I’m coming back from a sabbatical & virtual volunteering year at ReDI School of Digital Integration in India as a Python tutor where I did data research projects using Pandas, SQL, Numpy, and Power BI. Before that, I worked in Paris at Operanka Associates, Paris, France Project: Operanka Associates is a Paris-based FinTech startup delivering financial data analysis & artificial intelligence services to banks like HSBC, BNP Paribas & Société Générale. I worked in a data team of 6 creating, cleaning, and preparing client datasets using Python, SQL, Pandas, Numpy, Tableau, and Power Bi. Analyzed a data set of 50k+ customer questions to improve customer satisfaction metrics and created various dashboards using Power BI. Developed solutions by web scraping using Python to extract data e.g. the texts, links of websites, and relevant documents of data protection regulations from the internet. This reduces the effort for manual data extraction by 90%. Automated the process of information extraction of EU data protection regulation text by 2 to 3 hours instead of manual google search of files. Developed a chatbot using NLP. Improved the confidence level of intents and entities from 40% to 80% by creating co-occurrences of certain entities which involved handling lists, and string data types. Tech used: Python | SQL | Pandas | Numpy | Power Bi | R | NLP | Data Analysis | NLP Web Scraping | Jupyter Notebook | Linux | Data Cleaning | Data Preparation.

Project: Wegravit a Lille-based startup that created a social media engine without leveraging advertisements and not utilizing user data to make profits. I worked in a Data Analyst team of 3 developing a filtering algorithm to recommend and match users to other users according to the specific keywords (e.g. similar hobbies, same University, work domain, etc.) on the social media platform using R, Python, SQL, and recommendation techniques. This helped users find the right connections to socialize. Designed a transportation and navigation application (as part of a competition by the SNCF train company) to assemble all kinds of transport (accessing real-time traffic data of metro, tram, bus, and cycle of the city of Lille) within one single application along with other added features using tools like R, Python, JavaScript, and PHP. Tech used: R | SQL | Python | Recommendation systems | Javascript | PHP | Data Analysis | Pandas | ggmap | ggplot2.
