Joined Big Data Practice Team
-
Part of COE bigdata practice team where get aligned to multiple projects for Installation, configuration, enable security on multiple bigdata tools.
Involved in multiple RFP and POC activities.
Automated so many Project based tasks by using python.
-
- I have integrated R Studio Tool with HDFS and Actian VH databases.
- I also have integrated Pentaho Tool with HDFS and Actian VH databases.
- I also used pyspark as an ETL.
- I also used Apache Airflow for creating python jobs and scheduling the jobs.
- I also created a python program for the detecting and correcting(or removing) corrupt or inaccurate records from a record set, table, or database.
- I wrote python program for the schedule and monitor data pipelines in Apache Airflow.
-
- I worked on Actian VH integration with Hadoop cluster and analyzed the Actian VH performance as comparison with respect to Hive and Impala.
- I worked on BuyWay RFP with my team and contribute some solutions from my side.
- I also suggested the Hadoop platform architecture for State Govt. of Texas Project.
- I did Migration of databases from On-Premise to Google Cloud Platfrom BigQuery Data Warehouse.
-
Cross-cluster search: Implemented ELK (Elastic Search, Log stash, Kibana) stack to filter and analyze log data stored on clusters in different data centers.
Data Profiling: In this activity, I had raw data which contained unwanted value like null, Junk value, missing values and duplicate values. For improving the data quality, I removed all the unwanted values by using SparkSQL and made it suitable for visualization.
Migrate On-premise database to GCP Big Query : In this activity, I took the backup of required databases and converted all backup files into csv file format by using python script then transferred to Google cloud Storage after that using bq load, pushed all data in Big Query Datawarehouse. And I did Oracle Databases migartion to BigQuery by using Informatica Intelligence Cloud Services.

Spark Structured Streaming with Kafka :In this activity, I had 3 nodes Kafka Cluster, 1 node dedicated for Zookeeper and Installed standalone Spark and Hadoop for data processing and Storage the processed data. I got real-time data from weather website by using API and created Kafka Producer to ingest the weather data to Kafka topic. Then I used structured streaming for processing data and stored into HDFS. For the Visualization, I have used Kibana.
Spark Structured Streaming with Kafka :This activity I have done for one of the cab service provider industry. In this activity, I had a python application which generated the cab drivers related information’s in real-time. I have created custom Kafka Producer and using Structured streaming, processed the data for checking the driver’s availability like total numbers cab drivers, how many drivers are on duty etc.
