    My name is Cláudia Rodrigues and I'm passionate about marketing and data science. I currently work as a Marketing Analyst and Content Creator. On my day to day I deal with SEO analytics and provide strategic insights for Marketing efforts. Recently I finished my post graduation in Data Science and Big Data Analytics at Universidade Estácio de Sá. I have a Business degree in at the Federal University of Rio de Janeiro (UFRJ). In addition, I am coursing a Descriptive Statistics course to further my analytic abilities and get me ready to work with machine learning. I believe my previous experience in business has provided me a world view complementary to the data scientist role. I am able to understand market needs, management demands and the necessities of different departments, besides only working on technical aspects of the data analysis process itself. In my previous job I had the opportunity to develop a project of development of the northwest region of Rio de Janeiro, involving aspects of education and basic sanitation. The internship allowed me to associate theory and practice with the use of administration. I learned how to use time and project management tools. As far as soft skills are concerned, I have strong leadership skills, communication skills and discipline. I like to work both in teams and alone and have previous experience working remotely. Up until 2021 I was working as a virtual assistant at a software company called Begeeked Labs. I was in touch with developers everyday and saw the day to day of development of a number of projects from beginning to end, such as Discord.me. I was daily in touch with the Agile methodology. In terms of research and Scientific Method, I've had a lot of experience doing research in the University as I was part of a research program called PEP (Programa de estudos e Pesquisas em Desenvolvimento Humano, Formação de Lideranças Transformadoras e Governança Social), oriented by Professor Doctor Ricardo Rohm in a team of excelent students. The program consists of research in the fields of Human Development, Formation of Transformative Leadership and Social Governance. The research I made with my team was about Social Entrepreneurship and Transformative Leadership. I believe I have gained a lot of experience working with the scientific method, necessary to the process of data science.

    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.
