Chandrashekar Balakrishnan

Role Senior Data Engineer.

Profile Highly motivated Senior Data Engineer with 19 years of experience across Data Engineering, Business Intelligence, Data Warehousing, Informatica MDM, and Oracle PL/SQL, including 4 years of hands on cloud experience across Cloudera CDP and Azure.

My expertise spans the design and delivery of scalable, high quality data solutions for complex enterprise environments. At Proximus, I worked extensively on the Cloudera platform, engineering large scale distributed pipelines using PySpark, HDFS, Hive/Impala, Ranger, and Apache Atlas. This experience strengthened my capabilities in big data processing, security, governance, metadata management, and high volume ingestion for both batch and near real time workloads.

I specialise in end to end ingestion and transformation pipelines integrating internal systems and third party REST APIs. I have strong hands on skills in Python, PySpark, Kafka, Flink, and Hive, delivering both streaming and batch solutions. My BI background allows me to translate business requirements into robust data models, semantic layers, reports, and analytical datasets.

I bring deep experience in Oracle PL/SQL, Informatica PowerCenter, and Informatica MDM, covering identity resolution, data standardisation, cleansing, and integration patterns. As a senior engineer, I collaborate closely with business, architects, and analytics teams to design secure, governed, high performance data platforms that deliver measurable business value.
