What I'm looking for

I'm looking to build and deploy practical AI/ML solutions, especially LLM, RAG, NLP, and computer vision products, with collaborative teams and modern cloud and MLOps practices.

I'm building Smart Owl at Southern New Hampshire University, a multi-agent student-support chatbot that combines GPT, LLaMA, DBRX, LangChain, LangGraph, RAG, and Databricks vector search.

I've delivered AI/ML solutions across education, healthcare, and regulated use cases, including BERT-based healthcare Q&A, compliance-aware LLM prompting, SQL generation from natural language, and a CNN that achieved 97% accuracy in X-ray image classification.

I deploy end-to-end systems with Python, PyTorch, FastAPI, React, Databricks, AWS, Docker, MLflow, PostgreSQL, Redis, and DynamoDB, with a focus on reliable model lifecycle management and practical user experiences.
