Key Strengths
- Built and maintained payment/booking backend APIs in Django within a microservices architecture
- Reliability engineering for payments: strict timeouts, retries with backoff, and idempotent APIs to prevent double charges
- Production monitoring/observability with metrics, custom logging, dashboards, and PagerDuty alerting
- AWS delivery using ECS + Lambda event-driven architecture (SQS/Kafka), with CloudFormation IaC and GitHub Actions CI/CD
- Cost optimization on AWS via alarms on spend spikes, right-sizing, concurrency limits, and bounded autoscaling
- ETL ownership with AWS Glue (crawlers/jobs), schema evolution handling, and data quality checks
- Modernized monolith logic into smaller services using parallel runs and gradual traffic cutover with rollback
- SQL performance tuning: reduced a booking history query from ~2s to <300ms via composite index and query rewrite
- Incident response for batch processing: detected via CloudWatch, halted payouts to prevent impact, fixed transform, backfilled, and added schema checks
