Finding months in each warehouse with abnormal average number of orders, profitsand profit margins -

It also makes other types of predictions and it creates graphs.• ML (KModes) for grouping employees• Finding employees that have high salaries or low salaries for their group. -
Machine Learning EngineerRaiffeisen Bank Romania Sep 2022 - Aug 2023Bucharest, Romania• Gathering macroeconomic data.• Tried an AI that would figure out what to send to clients (SMS, letter, voice call, robot) that would maximize the chance that a client would pay and also maximize the amount of money collected from the client, while minimizing the cost. -

ConsultantPhi Partners Oct 2021 - Jan 2022Bucharest, Romania• Worked in Fusion a little bit. -
Data ScientistTotalsoft Aug 2021 - Sep 2021Bucharest, Romania• LSTM neural network for identifying personal identifiable information from json files with 98% accuracy.• LSTM neural network for identifying if a first name is an actual person’s name using a dataset with names from 17 countries with an accuracy of 92%. -
ConsultantDeloitte Apr 2021 - Jun 2021Bucharest, Romania• Long run average for probability of default.• Climate change stress test for individual economic sectors. Macroeconomic model taken from a British Research Institute which give projections for employment, GDP, etc. depending on carbon tax emissions that governments impose. Those macroeconomic predictions were digressed to individual sectors by using a model published by Banque de France. -
Postdoctoral ScholarWorcester Polytechnic Institute Aug 2019 - Jan 2021Worcester, Massachusetts, United States• Created another alternative to the Black‑Litterman models I worked on during my Ph.D. This alternative incorporates a stochastic volatility model on the data’s common factors. In this way, the covariance matrix of the data is not only random, but also changes with time. Paper published in the InternationalJournal of Statistics and Probability: https://www.ccsenet.org/journal/index.php/ijsp/article/view/0/44571.• Taught Calculus 2, Linear Algebra 2, Regression Analysis and Applied Statistics I. -
ResearcherUc Santa Barbara Jun 2016 - Jun 2019Goleta, California, United States• A Bayesian Approach for Asset Allocation– Mathematically derived two variations of a model that takes as inputs both historical data and any prior information that the user might have about the linear relationships between the means of different populations. It outputs posterior means, posterior covariance and possible percentage weightsfor each population. The models maximize the posterior mean, minimize the posterior covariance and the Bayesian risk.– Complete work published in the International Journal of Statistics and Probability: http://www.ccsenet.org/journal/index.php/ijsp/article/view/0/42740• A Bayesian Approach for Large Asset Allocation.– Encountered running time and memory allocation problems when applying one of the Bayesian Alternatives from above to almost 500 variables. This is because a 106GB random matrix has to be generated at each iteration in a Gibbs Sampler.– Reduced the dimension by introducing Bayesian factor models to the already existing alternatives and implemented them.– Complete work published in the International Journal of Statistics and Probability: https://ccsenet.org/journal/index.php/ijsp/article/view/0/44345 -
Teaching AssistantUc Santa Barbara Aug 2015 - Jun 2019Goleta, California, United States• Customized tutorials for students to learn Python and SAS.• Facilitated discussions between students on the Piazza forum and in person.• Graded exams and assignments. -
