• Optimize prompts and workflows for batch processing, personalization, and segmentation at scale
• Manage rate limits, failover strategies, and cost optimization across AI providers
• Databases & Data Infrastructure
• Manage MySQL, Redis, and MongoDB in production environments
• Oversee bulk writes, caching strategies, event streams, and analytics pipelines
• Ensure data consistency and performance across distributed services
• Infrastructure, Reliability & Monitoring
• Own Linux-based infrastructure, CI/CD pipelines, and service deployments
• Implement centralized logging, monitoring, alerting, and uptime tracking
• Proactively identify and mitigate reliability and scalability risks
• API Integrations & System Resilience
• Manage 25+ third-party API integrations used in production
• Design retry, fallback, and graceful degradation strategies
• Ensure system stability when external providers fail or degrade
