    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'm experienced in writing MATLAB scripts to model, simulate and control a wide variety of dynamical systems and create optimization routines. I'm also experienced with C++ and Python. One example of something I've done in C++ is using the open-source library PSOPT to solve an optimal ascent trajectory of a rocket launcher. In Python, I wrote a simple algorithm to count plants of images with the OpenCV library. I'm currently working on the simulation of satellite orbits, and the objective is to quantify how much error is inputted into the dynamical model by using a less accurate and decreasingly complex gravitational model. This project requires knowledge of C++, Python, and MATLAB.

How can automatically scale up and down my solution to support more users with minimal cost? 4. How can monitor my solution performance in production? 5. When do I need to retrain my model? 6. How can I manage my infrastructure to improve costs and reliability? I am an experienced Researcher and Machine Learning Engineer with a Ph.D. and more than 5 years of practical work in the design and build of scalable machine learning solutions on top of open-source and enterprise products. I've built and deployed several Computer Vision and NLP AI solutions applying best practices to providing a technological backbone for managing the machine learning lifecycle through automation and scalability. I apply Machine Learning Operations (MLOps) best practices to make the development and deployment of machine learning systems more systematic, repeatable, and reliable. My specialties are: ✅ Machine Learning Operations (MLOps) to unify the release cycle for machine learning and software applications; ✅ Build data and ML pipelines to automate training and deployment; ✅ Automated testing of machine learning artifacts (e.g. data validation, ML model testing, and ML model integration testing); ✅ Deploy Machine Learning solution in the Cloud (GPC and AWS) or on-premises; ✅ Build Machine Learning models to solve Classification, Regression, and Computer Vision and NLP problems; ✅ Build APIs for operationalizing your models and analytics; ✅ Containerized Machine Learning solutions to run in Docker and Kubernetes; ✅ Python development with several ML frameworks (Pytorch, TensorFlow, Keras, scikit-learn, etc.); ✅ Data Version Control; ✅ Code versioning with Github/GitLab/BitBucket; The client review below which you will find in my reviews section and numerous others like it describes the quality of work and value that you can expect from working with me: "From my perspective Patrick has great programming and machine learning skills and business understanding. He was able to find a creative solutions which increased accuracy of the computer vision model. His software is well documented and very easy to use. Patrick shows initiative and has strong work ethic. I'd like to work with Patrick again in the future on various Machine Learning projects" You can see more about my work on my website: cpatrickalves.com I am also a quick learner and team player who shares knowledge and ideas with colleagues. Send me a message and let's talk about your project.

    I am pursuing my Master's in Applied Mathematics and since the beginning of my undergrad I've been trying to develop a very horizontal, interdisciplinary formation, which is most organic to me since my interests span a wide range of -- often intertwined -- topics. My core technical interests are within the grand areas: Artificial Intelligence, Pure & Applied Mathematics, Theoretical Computer Science, Complex Systems, and Network Science. I have an extensive mathematical background and solid programming experience. A driving problem that could be said to be the connecting thread between all of these interests is that of further understanding "intelligence" as an emergent phenomenon that arises from the dynamics found within and between complex adaptive systems.
