Data ScientistPragmaMar 2022 - Current (3 years 5 months)Implemented several neural networks architectures (convolutional and recurrents) for detection, segmentation and extracting text from receipt recognition. So that automatization over huge amounts of images can be feasible. ●Collaborated in the development of a ML platform using diferentes services from AWS to detect objects in a videos uploaded by the user. So that, user can make queries about a particular object if it appears in the video. ●Designed and Implemented algorithms to segment customers in order to increase customer lifetime value (CLV) KPI. ●Used Data Mining algorithms to process comments of customers, which were obtained after AWS Transcribe converted audio into text. This way, we could identify some patterns and correlatio- Data ScientistNTT DataSep 2021 - Jan 2022 (5 months)- Collaborated in the development of forecasting models to predict the number of products sold. Where an average mAPE of 10% was achieved in all 40 stores. - We proposed human resources optimization models for each of our client's stores, achieving a payback of the project cost in less than 5 months. - Exploration of Data Analysis on datasets of 40 million records using the Big Query API, standard SQL, and store procedures.
- CResearch Data ScientistConcytec PerúSep 2020 - Jan 2022 (1 year 5 months)- Proposed a new data structure based on trees in the state of art, that allows interactive similarity queries (Real-Time) of large volumes of georeferenced and mixed multidimensional (30+ numerical and categorical attributes). - Implemented visualization prototypes that include the backend (c++) and frontend (javascript), allowing us the exploratory analysis of the data stored in the data structures, exploiting the capabilities of similarity queries.
