IndiaWhat I'm looking for
I am a results-driven Big Data engineer with around 7 years of experience delivering scalable ETL solutions using Spark, Scala, PySpark, Hadoop ecosystem tools and cloud services like AWS and Snowflake. I have led migrations (Databricks→EMR Serverless, Redshift→Snowflake), optimized job performance and costs, and automated data workflows using Airflow, Oozie and Control-M.
I collaborate closely with product owners, onboard and mentor trainees, and build monitoring dashboards (ElasticSearch/Kibana) to replace manual operations. My work emphasizes data reliability, performance tuning, and pragmatic automation to accelerate analytics and business outcomes.
