Background

About Avinash V.

With over 13+ years of experience as a Big Data and ETL Lead, I have built a career on delivering innovative, end-to-end data solutions that empower global organizations in the banking and retail sectors. My expertise lies in architecting and implementing robust data lakes, data warehousing systems, and business intelligence projects, leveraging cutting-edge tools like Teradata and cloud-based Big Data platforms. I bring a deep understanding of relational database systems, including Oracle, Teradata, PostgreSQL, MySQL, Ataccama RDM, and Collibra, and am highly proficient in the Big Data ecosystem. My hands-on experience with Hive, SparkSQL, PySpark, Sqoop, Kafka, Flume, and Python has enabled me to design efficient ETL pipelines, optimize SQL queries, and fine-tune performance across platforms such as Teradata, Microsoft SQL Server, and PostgreSQL. Adept at data warehousing concepts like star and snowflake schemas, I excel at creating logical and physical data models that align with business objectives. I have successfully managed all phases of the project lifecycle—from requirements gathering and analysis to development, testing, implementation, and support—using both Agile and waterfall methodologies. Beyond technical expertise, I am passionate about mentoring team members, fostering collaboration, and driving consensus as a dedicated team player. I am eager to bring my skills and experience to a forward-thinking organization, where I can contribute to delivering impactful data solutions that drive business growth and innovation.
