- Replatformed legacy Django modules into high-cohesion libraries with shared auth, validation, and utils across services.
- Managed Kafka producers/consumers (Schema Registry, Dead Letter Queues), processing over 1M messages/day; implemented retry patterns and DLQ metrics.
- Integrated Elasticsearch (ELK stack) and Redis as low-latency search & caching backends; implemented RedisBloom for predictions & scoring.
- Containerized all workloads with Docker; deployed on OpenShift using Helm + GitOps pipeline via ArgoCD and monitored via New Relic + custom Grafana dashboards.
- Led initiative for Shift-left testing strategy with contract tests, mutation testing (Pitest), and E2E testing with Cypress in CI pipelines.
