I'm currently building a Customer Data Platform for Nedbank on AWS EMR and S3, processing transaction, demographic, and online activity data for personalized banking services. My Spark jobs, Parquet-based S3 storage, and data masking work enabled targeted campaigns that increased customer engagement and product adoption by 25%.

Previously at ABSA Group, I transformed heterogeneous source data into target-specific formats, analyzed large datasets with Hive, and migrated data from HDFS to AWS S3. I also used Spark SQL to read Parquet data and write it to Hive while working in an Agile Kanban environment.

At Infosys, I modernized enterprise ETL workloads for AWS using Glue, Lambda, Step Functions, Redshift, EMR, and S3. I translated SSIS logic into AWS Glue scripts, automated ETL orchestration, and supported planning, code reviews, testing, releases, and deployment.

I also built real-time event-streaming platforms with Hadoop, Spark, Kafka, NiFi, Hive, Kubernetes, Airflow, and Kibana. I’ve developed Kafka connectors and KStreams transformations, migrated relational data to HDFS with Sqoop, optimized Hive queries, and supported production processes.
