Valencia, Es

Responsibilities:- I coordinated a team of 6 people to complete more than 5 commercial products based on automatic data processing and the use of artificial intelligence models.- I designed and coordinated the development of a system to obtain data from public and private sources to obtain useful information for our clients. This development used different techniques: APIs, file processing and web scrapping.- I built a common knowledge base for the team to share resources and train easily. I also created various tutorials and customised training plans that supported the skills of each member.Technologies:- Programming: Python, Linux bash (CLI).- Other technologies: Docker, WSL, ChatGPT.- Libraries: pandas, numpy, pydantic, aiohttp, asyncio, pytest, geojson.

Responsibilities:- I collaborated in improving scalable data scrapping processes with CI/CD methodology. I developed data integrations of APIs (INE, AENA, ADIF, etc.) for the Malaga digital twin project (GeDIA).- I developed a system to change the projection of the coordinates of files with geospatial data (shapefile and geojson).Technologies:- Programming: Python, bash Linux (CLI).- Data management: SurrealDB (similar to MongoDB).- Libraries: pandas, pydantic, fastapi, requests, aiohttp, pytest, click, geojson, syncmodels, agptools.

Responsibilities:- I collaborated directly with B2B and B2C clients in sectors such as pharmaceuticals, healthcare, telecommunications, marketing and biotech, following SCRUM to meet their business needs.- Designed a continuous learning cloud system for predictive time series models using daily big data. Achieved <10% error in production with <1 year of data. Deployed with containers and Google Cloud Run, storing predictions in Google Big Query. Tested SARIMAX, GARCH, Facebook Prophet and LinkedIn Silverkite models.- Worked with Atresmedia to identify key success characteristics of their campaigns and improve advertiser results. I used unsupervised clustering with k-means and explanatory machine learning models.- I designed and implemented automated data ingestion and transformation (ETL) flows to adapt them to the needs of each project.- I collected additional data through web scraping.- I created interactive dashboards with business relevant KPIs.Technologies:- Programming: Python.- Visualisation: Python, Power BI (DAX), Mode.- Data management: Google Big Query, MySQL, SQL Server, SQL Developer, M (Power Query), QlikView.- Cloud environments: Google Cloud Platform (Cloud Run, Artifact Registry), Power BI Service, Oracle Cloud.- Libraries: pandas, numpy, matplotlib, seaborn, plotly, scikit-learn, beautifulsoup, requests, flask, sarimax, pmdarima, arch, statsmodels, greykite, datetime, pycountry.

Responsibilities:- I created an automated flow for the collection and cleaning of open source data.- I applied data mining (clustering) techniques such as Kmeans, DBSCAN and k-nearest neighbours (KNN).- I developed predictive machine learning models in Spark and PySpark using AWS.Technologies:- Programming: Python.- Cloud environments: AWS (S3, Lambda).- Libraries: pandas, numpy, sklearn, plotly and pyspark.

Responsibilities:- I designed, collected data and analysed surveys for a project on air pollution.- I enriched the data with open sources and performed feature engineering for their use.- I created generalised linear models (GLM) and ANOVA statistical models.- I developed a web application in R using Shiny, with graphs and interactive map showing geospatial data from surveys.Technologies:- Programming and visualisation: R.- Libraries: ggplot2, leaflet, shiny, maps, mapdata, dplyr, stringr, ggrepel and DT.- Models: generalised linear models (GLM) and ANOVA.
