    I'm a flexible developer with experience in building from containerized applications running on cloud providers (AWS) in order to tackle high complexity mathematical problems to simple APIs and business services. - Strong Python experience integrating APIs and optimizing web advertising operations mainly, in the header biding space. - Statistical and Machine learning experience (Tensorflow, Keras, Theano, PyMC3, Numpy, Pandas, dhHaskell) - Experience working in a developer team (git, GitHub, GitHub Actions, AWS). - I believe regular communication is vital for a project's success. Online conference services (Meet, Zoom, Teams) are preferred, after the meeting I always provide a meeting briefing for project traceability and management. - If you need a skill I didn't mentioned I'm more than happy to learn it and master it! Review from one of my clients: "First off, Enrique is very intelligent and is able to learn and grasp new things quickly without having the need to explain him what the project is about. Secondly, he is very disciplined when it comes to meeting the deadlines of the project. Thirdly, he has got a wide array of skills which makes him invaluable in addressing the task at hand. I would definitely love to keep on working and collaborating with him in the times to come. From literature review to Machine Learning to Bayesian Statistics to software product development, he has got all the necessary skills and is able to deliver on each of the fronts. Strongly recommend!!" We have worked with Enrique Löser on several projects that involved complex algorithm design and heavy programming workload. His dedication and professionalism have made a lasting impression on our company. We look forward to work with him fro many years to come as it's very rare to come across this mix of talent and responsibility in the market. He always delivers on time and goes above and beyond to design the tools and software we only were able to envision in our imagination.

    Data Scientist specialized on Machine Learning, Supervised Learning, Deep Neural Networks, Recurrent Neural Networks and Reinforcement Learning. I have worked on a wide variety of industries: finance, bank, hedge funds, manufacturing, technology, domain names, horse wranglers and betting games. With machine learning I have produced stock market strategies with a compound annualized return near 20% (yearly), which are currently publish on my web page (see below). In 2022 I was certified as AWS Machine Learning Specialist. The first 10 years of my professional career I had worked as a backend developer, coding high availability services on Python, C, Java and Perl. Since 2012 I am working full time as a data scientist. I enjoy machine learning. I am not a standard data scientist: I have studied the implementation details of the main ML algorithms, allowing me to customize them according to the nature of the working problem. Since 2014 I am working developing ML models freelance, on the Upwork platform. I have more than 11,000 net hours, 35 different jobs, ranked with 4.99 stars and 100% job success rate. - Programming (currently): Python - Programming (past): R, Perl, Java and C. - Machine Learning Models: Naive Bayes, Fisher Discriminant Analysis, Nearest Neighbor, Multivariate Regression, Logistic Regression, Decision Trees (Chaid and CART), Support Vector Machine, Genetic Algorithm and PSO - Ensembles: Random Forest, Gradient Boosting Machine, Bagging and Boosting - Deep Learning: Traditional Neural Networks (Backpropagation, CPN, SOM), Deep NN, Convolutional NN, Recurrent NN, LSTM and Bidirectional Recurrent NN.
