Hiring Manager
Tata Consultancy Services
Dear Hiring Manager,
Building reliable data pipelines that power decision-making at scale is what excites me about data engineering. In my current role at Forage AI, I migrated our ETL workflows from Azure Data Factory to AWS Glue, reducing pipeline runtimes by 40% and improving our analytics SLAs. Tata Consultancy Services' diverse client portfolio presents the kind of complexity I thrive on solving.
I lead a team that designs microservices serving over 1 million requests per day, and we recently improved test coverage across the CI/CD pipeline to catch regressions earlier. Technologies like Spark, Scala, and Kafka are part of my daily toolkit, and I appreciate how Tata Consultancy Services leverages cloud-native architecture patterns to deliver value for customers.
Before Forage AI, I spent three years as an ETL Developer at ValueMomentum, where I automated data quality checks and reduced QA cycle times by 50%. I am comfortable collaborating with analysts, data scientists, and business stakeholders to ensure that our pipelines underpin trustworthy insights.
