Data Wizard & Mentor | Helping data nerds launch & advance their data careers | Sr. Data Analyst | MS Analytics

Thanks for checking out my page! I am a data professional with years of experience in data analysis, data visualization, machine learning, dashboarding, and other data requirements.

I am an engineer turned data expert with extensive experience providing insights through data. I discovered my passion for data while completing my B.S. in Chemical Engineering and I went on to receive my M.S. in Data Science & Analytics!

I am a strong critical thinker, with robust technical skills that are healthily balanced with intuition and an innate ability to communicate data. I live to see the lightbulb moment when I’m discussing topics with people!

How can we help each other?

Throughout my schooling and professional career, I have always enjoyed helping my peers and coworkers. With LinkedIn and Medium, I'm casting a wider net! Reach out, connect, follow, or just pass through. Whatever floats your boat and best of luck on your journey!

•Context-Aware QA Chatbot: slashing client data retrieval time by 60% using 
Python, Langchain, and IBM Granite 3.2 LLM, integrating Elasticsearch for 
precise, data-driven answers from Proprietary datasets.
•Enterprise Scalability: End-to-End delivery (development through deployment) of 
scalable Generative AI and LLM solutions, customized to client workflows, 
demonstrably enhancing system performance and operational agility.
•Engineered autonomous AI agents using CrewAI and Llama 3.3, achieving a 40% improvement in decision making accuracy and response timeliness. Architected an intelligent framework that empowered the agent to dynamically select the optimal tool RAG for contextual data, a math tool for calculations, or real-time web search based on the user’s query. This multi-tool capability enabled robust, multi-step reasoning, allowing the agent to overcome base LLM limitations and deliver highly accurate, context-aware solutions.
