ETL data pipeline for Data Quality, Data profiling and Data transformation using pyspark for data ingestion from multiple data sources like blob , s3 along with some data transformation and profiling rules. The processed data is then saved into the target layer which is Azure SQL.
Responsible for handling a team of 10-15 developers with multiple engagements of projects running in parallel along with ability to track daily project status on scrum agile approach
Involved in handling and solving technical problems of team by identifying roadblocks at hand at any stage of the project during POC, Dev, UAT or production and involving scaling up team resources so as to ensure smooth execution of project
Build Nifi pipeline optimization for large dataset ingestion (structured and unstructured) along with implementation of sequential job processing, Heap usage monitoring, database connection string auto-update with each job trigger
Building end to end big data ETL pipelines using Apache Nifi for creating data flows including Data Sourcing/ingestion for structured and unstructured data from AZURE BLOB storage ADLS Gen2.
Developing data flows for implementing data validation, data profiling along with data transformation rules integrated into Nifi flows invoked by front end once job is triggered.
Setup and implementation of pyspark script (for validation, profiling and transformation rules) using Apache spark 3.1 and integration of pyspark script via Nifi.
Implementation of Microservices API architecture using Django with seggregated architecture of Backend and Frontend for Master Data Management.
- June 2019 - January 2021 - 20 Months
It is a micro service based API. It is a developed to result a machine learning prediction from running python script as Lambda function and fetching data from bucket and final result of prediction is returned as a value from API endpoint
Handled the nested JSON structure of raw data and flattened it to consumable format to perform pyspark transformation.
Created workflow to automate the process of moving the incremental data from AWS S3 to redshift on an hourly basis using AWS Glue. Used job bookmarks and staging concept to populate incremental data in the existing table.
Using AWS Step function to orchestrate the workflow and scheduling it through AWS EventBridge.
Worked in agile methodology to define business goals into multiple sprints module and delivering each section of the requirement on sprint end basis.
