PROFILE
Pradeep Swamireddy
Worked on the govuk-one-login/data-analytics-platform repository, delivering secure QuickSight dashboard embedding with Cognito and API Gateway, and building Lambda functions for OAuth code exchange and Redshift error alerting. Refactored the ETL data processing pipeline, improving S3 partitioning, schema evolution, and NULL handling using Python and Pandas. Enhanced CI/CD reliability by hardening permissions, escaping edge-case commit messages, and centralizing Quicksight packaging workflows with GitHub Actions and YAML. Improved observability through CloudWatch alarms, SNS notifications, and Slack integration for Step Functions failures. Focused on robust data engineering, infrastructure as code, and operational visibility to support reliable analytics and secure dashboard access.

Jun 1, 2025June 2025 monthly summary for govuk-one-login/data-analytics-platform: 1) Key features delivered: - Data Processing Pipeline Refactor and Enhancements: Refactored the pipeline, updated S3 bucket naming and partitioning schemes, introduced a date manipulation utility with tests, and included a bug fix for ETL date calculations plus enhanced preprocessing to support duplicating columns. Commits: 8a2f39dd9dfa071ff27263d790bb1399226a2077 - DPT-1784 Stability and Timeout Tuning: Increased wait time for DPT-1784 operation from 5s to 120s to improve stability and prevent timeouts; adjusted a configuration parameter. Commit: 2afeb39697720e43b1a0adc8263c112bd14edf01 - Safe Schema Evolution and Ingestion Configuration for Staging: Updates Glue Crawler and Kinesis Firehose settings for staging: reduce buffer timings; configure Glue Crawler to merge new columns and log changes instead of deleting or modifying existing data, ensuring safe schema evolution. Commits: aa1101e312ea447cdd39077124da5e70686aefb0, 9c88432d4bfb358d962ed2ed43a466c78543e327 2) Major bugs fixed: - ETL date calculation bug in the Data Processing Pipeline, addressed as part of the pipeline refactor; improved correctness of date-based processing and partitioning. 3) Overall impact and accomplishments: - More reliable and scalable data ingestion with safer schema evolution in staging, reducing deployment risk. - Significantly improved pipeline stability by extending DPT wait time, lowering timeout-related failures. - Strengthened test coverage for date utilities, enabling safer future changes to date-driven logic. 4) Technologies/skills demonstrated: - Data engineering: ETL pipeline refactor, S3 naming/partitioning, Glue Crawler tuning, Kinesis Firehose configuration - Testing: date utility development and tests - Configuration/ops: timeout tuning, buffer timing adjustments - Code hygiene: meaningful commit messages and traceability
