Hire the Best Demography Professionals

I turn messy environmental, agricultural and geospatial data into decisions. Not just maps and shapefiles, the forecast, the dashboard and the answer your team can act on. I am a Data Scientist and Forest Engineer with 10+ years of experience. I currently lead the Data Intelligence area for the Planning Advisory Department at IDR-Paraná, where my pipelines support 399 municipalities and inform an agricultural and forestry sector worth billions. In practice that means I do four things most GIS freelancers do not do together: Geospatial data engineering. Production Python + PostGIS pipelines that pull multi-source data (satellite, census, trade, land prices, field data) into clean, reproducible datasets. Scheduled and tested with GitHub Actions, not one-off scripts. Machine learning on spatial data. scikit-learn and PyTorch models for time-series forecasting, clustering and segmentation, and collaborative filtering. The “what does this mean and what happens next” layer, not just the map. Decision dashboards. Interactive Plotly/Dash and Power BI dashboards that stakeholders actually use to decide. I built Datageo Paraná, a public platform with 10 interactive dashboards spanning 30+ years of data and 400+ products (VBP, census, ComexStat, employment, land prices, forestry prices). Domain depth. Forestry, agribusiness, sustainability and public-sector analytics. I have led FSC- and NR-31-compliant operations across multi-million-hectare projects, so I understand the data and the decisions behind it. What you get when you hire me: a clear scope up front, fast and direct communication, a documented methodology, original analysis (never recycled or plagiarized), and a full handoff of the maps, the validated pipeline and the code. You own everything at the end. Tools: Python, PostGIS / PostgreSQL, QGIS, scikit-learn, PyTorch, Plotly/Dash, Power BI, Supabase, GitHub Actions, GDAL/GeoPandas/Shapely/rasterio, SQL. Good fit if you need: satellite / remote-sensing analysis, geospatial web scraping and data acquisition, spatial data pipelines, forecasting or segmentation on geographic data, interactive geo dashboards, or forestry / agribusiness / environmental decision analytics. If you have geographic data and a decision to make, message me. I will tell you honestly whether I am the right fit and what the smallest useful first step looks like.

My current and future work focuses on decision-support systems that help communities, agencies, and industries align decarbonization with sustainable land management, forest resilience, environmental quality, and regional economic development. Research and career themes: · Circular bioeconomy and low-carbon fuels: renewable diesel, sustainable aviation fuel, hydrogen, biochar, and bioproducts from forest, agricultural, and urban residues. · Climate-resilient landscapes: biomass utilization as a strategy to support forest health, hazardous-fuel reduction, wildfire-risk mitigation, and rural economic resilience. · Geospatial decision support: GIS, MCDA, feedstock logistics, facility siting, land suitability, and transportation analysis for bioenergy and environmental planning. · Carbon accounting and policy analysis: LCA, TEA, carbon removal, avoided emissions, social/environmental justice co-benefits, and policy-credit frameworks.

Transforming complex spatial data into actionable insights and professional-grade cartography. With 12+ years of expertise as a GIS Specialist and Geographer, I help businesses, researchers, and government agencies solve spatial problems through advanced analysis and high-end map visualizations. I bridge the gap between technical ArcGIS/QGIS modeling and the design excellence of Adobe Illustrator. What I bring to your project: - Advanced Spatial Analytics: I perform deep multivariate analysis (PCA, Cluster, CCA) to uncover hidden patterns in demographic, environmental, and socioeconomic data. - Professional Cartography: Publication-ready maps refined in Adobe Illustrator for high-impact reports and presentations. - Specialized Domains: Expertise in Urban Geography, Geomarketing, Risk/Vulnerability Assessment, and Biogeography. - Software Mastery: Full Esri Suite (Pro, Online, Dashboard, Survey123, Field Maps, Experience Builder), QGIS, Global Mapper, and gvSIG. Whether you need a deep dive into urban zoning or a visually stunning map for your project, let’s discuss how I can help you visualize your data.

Hi there! 👋 During last 7 years, I helped many researchers to conduct statistical analysis, find interesting insights and interpret them correctly, as well as carefully prepare their papers to the publication. Conducted analysis across various fields — medicine, psychology, economics, ecology, genetics. I can always clearly explain, what I am doing and why I think this is the way to do it. If you need actual results, accurate and useful — write me! 👉 Expert in statistics, research methodology, bioinformatics 👉 Skilled with R, Python, SQL, SPSS, Stata, Excel 👉 Deep understanding of regression, time-series, survival analysis 👉 Never missed a deadline

Do you need someone who can handle your entire data journey? From collecting data, to analysing it, to automating the processes around it, and finally presenting it in a stunning, interactive dashboard? You've found that person. I'm Catherine, a data analyst and statistician with deep expertise across the full data pipeline. I don't just run numbers. I help you collect, clean, analyse, automate, and visualise your data in a way that drives real decisions. What I bring to your project: 📊 Statistical analysis & research: Hypothesis testing, regression, SEM, survival analysis, psychometrics/scale validation, and econometric modelling using SPSS, R, Stata, Python, Jamovi, and JMP. I've contributed to peer-reviewed journal publications through my statistical work on surgical databases (NSQIP). 🔍 Qualitative research: Thematic and content analysis using NVivo, MAXQDA, and Atlas.ti for interviews, focus groups, and open-ended survey data. ⚙️ Automation & workflow design: I build end-to-end automated pipelines using Make and Google Apps Script, including integrations with Stripe, Google Forms, Google Sheets, landing pages, and more. Recent clients have seen their manual data workflows fully automated. 📈 Dashboards & data visualisation: Interactive executive dashboards in Power BI and Looker Studio, tailored for marketing teams, operations, healthcare, and finance. I turn raw data into clear, compelling visual stories. 📋 Survey design & data collection: End-to-end survey projects using Google Forms, Typeform, and Qualtrics, including automated data pipelines from form submission to clean, analysis-ready datasets. I've worked across yachting, healthcare, finance, and academia, and I also offer tutoring in SPSS, R, and Stata for students and professionals. Let's talk about how I can support your project.

I’m a GIS Specialist with 4+ years of hands-on experience in spatial analysis, remote sensing, and environmental modeling.
