I'm an Engineer, with a background in Artificial Intelligence, and I've always sought to use technology to solve problems. In my Master's, my study focused on Artificial Neural Networks, and I've published scientific articles and produced a dissertation on the subject. In the last four years, I've dedicated myself to studying Data Science (Python, ML, SQL, Spark). I'm responsible and a team worker. During my career, I've taken on several managerial roles, having even led remote teams. I know how to work with other people and try to treat everyone with respect and courtesy. I'm always open to hearing suggestions, criticisms, and other perspectives. I have just finished the Data Science Bootcamp with the french school Le Wagon. It was an amazing experience and I was able to further consolidate my skills in Data Science: statistics and probability, SQL, Python (Pandas, Numpy, Sklearn, PyTorch, Tensorflow/Keras), NLP, MLOPs basics (Google Cloud). I am searching for new challenges and experiences, and I believe I can make valuable contributions.

Lucas P.

Vetted Sentiment analysis developer in Brazil (UTC-3)

I have a Bachelor’s in Computer Science, a Master’s Degree in Data Visualization, and a double Ph.D. in Machine Learning The latter was a research focused on Time Series Forecasting and performed in partnership with the University of São Paulo (Brazil) and Rijksuniversiteit Groningen (the Netherlands). Since my Ph.D. in 2020, I have worked on several projects as a Data Scientist for fintechs and telecommunication companies. Despite being mostly a Scientist, I am also used to performing Engenieer’s ETL as I am generally involved in early production steps such as client conversation and data retrieval to match project demands. My last model achieved a KS of 0.67 and remained stable in production with PSI under 0.1. I am also excited to increase my experience with LLM and always be ahead on state-of-art methods. As a curiosity, I like to swim and have siblings in Madrid. I go to Spain when possible and can speak Spanish if necessary.

Renan F.

Vetted Sentiment analysis developer in Brazil (UTC-3)

I work as an analyst on AB testing projects and have good experience in process methodology due to my entrepreneurial past. My background in management, front-end programming, digital product design, and research expands my vision when it comes to project development in technology. Since I was a child, I have always been passionate about computer science. As time went by, I inserted it more and more in my daily life, until I decided to transition my career once and for all to the development area. As time went by, I discovered in user experience (UX) studies a perfect way to apply my knowledge in Front-end, since I love working with people. I consider my successful experience as an entrepreneur one of my greatest professional achievements since the journey to establish and consolidate a new business in the market is full of obstacles. My biggest challenge is at home since my son Arthur was recently born and brought with him more responsibilities and a new world full of new learnings. My short and medium-term goals are to expand my programming knowledge even more and consolidate myself as a senior developer.
