Cloud Systems Administrator at LOi
As Cloud Systems Administrator, I managed, monitored, and continuously optimized LOi's entire cloud infrastructure — balancing computational capacity, storage throughput, and network performance against cost efficiency constraints. Architected scalable, fault-tolerant infrastructure solutions while maintaining observability through custom dashboards and automated alerting. Evaluated and integrated emerging cloud services, engaging directly with service providers and technology partners to ensure alignment with evolving business requirements.
Duties & Responsibilities
Core duties held during this position.
- Architect and operate cloud infrastructure (AWS, GCP) — define IaC strategies with Terraform/Pulumi, manage multi-environment deployments, and enforce cost governance
- Provision and configure cloud environments — VPC networking, IAM roles, managed services setup, DNS configuration, and SSL/TLS certificate management
- Govern cloud resource utilization — implement tagging policies, cost anomaly detection, right-sizing recommendations, and reserved instance strategies across environments
- Own the full cloud stack — compute orchestration (ECS, EKS, Lambda), managed databases (RDS, DynamoDB), CDN configuration, and platform-level monitoring and alerting
- Evaluate cloud solutions through hands-on PoCs — benchmark latency, throughput, cost per transaction, and operational complexity before production adoption
- 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
- Define cloud security posture — IAM policies, network segmentation (VPC, security groups), secrets management (Vault, AWS Secrets Manager), and zero-trust architecture principles
- Resolve operational and security incidents — incident classification, containment procedures, forensic analysis, and implementation of preventive controls
- Author and maintain infrastructure-as-code documentation, architecture decision records (ADRs), runbooks, and system topology diagrams for all production environments
- Design and execute cloud migration strategies — lift-and-shift, re-platforming, and re-architecting legacy systems into cloud-native services with minimal downtime
Key Contributions & Achievements
Initiatives I personally led, co-led, or was directly accountable for.
- Executed a full-scale infrastructure migration to AWS, provisioning multi-AZ deployments with automated failover and disaster recovery capabilities
- Achieved maximum cost optimization through reserved instance planning, right-sizing analysis, spot instance strategies, and unused resource elimination
- Maximized infrastructure resource utilization by implementing auto-scaling policies, load balancing configurations, and capacity forecasting models
- Designed and deployed comprehensive CloudWatch dashboards with granular visibility into compute, storage, network, and application-level metrics
- Established 24/7 infrastructure observability through automated monitoring, log aggregation, and anomaly detection pipelines
- Engineered custom alerting frameworks with multi-threshold alarms, escalation policies, and real-time notification channels for critical infrastructure metrics and usage patterns
