Professional Experience
DevOps Engineer • Callsign Technologies
- Led and mentored a team of 5 DevOps engineers responsible for managing 15+ production and non-production environments, overseeing component upgrades, releases, feature development, and continuous improvements to the infrastructure codebase.
- Maintaining 99.99% uptime while leading critical services upgrades (EKS, RDS, MSK) with zero downtime and no data loss.
- Building the product's Azure platform, developing Terraform modules for AKS, VNet, Front Door, Application Gateway, and MySQL Flexible Server to achieve parity with the established AWS production environment and enable multi-cloud deployment.
- Played a key role in emergency cross-region DR failover for a top UAE banking client during a multi-AZ AWS outage, coordinating with AWS support to migrate RDS databases, replicate S3 data, and provision complete infrastructure in the secondary region, restoring full service operation.
- Achieved $200K+ (35-40%) in cloud cost reduction through Graviton migrations, compute rightsizing, automated non-prod environment downscaling, and storage lifecycle management.
- Reduced critical CVEs through comprehensive cluster security implementation including Kyverno policy enforcement, Trivy vulnerability scanning, and automated AMI patching via Karpenter.
- Reduced deployment time by 30-40% by refactoring deployment strategy to decouple infrastructure and application releases, enabling independent and faster change rollouts.
- Cut infrastructure provisioning from hours to minutes by building a GitLab pipeline framework orchestrating 15+ Terraform repos.
- Serving as primary escalation point for complex production incidents, conducting deep-dive root cause analysis across distributed systems to identify issues spanning multiple services, clusters, and AWS components.
- Reduced deployment time by migrating from IRSA to EKS Pod Identity, simplifying IAM management across all microservices.
- Improved cluster autoscaling efficiency by migrating from AWS Auto Scaling Groups to Karpenter and implementing event-driven scaling with KEDA, reducing response time to traffic spikes.
DevOps Engineer • Dubizzle Labs
- Containerized legacy applications and migrated them to Kubernetes, delivering production-grade scalability and reliability.
- Built and rolled out GitOps workflows with ArgoCD, Helm, Kustomize, and External Secrets, ensuring consistency across production and non-prod environments.
- Designed and implemented CI/CD pipelines using GitHub Actions integrated with ArgoCD, enabling automated and reliable deployment strategy with minimal human intervention.
- Implemented a centralized observability stack with OpenSearch and Fluent Bit, reducing incident detection and troubleshooting time from hours to minutes.
- Continuously improved Terraform codebase to ensure consistent infrastructure across environments.
- Integrated AWS SSO with ArgoCD and OpenSearch, tightening access control and simplifying authentication across the platform.
DevOps Engineer • Arbisoft
- Migrated workloads from standalone EC2 instances to auto-scaling-group based architecture, improving availability and reducing operational overhead.
- Enhanced CI/CD pipelines with CircleCI and AWS CodeDeploy, accelerating release velocity and minimizing deployment failures.
- Authored reusable CloudFormation templates to standardize infrastructure provisioning and ensure consistency across projects.
- Tuned and optimized Nginx configurations, reducing application response times by more than 70%.
- Automated repetitive operational tasks with Bash scripting, increasing team efficiency and reducing manual toil.
- Integrated New Relic for application performance monitoring, enabling proactive issue detection and faster root-cause analysis.
Software Engineer • Northbay Solutions
- Worked on writing reusable IaC scripts in CloudFormation and Terraform for seamless infrastructure provisioning.
- Contributed to the design and implementation of an application migration from Rackspace to AWS ECS, improving scalability and reliability of services.
- Developed AWS Lambda functions workflow orchestration using Step Functions, automating event-driven processes.
- Set up SFTP server on AWS using AWS Transfer Service, ensuring secure and reliable data transfer.
