I build fault-tolerant and self-healing platforms which are easy to use, learn, deploy and contribute to and operate.

• Builds Kubernetes environment to replace existing AWS ECS clusters.
• Designs and implements API Gateway based on Envoy/Gloo.
• Creates developer experience first pipeline in ArgoCD to simplify delivery from end to end.

I build fault-tolerant and self-healing platforms which are easy to use, learn, deploy and contribute to and operate.

• Take ownership of the core infrastructure and platform that Domain runs on
• Designs and builds Kubernetes-based platform and workflow to support business requirements.
• Creates building block to shift left security (Orca, CrowdStrike), qualify (SonarQube) and observability (ELK) into the platform and pipeline.
• Delivers capability uplifting into product teams, and then establish sufficient documentation to allow teams to self-serve.
• Uplifts and improves CI/CD and developer experience in Jenkins/Github Action/ArgoCD, migrates teams into GitOps workflow.

I optimized, improved and maintained hybrid Heroku/AWS application environments.

• Developed subject-matter expertise on Cloudflare by understanding stakeholder needs and views.
• Containerized Continuous Delivery pipelines for a suite of Ruby and NodeJS applications.
• Assisted with our team's building out all infrastructure in managed code using Terraform.
• Collaborated with peers on the development of new tools and services used by all engineers.
• Integrated and migrated monitoring solutions into meaningful observability measurement, to help stakeholders in decision making.
• Added customized instrumentations to code for adding application observability.

I leaded the project to containerize EC2-based environment for better avaliability.

• Built new NGINX(EC2)/PHP/Laravel(EC2)/MySQL(RDS) systems in AWS from code repository to fully automated test/staging/prod environment
• Implemented packer pipeline to build immutable AMI and update AutoScaling Groups, utilizing CodeDeploy to provide blue/green deployments.
• Rebuilt build/deploy pipeline to improve mean time to deliver from 2 hours to 10 minutes.
• Migrated CloudWatch Logs to SumoLogic and built SumoLogic log/metrics-based dashboards to provide operation and business visibility.
• Worked with security team to obtain SOC 2 Type 2/ISO 27001.
• Reduced AWS Cost by 10% in 6 months and improved efficiency.

I built new infrastructure-as-code .Net-based systems in AWS, deployed by CI/CD pipeline with Azure DevOps/Octopus Deploy/Atlantis/Terraform.

• Provided end-to-end performance visualization and real-time security issue identification in the production environment via SumoLogic/Site24x7/PRTG/Cloudwatch and reduced the response time from 45 min to 15 min.
• Implemented AWS automation to cut down the production update window by 50% and eliminate human dependencies by 90%.
• Converted existing manual deployments to reproducible idempotent processes in the CD pipeline.
• Performed vulnerability scans again internal system at a different level with different tools: Cloud Conformity/Rapid 7/Amazon Inspector and applied report with remediation.
• Planned, migrated and managed On-Premises Atlassian stack to Atlassian Cloud.
• Connected Okta SAML/SSO with all internal/external services.

I supported day-to-day operations of the company and all the customers by proactively identifying problems and analyzing future needs.

• Performed all systems administration duties, including configuration and maintenance of business services on both Windows and Linux-based, physical and VMware environments.
• Automatic provisioning of enterprise infrastructure and application environment through Gitlab, Terraform, Ansible and PowerShell in multi-stack instances.
• Managed and validated auto-restored backups with PowerShell scripting.
• Designed and implemented High Available AWS solutions for clients with Auto Scale EC2, ELB, Amazon RDS and S3.

I managed over 1200 RHEL virtual machines on VMware vSphere infrastructure of more than 250 servers located in three different data centres.

• Dedicated project manager with responsibility for Linux automation platform deployment, leading a team of five technical people.
• Provided Level 2 and Level 3 support for business-critical systems.
• Planned a disaster recovery strategy with the standard of three data centres.
• Analyzed multi-dimensional system issues including performance tuning, kernel panic trouble-shooting, application trouble-shooting, resource allocating, and system security enhancement.

I was responsible for management, strategy and execution of IT infrastructure in Talend Beijing Office.

• Administrated over 300 Centos/Ubuntu mixed virtual machines on VMware vSphere infrastructure of more than 20 servers.
• Participated in testing and operating OTRS IT management system, providing improved customer SLA for internal staff with supporting and tracking.
• Experienced in agile development and configuration management technologies such as Kickstarts, Cobbler and Ansible.
• Managed and maintained VMware vSphere clusters.

Solo engineer managed all Linux servers and IT environment.
