I’m a life sciences researcher and data analyst with an MS in Biotechnology (GPA 4.0, Florida Institute of Technology, 2026) and a BS in Biology with a minor in Animal Behavior (Indiana University, Magna Cum Laude). I build statistical workflows, analyze complex biological datasets, and write clearly for scientific audiences. During my graduate research at Florida Tech, I replaced a $1,000+/year paid data collection platform with a custom open-source R solution, designed automated field data workflows, and integrated multi-source environmental data into reproducible pipelines. As an undergraduate researcher at Indiana University, I analyzed multi-year GPS wildlife tracking datasets, cleaned long-term behavioral observation records, and built the lab’s first searchable specimen database from 40+ years of archival records. WHAT I CAN DO FOR YOU - Statistical analysis: regression, mixed-effects models, hypothesis testing, descriptive statistics - R and Python scripting and pipeline development - Data cleaning and transformation from messy, multi-source datasets - Publication-quality visualizations with ggplot2 and matplotlib - Reproducible reporting via R Markdown and Jupyter Notebooks - Scientific writing: Methods, Results, and Discussion sections - Literature reviews, grant background sections, and lay summaries - Manuscript editing for clarity, accuracy, and journal style My background spans field ecology, molecular biology, and computational data science. I work equally well with observational biological data, commercial analytics datasets, and structured clinical data. I’m detail-oriented, deadline-driven, and used to communicating complex findings to non-specialist audiences (I’ve taught college biology). Whether you need a quick data clean-up or a full analysis pipeline with a written report, I can help. Message me with what you’re working on. I reply within 24 hours.

I help businesses turn data into decisions that drive results. With an MS in Mathematical Finance & FinTech from Boston University and hands-on experience at a primary US Treasury dealer, I bring a rare combination of quantitative finance expertise and modern data science skills. What I can build for you: - Financial data dashboards and automated reporting - Machine learning models for prediction and classification - NLP pipelines for sentiment analysis and text analytics - RAG-powered AI tools using LangChain and OpenAI - Quantitative models for risk analysis and financial forecasting Recent projects include a real-time Financial News Sentiment Analyzer using RAG and GPT, a Bank Customer Churn prediction model, and an interactive Financial Data Dashboard, all deployed and live. I work in Python, SQL, Pandas, Scikit-learn, LangChain, Streamlit, and PySpark. I deliver clean, documented, production-ready work. If you have a data problem that needs solving, let's talk.

My goal is to provide solutions that meet or exceed my clients' expectations. I have a B.S. in Computer Science and a Minor in Mathematics. I have developed applications and scripts using over a dozen programming languages, and specialize in working with data. I am an Excel/Access expert and can automate these applications. I have worked with relational databases, including Microsoft SQL Server (2005, 2008R2, 2014, and 2017). I have reporting and data visualization experience using SSRS, Excel and Tableau. Additionally, I have experience working with APIs, Google Sheets, and App Scripts. I welcome any requests, big or small.
