About

Backend/data engineer with hands-on production experience building reliable Python FastAPI services on Kubernetes and delivering AWS EKS + Terraform CI/CD with strong secrets isolation and rollback practices. Also built AWS Glue ETL pipelines into S3/Redshift with schema-evolution handling and data-quality controls, modernized legacy analytics into modular Python services with parallel-run parity validation, and has demonstrated SQL tuning impact (minutes to seconds) plus ownership of batch pipeline incidents end-to-end.

Experience

Key Strengths

• Built and operated production FastAPI services on Kubernetes with PostgreSQL/Redis
• Reliability engineering: strict timeouts, exponential backoff retries, circuit-breaker behavior, idempotency-based retry decisions
• Strong observability practices (structured logging, metrics, health checks) and automated testing/CI-CD
• AWS EKS delivery with Terraform IaC and multi-environment CI/CD (dev/staging/prod) including validation and rollback
• Secrets/config management using AWS Secrets Manager with IAM and environment isolation
• AWS Glue ETL design with schema evolution via crawlers, data quality checks, and operational recovery (alerts, retries, backfills)
• Modernized legacy analytics into modular Python services with parallel-run parity validation and stakeholder sign-off
• SQL performance optimization using execution plans, composite indexes, partitioning, and batching; improved runtime from minutes to seconds
• Owned and resolved batch pipeline incident using CloudWatch alerts/log triage; added upstream validation and late-arrival alerting to prevent recurrence
