Work History
AI Engineer
Alagora (EdTech Start-up)
Hamilton, Canada
05.2025 - Current
- Co-led a 3-person AI team developing an automated grading pipeline for business case-study reports, slashing professor grading time from approximately 30 hours to under 8; the system generates structured per-rubric scores and feedback, stored in PostgreSQL, and editable via instructor controls
- Designed a modular multi-agent architecture with LangChain, featuring callable Python modules for rubric parsing, case retrieval, and submission analysis; enforced schema-controlled prompts and outputs, with instructor edits supported through a Flask API and React frontend
- Built differentiated document pipelines: chunked and indexed case files into FAISS using sentence embeddings for efficient retrieval-augmented prompts, while preserving full student submissions for holistic evaluation—reducing token usage by approximately 60% without compromising
- Engineered rubric-to-principle conversion logic, transforming criteria into JSON rules; each principle triggers targeted prompts to compare submission arguments against case context, producing per-principle scores and justifications for faculty review and optional revisions
