Key Strengths
- Built fraud detection pipeline for AWS Lambda processing billions of requests/day
- Designed data quality layer for inconsistent multi-region telemetry logs (schema validation, null handling, timestamp standardization, outlier filtering)
- Implemented automated schema-change checks/alerts in AWS Glue to prevent upstream breaks
- Scaled real-time processing using AWS Kinesis with parallelization and resource optimization to reduce latency
- Entity resolution across multi-source logs using standardized keys, timestamp normalization, and fuzzy matching (Levenshtein distance)
- Pragmatic ML delivery: moved from experimentation to production based on baseline performance, feature stability, and business alignment; added monitoring and CI/CD
