Data Scientist | Environmental Modeling & Analysis Hi! I am a data scientist specializing in environmental modeling and analysis. I am available for freelance projects involving: ✅ Data Analysis & Visualization – Exploratory data analysis, interactive dashboards, geospatial analysis, and insightful visualizations to support decision-making. ✅ Statistical Testing & Modeling – Hypothesis testing, regression models, machine learning, and predictive analytics tailored to complex datasets. ✅ Hebrew Language Expertise – Translation, proofreading, and linguistic analysis for scientific, technical, and general content in Hebrew. I have a strong background in ecological and environmental data, combining scientific expertise with advanced analytical techniques. Whether you need in-depth statistical insights, predictive modeling, or interactive data tools, I can help you turn complex information into actionable results. Feel free to send me a message—I’d love to discuss your project and see how we can collaborate!

I’m a Data Analyst and Scientist with a PhD in Atmospheric Science and over 7 years of experience in data analysis, statistical modeling, and visualization. During my time at the Max Planck Institute for Chemistry, I developed Python-based tools to process and interpret complex environmental datasets. My expertise includes Python (pandas, NumPy, scikit-learn, Matplotlib), machine learning, data cleaning, and exploratory data analysis. I specialize in turning raw data into actionable insights through clear, efficient, and reproducible workflows. I’m available for remote projects and enjoy helping businesses and research teams make data-driven decisions. Additionally, I occasionally take on English–German translation projects, especially in the fields of science and technology.

I’m a Data Scientist and Physicist with a strong background in computational modeling, machine learning, and environmental data analysis. I hold a Master’s degree in Physics with a focus on theoretical and computational methods and a minor in Computer Science. I bring over five years of hands-on Python experience and a solid foundation in scientific computing, statistics, and data visualization. My work combines analytical precision from physics with modern AI tools to solve real-world data problems. I’ve developed simulation pipelines for computational and numerical physics (including numerical relativity) and created machine learning models to predict and analyze complex environmental and scientific data. Core Skills: - Programming: Python, C++, Bash, R, SQL - Data Science & AI: scikit-learn, PyTorch, NumPy, Pandas, SciPy, PCA, clustering, cross-validation, neural networks - Visualization: Matplotlib, Seaborn - Domain Expertise: Climate and environmental data, physics simulations, numerical modeling - Other: Feature engineering, statistical analysis, workflow optimization, scientific reporting What I Offer: - Clean, reproducible, and well-documented code - Insightful analysis and clear visualizations - Deep understanding of data-driven scientific and environmental problems - A reliable, research-minded approach to complex challenges I’m passionate about using data and AI to understand complex systems, whether in climate, physics, or applied analytics. If you’re looking for someone who combines scientific rigor with practical programming skills – I’d love to collaborate on your next project!

After my PhD and some postdoc work, I've spent over a decade in various support-related roles because I really enjoy helping people and being at the rear, developing solutions that push scientists and innovators forward into our future. I've worked on many different types of projects, but my primary goal on Upwork is to work with clients needing support with GRANT WRITING. Here's a bit about the types of grants I've already had the honor of preparing proposals for: - EU Marie Curie International Incoming Fellowship. - EU Horizon grants. - Innovation grants. - Federal grants. - Foundation grants. - Scholarships. Topics: Life Sciences (agriculture, sustainability, microbiology, ecology, environment/climate change, biodiversity, microbiome, etc.) If you're looking for other types of services, here are some other ways I can also help you: - Technical, scientific, and popular science writing. - Editing and proofreading (I have a certificate). - Biological data analysis. Feel free to message me directly to discuss your specific needs and agree on a price. I look forward to working with you!

I'm an Upwork Expert-Vetted Data Scientist who covers what usually takes two specialists: classic ML and modern LLM systems, shipped to production. Nobody understands your business like you do, and you know exactly the bottleneck you want gone. You want someone who can see it just as clearly, bring it to life the way you imagined, and build it to last. That has been my track record. Imagine handing off your idea, and what comes back makes you say, "This is exactly what I had in mind!" That is the feedback I hear most from my clients. Here's what working together looks like: You explain the vision. I turn it into a clear plan, build the system end-to-end, and ship something your team can actually run and trust. Whether it's an LLM or RAG application, an AI agent, or a forecasting or anomaly-detection engine, it is handed over to you already deployed in production, documented, and yours to keep building on. What my clients say: → "She took our vision as her own and brought it to life." → "When she says she'll handle something, it's done." → "Hwei is the proverbial needle in a haystack. She gets it. She gets it done." Recent projects: • A US women's health startup: I led the AI intelligence layer behind their production multi-agent chatbot, live ahead of their fundraise. • A Fortune 500 consumer brand: I built a shelf-life forecasting platform that turned weeks of manual modeling into 30-second predictions. • An Italian telecom firm: I built an LLM document validation pipeline that cut compliance review from days to minutes, with zero false approvals against their own 99.7% precision target. • A Dutch water consortium: I built an anomaly-detection system that caught real contamination with zero false alarms, then grew it into a 12.3M-measurement data platform that their own team can run without a developer. → Expert-Vetted · Top 1% on Upwork · 100% Job Success → ML and AI since 2018 · 8 published papers · Trained at Fraunhofer SCAI and the University of Hamburg Tell me what you're trying to build, and I'll reply with a clear path forward, built around your goals. ================== Tools and capabilities: • Generative AI and LLMs: large language models, RAG (Retrieval Augmented Generation), AI agents and multi-agent systems, chatbots, prompt engineering, LLM evaluation, vector databases, LangChain, Pydantic AI • Machine learning: predictive modeling, anomaly detection, time series forecasting, predictive maintenance, statistical analysis, deep learning, computer vision, natural language processing (NLP) • Engineering and delivery: Python, FastAPI, Docker, cloud deployment (AWS, Azure, Render), data analysis, data pipelines, interactive dashboards (R Shiny, Streamlit, Gradio), data visualization • Model APIs: OpenAI, Anthropic Claude, Google Gemini, Hugging Face • Consulting: artificial intelligence (AI) strategy, AI implementation, AI consulting, code audits, knowledge transfer
