Experience
Data Engineer
Jul 2022 — Present · Mumbai, IN
I successfully drove data management, migrating data between frameworks using automated Python scripts, developing Snowflake procedures, and refining ETL frameworks to optimize performance. I designed and implemented Python scripts for metadata management, data cleaning, and validation, anddeveloped SQL queries for data merging. I also set up Control M jobs and Matillion orchestration jobs for efficient data processing and automation, resolving critical production issues and mentoring a team of 3. Additionally, I played a key role in implementing robust ETL/ELT processes, on boarding multiple applications, and mastering metadata-driven ingestion frameworks using Matillion. I expanded my technical expertise through hands-on experience with tools like Snowflake, Control M, ADO CI-CD pipelines, and AWS services, ensuring seamless data management and compliance that drove businessgrowth through informed decision-making.Key achievements: • Reduced failure tickets by 90% with developing auto-rerun logic for Control M jobs. • Optimized SQL queries, reducing Info Mart query runtime by 95% used in business dashboard (90 min → 6-7 min). • Improved data ingestion, reducing parquet file load time by 92%(6 hours → 30 min).
