Generating a lot of data but not making sense of it? Overwhelmed by the latest trends in Data Engineering and Artificial Intelligence? Need someone who can speak in business terms while also having strong technical expertise? I've been working with Upwork since 2016, and am proudly part of the top 1% (Expert-Vetted) program. I'm not an agency nor would likely become one, all work is done by myself. I've built the information structure of several companies across the globe in Marketing, Financials, E-commerce, and Agribusiness - regardless of their size. I've worked for 1000+ employees companies and small shops accordingly. I usually report directly to the CEO as CTO/CIO, to the C-level as data lead, or can also act as a team player - brain for hire for bigger teams. I like all kinds of challenges. What I can do: - Take your raw data, process and present it in a meaningful and reproducible way. My goal is to keep you aware of what's happening (in plain language, if you're a non-tech person) and to work together with your team (if you already have a tech structure) on every step of the process - from data extraction to final presentation. - Create (or advise you on how to build) new interfaces to update your existing systems with insights and KPIs derived from Business Intelligence and AI projects. - Suggest the best course of action and best practices for your situation. No matter your size. - Audit your existing information structure and point you to new possible revenue sources or cost reductions. If that resonates with what you need, get in touch. I'm always happy to help. For those techs out there, I usually work with: - R - Python - QlikView / QlikSense / QlikCloud - PowerBI - Tableau, But I've also worked with Klipfolio, Chart.io, and many other tools. I've developed interfaces and APIs for - OpenAI (ChatGPT) - Ai-Pro (Claude) - Google Analytics - SAP R/3 and HANA - Unleashed Software - Monday.com - ZOHO CRM and Campaigns - InfusionSoft - ActiveCampaign - GIS tools (ArcGIS, QGIS, PostGIS). What I also do: - Snowflake, Amazon & Azure datawarehousing - SQL querying and tuning (MySQL/MS SQL Server/PostgreSQL) - Big Data processing - Forecasting models - Marketing effectiveness analysis

I graduated in economics in 2016. Next year I began studying for my master's degree application exam. My objective was to learn statistics and finance. So I was accepted and started my master's degree in 2018. Unfortunately, the institution I picked did not have a focus on statistics and finance. During my last semester, my frustration and problems with my advisor left me somewhat unmotived to finish my dissertation. So I went my master's degree. Since my graduation days, I have studied coding. I always thought that having the ability to gather, process, and analyze large amounts of data would be valuable in today's world. My first coding experience was with MATLAB and C/C#. MATLAB, my brother used to work with it, and I used to fiddle around to learn how to code ( did nothing special ). C/C#, I did a two-week tutorial I found online. Although I never used these two program languages later, they helped teach me some concepts in programming. While in my graduation, I started using the program languages R and Python. R I used due to its extensive statistical packages support, and the second to its more general usability. During My master's degree, I found myself doing some paid R coding. Usually, it was simple data inference, like running some simple code to find the best linear regression model with variable permutation. Furthermore, I did have some coding experience with Python in helping some research groups in reading SQL databases and scraping online data. After I exited my master's degree, early 2020, I did freelance coding data analysis ( ex.: Inflation prediction models ), machine learning ( ex.: House prediction models in Rio de Janeiro ), and data scraping. I have a Github page with examples github.com/marcoaurelioguerrap ( Although still in Portuguese, my native language. ). If you need statistical models for prediction, inference, or data to be scraped, or organized I might be helpful. Other knowledge I have are Risk Management ( VaR, ES calculations ), stock and options market backtesting, options price models ( BS, Monte Carlo, and SABR ), test for forecast Bias, regressions ( OLS, Logit, probit, Tobit, panel data, time series, GMM, ARIMA, GARCH ). less

I am an experienced Ecological Modeller and R Programmer, with a passion for creating data-driven insights for conservation and biodiversity. My expertise in Spatial Ecology and Ecological Niche Modelling allows me to effectively model and analyze complex ecological systems using R programming. Over the past two and a half years, I have developed a strong understanding of spatial analyses and modelling in R, and have become well-versed in acquiring, cleaning, and georeferencing both species and climatic data. I have worked with multiple models, including eight different algorithms of three families: Tree-based, Regression-based, and Machine-Learning. I am also proficient in most spatial related R packages (raster, sp, terra, sf, tmap, leaflet, rayshader) syntax and the back and forth between them. In my recent work, I have extended my expertise beyond Ecological Niche Modelling to a wide range of quantitative modelling approaches, including quantitative population genetics, epidemiology, and network ecology. I have experience using various approaches such as game theory, differential, and markov processes. I have a strong research background in Macroecology, Biogeography, Evolution, and Ecological Niche Modelling. My work has led me to take an interest in computational and spatial ecology. Modelling ecological systems is what delights me, and I am fascinated by what can be achieved through math and code alone, and how much we can explore of the natural world through this lens. In addition to my research experience, I have also developed my own R package, sdmLit, which allows users to apply tools that analyze model performance, check environmental consistency, and build ensemble models by frequency to Ecological Niche Models. This package automates the data manipulation process and makes it easier to use literature methods, which previously required several thousand lines of code. My dedication to ecological modelling and R programming has helped me to become a skilled and detail-oriented professional. I am always eager to learn and take on new challenges, such as implementing individual-based models in spatial settings. I am confident that my skills and expertise can bring value to any project related to ecological modelling, data analysis, and conservation. If you are looking for a dedicated and knowledgeable Ecological Modeller and R Programmer, please don't hesitate to get in touch.

Machine learning, mathematical modeling, and data analysis are the core of my skills. I can use existing techniques of diverse environments and easily adapt to different environments and frameworks. I can use these techniques in a wide range of applications, which include: radar image processing (SAR images), face recognition, natural language processing, marketing problems via GAMLSS, and remote sensing in Medicine (I took part in an awarded publication on this subject). Usually, I will ask you to describe your problem and your desired method of solution, if there is one. I can provide novel solutions that the client might not be aware of, and I usually bring this up during meetings and briefings if convenient. When not working in a team, I am very comfortable being the one to translate the practical situation to the mathematical setting and then present my solution, so feel free to contact me if all you got is a problem without a hint about the solution. I also enjoy very much discussing the solution with the client. Timely communication is important since I work a particularly demanding job as a teacher/researcher. It is very important to let you know that I am only available outside my daily work hours, which go from 08:00 to 17:00 (GMT-3 timezone) and weekends.
