I'm an AI engineer. I build systems around models -- retrieval pipelines, agentic frameworks, finetuned VLMs. From research to production.
My work spans the full stack -- finetuning vision-language models, building eval pipelines, designing hybrid retrieval architectures, and shipping production backends.
On The Porch -- Multimodal civic intelligence agent for Dorchester, Boston
Hybrid SQL + RAG with a 3-mode query router (95% routing accuracy) and retrieval caching. Cut response latency from 15-20s to 2-3s.
LangChain Chroma MySQL Gemini FastAPI
Boston Housing Violations -- End-to-end civic ML pipeline (BU Spark!)
16K+ violation records, multi-dataset integration, 90% accuracy violation prediction, temporal anomaly detection, geospatial heatmaps.
Scikit-learn Folium Pandas KMeans
Spatial Reasoning in VLMs -- Multimodal ML research
Fine-tuned LLaVA-1.5-7B with LoRA for spatial reasoning tasks. Turns out explicit CoT prompting actually hurts performance here. Interesting find.
PyTorch HuggingFace PEFT LoRA LLaVA
Anime Recommender -- Agentic hybrid recommendation system
16M+ user ratings across 28K anime entries scraped via MyAnimeList. SVD-based collaborative filtering + content similarity, all wrapped in an agent tool layer.

Restaurant Reservation Chatbot -- LLM tool-using agent with human-in-the-loop
Natural language booking requests routed into structured backend ops, with an admin approval workflow keeping humans in control.
FastAPI SQLite Gradio OpenAI
AI Research Curator -- Two-agent system that learns what you care about and gets better at it every day. One agent runs daily, scrapes the web, scores content against a preference vector in embedding space, and writes you a briefing. The other captures how you engage with that briefing and feeds signals back to drift the vector. Cold start to personalized in a few cycles.
