DevOps Engineer - Independent

---

Role Overview

Delivered independent, production-facing DevOps engineering work focused on real-world cloud-native system design and operations.

Responsibilities & Work

• Led independent, self-initiated engineering work, designing and operating production-grade DevSecOps and GitOps platforms on AWS and Kubernetes
• Architected end-to-end CI/CD pipelines integrating Maven, SonarQube, Trivy, Snyk, SBOM generation, Cosign image signing and artifact publishing to Nexus and AWS ECR
• Designed and validated multi-environment GitOps workflows using Helm and ArgoCD, with GitHub Actions automating application promotion across dev, stage and prod-like environments
• Built and automated secure static web application delivery on Amazon S3, including CI/CD pipelines and authentication-based access controls
• Implemented service mesh–based traffic management and observability using Istio and the Kubernetes Gateway API with mTLS, integrating Prometheus, Grafana, Jaeger and Kiali
• Maintained fully documented, reproducible infrastructure and delivery pipelines in public GitHub repositories to demonstrate repeatability and real-world DevOps workflows

Key Learnings

• Designing CI/CD pipelines as control systems, not just build automation
• Using GitOps to improve operational correctness, auditability and rollback safety
• Managing security by reducing blast radius through externalized secrets and IAM-based access

Role Overview

Designed, operated, and stabilized containerized delivery platforms on AWS, owning CI/CD pipelines, Kubernetes workloads, GitOps delivery and production incident resolution across multiple environments

Responsibilities & Ownership

• Built and ran CI/CD pipelines with Jenkins and GitHub Actions, integrating Maven, SonarQube, Trivy, Nexus and Amazon ECR
• Operated AWS EKS workloads using Helm and Argo CD with GitOps and blue/green deployments across environments
• Provisioned and managed AWS infrastructure using Terraform, including EC2, IAM and VPC networking
• Managed Kubernetes deployments, handling rollouts, configuration updates, scaling and rollbacks
• Handled production incidents involving networking, load balancers, firewalls and resource exhaustion with RCA
• Implemented monitoring and dashboards using Prometheus and Grafana to improve visibility and issue detection

Key Learnings

• Operating Kubernetes in production requires disciplined resource management, rollout control and failure isolation
• GitOps enforces auditable, repeatable deployments, but only works when pipelines and manifests are production-hardened
• CI/CD systems are critical infrastructure, not developer conveniences
• Observability must drive incident response, not just dashboards
• Most outages are caused by misconfiguration and resource pressure, not code

Role Overview

Owned and operated AWS-based production infrastructure supporting EC2-hosted applications, with direct responsibility for availability, scaling, monitoring and deployment reliability across development and production environments

Responsibilities & Ownership

• Managed AWS production infrastructure using EC2, VPC, RDS, Auto Scaling Groups, ELB, S3, Route 53 and EBS, ensuring high availability and operational stability
• Refactored static EC2 deployments into Auto Scaling Groups with Load Balancers and health checks, improving fault tolerance and recovery during instance failures
• Implemented snapshot-based EBS backups and proactively expanded storage capacity to prevent disk-related outages
• Designed and maintained secure VPC architectures with public/private subnets, route tables, internet/NAT gateways, NACLs and security groups
• Built and tuned CloudWatch dashboards and alarms based on real production failure patterns, reducing time-to-detect and response during incidents
• Managed Route 53 DNS changes during deployments and production incidents to minimize service disruption
• Built and maintained CI/CD pipelines using Jenkins, Git, and Maven, handling pipeline configuration, plugin management and environment-level failures

Key Learnings

• Designing EC2-based architectures for high availability and resilience under failure conditions
• Using Auto Scaling and Load Balancing to handle traffic spikes and instance failures gracefully
• Building monitoring that reflects real operational risk, not vanity metrics
• Operating CI/CD systems as production infrastructure, not just build scripts

Role Overview

Worked as a Backend Engineer developing and operating web applications in Linux-based production environments, owning feature delivery, application deployments, external service integrations and runtime stability

Responsibilities & Ownership

• Developed and enhanced backend features to support core business workflows, including integrations with external payment and shipping services
• Designed and maintained REST-based server-side services, ensuring reliable data processing and system performance
• Provided production support, troubleshooting application issues, deployment failures, and performance degradation to maintain service availability
• Handled domain configuration and basic DNS management, ensuring correct routing and minimal service disruption

Key Learnings

• Backend development extends beyond coding — deployment, configuration, and runtime stability directly impact user experience
• Production issues are often caused by environment, configuration, or dependency failures, not just application defects
