Build a Data Lake for a Ed-tech Startup

We have worked for an Ed-tech startup, the start-up idea is to spread knowledge to less privileged people here in Pakistan by providing lectures and solutions to there problems through application, before digging into data the team was facing low growth and unable to identify areas for improvement, here We designed and developed the whole data journey, gathering and ingesting data from multiple sources into AWS S3 buckets and then building reports and dashboards identifying key metrics and helping achieve growth and resolving problems of students.We build the whole data journey on Databricks, extracted data from files (json and flat flies), CRMs and RDBMS, transformed the data on Databricks using python and pyspark and created a data warehouse model on AWS Redshift.
