I am a data analyst with experience in data analysis using R, SQL, and R Shiny. I have real projects including:
Food delivery data analysis: Used Association Rules and Clustering techniques to discover factors affecting delivery delays (such as traffic, weather, and vehicle type), and built an interactive dashboard using R Shiny.
E-commerce database design: Designed a complete SQL database (8 tables, primary/foreign keys, ERD), and wrote complex queries.
I offer services in:
Data cleaning and analysis
Building interactive dashboards (R Shiny)
Extracting hidden patterns using Association Rules
Customer or project segmentation using Clustering
SQL database design
I work with precision, commit to deadlines, and maintain communication with the client until full satisfaction.
