About Karthik Polisetty

13+ year veteran specializing in Cloud Data Architecture, Analytics Engineering, and enterprise-scale Platform Modernization. I transform complex data into strategic business value, driving measurable efficiency and informed decision-making across complex, regulated sectors like Aviation, Finance, and Telecom. Core Expertise & Business Impact:BI & Analytics Strategy: Led high-impact BI transformations, spearheading the migration of legacy reporting platforms (OBIEE, Cognos, Hyperion) to modern visual tools (Power BI, Tableau, MicroStrategy). This work resulted in a 60% reduction in report generation time and a 55% optimization of Power BI data refresh times through DAX and incremental refresh techniques. Data Architecture & Cloud Engineering: Deep expertise in designing and deploying Data Lakehouse Architectures (using Azure Databricks, Synapse Analytics, and Microsoft Fabric POCs). This includes large-scale ETL/ELT pipeline orchestration (Azure Data Factory, Informatica, DataStage) and leveraging high-performance languages (Python, PySpark, T-SQL). Demonstrated capability in multi-cloud data integration, including working with AWS S3 and configuring solutions on Azure/GCP infrastructure. Data Warehousing & ETL: Proficient in managing complex data ecosystems, with hands-on experience integrating and modeling data across major databases including Oracle, Teradata, Netezza, SAP HANA, Snowflake, Redshift, and SQL Server environments, underpinned by strong UNIX scripting and PL/SQL skills. Strategic and Value Focused: Highly adept at Stakeholder Management and translating requirements into technical frameworks. For example, implementing Row-Level Security (RLS) in Power BI,MicroStrategy drove a 25% improvement in personalized sales revenue. AI/ML Readiness: Actively focusing on the next frontier of data solutions. Leveraging Generative AI Fundamentals certification to align data governance and pipeline infrastructure for future MLOps and predictive analytics initiatives. I am passionate about building robust technical solutions that ensure data quality, scalability, and measurable business outcomes.
