Responsibilities\n\nCore duties held during this position.\n\n- Architect and operate cloud infrastructure (AWS, GCP), define IaC strategies with Terraform/Pulumi, manage multi-environment deployments, and enforce cost governance\n- Provision and configure cloud environments, VPC networking, IAM roles, managed services setup, DNS configuration, and SSL/TLS certificate management\n- Govern cloud resource utilization, implement tagging policies, cost anomaly detection, right-sizing recommendations, and reserved instance strategies across environments\n- Own the full cloud stack, compute orchestration (ECS, EKS, Lambda), managed databases (RDS, DynamoDB), CDN configuration, and platform-level monitoring and alerting\n- Evaluate cloud solutions through hands-on PoCs, benchmark latency, throughput, cost per transaction, and operational complexity before production adoption\n- Make cloud provider and service selection decisions, evaluate multi-cloud vs single-cloud tradeoffs, assess managed service maturity, and define vendor lock-in mitigation strategies\n- Define cloud security posture, IAM policies, network segmentation (VPC, security groups), secrets management (Vault, AWS Secrets Manager), and zero-trust architecture principles\n- Resolve operational and security incidents, incident classification, containment procedures, forensic analysis, and implementation of preventive controls\n- Author and maintain infrastructure-as-code documentation, architecture decision records (ADRs), runbooks, and system topology diagrams for all production environments\n- Design and execute cloud migration strategies, lift-and-shift, re-platforming, and re-architecting legacy systems into cloud-native services with minimal downtime\n\n## Key Contributions & Achievements\n\nInitiatives I personally led, co-led, or was directly accountable for.\n\n- Executed a full-scale infrastructure migration to AWS, provisioning multi-AZ deployments with automated failover and disaster recovery capabilities\n- Achieved maximum cost optimization through reserved instance planning, right-sizing analysis, spot instance strategies, and unused resource elimination\n- Maximized infrastructure resource utilization by implementing auto-scaling policies, load balancing configurations, and capacity forecasting models\n- Designed and deployed comprehensive CloudWatch dashboards with granular visibility into compute, storage, network, and application-level metrics\n- Established 24/7 infrastructure observability through automated monitoring, log aggregation, and anomaly detection pipelines\n- Engineered custom alerting frameworks with multi-threshold alarms, escalation policies, and real-time notification channels for critical infrastructure metrics and usage patterns\n\n## Skills Stack\n\nCompetencies applied during this role.\n\n- ### Project Management\n\n  22 years of experience\n- ### Cloud Infrastructure
