Haberman post-hoc residuals, Benjamini-Hochberg and Bonferroni correction, Cramer's V and rank-biserial effect sizes
Data and infrastructure: Kafka, Spark Structured Streaming, DuckDB with dbt models and schema tests, Airflow, MLflow, Evidently drift monitoring, Docker, FastAPI with Pydantic validation, Databricks, Azure Synapse, Scala, SQL
Collection and linkage: REST API harvesting with cursor pagination and rate limiting, PDF text extraction, record linkage, deduplication, schema reconciliation across mismatched sources
The projects here were built with substantial AI-assisted coding. Problem formulation, method selection, experimental design and interpretation are my own; AI was used for implementation scaffolding, and every result was validated against source. Each repository documents this.
