optimization for building very efficient and scalable data systems. • Excellent SQL programming skills. • Excellent problem solving skills. • Excellent communication skills with both business and technical customers. • Demonstrate a high level of integrity and maturity. • Work on multiple projects and deliver consistently on time. • Escalate issues appropriately to management and project team. • Take a proactive approach to cross-functional communication. • Actively seek out feedback from management and peers, to improve own performance based on that feedback
Roles & Responsibilities • Interacting with Business Users/ Business Relationship Managers to understand the BI and analytical needs • Identify the right data sources / data completeness to meet the BI needs. • Data profiling to build the entity relationships across multiple sources. • Develop and maintain data dictionary for all the data sources (existing and new ones). • Build conceptual and logical data models considering the BI needs. • Develop optimized database design to achieve acceptable performance by tuning views, tables for proper response time. • Work with database administrators to implement data models into database platforms, ensuring data integrity
and consistency. • Monitor database performance, identify bottlenecks, and optimize data models to improve query efficiency and
data access speed. • Work closely with the IT teams in ETL design discussions adopting best practices of data load strategy. • Identify effective reporting techniques, identify the best data sources for each report, identify risks and constraints,
and design reporting formats. • Create and maintain metadata describing the data model, including data lineage and definitions. • Data analyst skills to determine root cause problems for data integrity and data quality issues identified through QA
or by business report owners. • Define data storage strategy
