Advanced KPI Reporting and Dashboard Redesign Powered by AWS

A home security provider sought to modernize its legacy data warehouse and business intelligence ecosystem. The objective was to design scalable SQL-driven ETL pipelines using Airflow, build data models in AWS Redshift and enhance Tableau dashboards to deliver data-driven deeper insights.

Client Challenges and Requirements

• Assess and document existing legacy data warehouse mappings and business rules.
• Build optimized fact and dimension tables for high-performance analytics.
• Design a scalable, SQL-driven data pipeline to automate ETL processes.
• Develop optimized SQL queries for ETL and BI workloads.
• Redesign and enhance dashboards to include advanced KPIs and improved visual performance.
• Implement validation rules across ETL and dashboard layers to ensure data accuracy.

Bitwise Solution

• Bitwise followed best practice and AWS cloud native purpose-built services for end-to-end data solution enhancement and redesigning to accelerate project timeline within budget requirements.
• Leveraged YAML-based framework for defining ETL job configurations like job parameter and logic. Then the framework dynamically generates python DAG for Apache Airflow, enabling easy orchestration, scalability and maintainability.
• Implemented a SQL-based approach for developing ETL jobs. Developed optimized SQL queries, Focusing on minimizing join operations, leveraging appropriate indexing strategies, to handle large volumes of data.
• Integrated data integrity checks into the YAML-based framework by defining validation rules such as schema validation, row counts, column match and data type checks.
• Identification of the business requirement and complexity of the dashboards. Build new Tableau dashboards by adopting iterative and modular approach.
• Create dynamic visualizations in Tableau using advanced metrics and KPIs, Integrate optimized SQL queries to ensure performance.
