Support Kubernetes-based deployments, containerized application environments, and blue-green deployment strategies. Contribute to CI/CD pipeline improvements using tools such as GitHub Actions, CircleCI, Jenkins, and Travis CI. Conduct peer code reviews to promote quality, maintainability, reliability, and adherence to engineering standards. Collaborate with DevOps teams to support deployment automation, monitoring, and production reliability. Implement observability, logging, alerting, and incident response support using tools such as Datadog and PagerDuty. Develop data ingestion, ETL, structured file processing, and complex validation workflows. Partner with product managers, business stakeholders, QA teams, and other engineers to understand requirements and deliver effective technical solutions. Contribute to technical discussions, architecture reviews, estimation, and sprint planning. Integrate third-party APIs such as Salesforce, HubSpot, NetSuite, OpenAI, Stripe, and Twilio. Support AI/ML-enabled features, including RAG-based search, LLM integrations, and data-driven analytics platforms.
