Excellent Incident management, troubleshooting and problem solving skills. o Perform the management of both reactive root-cause analysis (RCA) and proactive trend analysis. o Analysis and reporting of incident trend data to identify and eliminate root causes. o Keep track of operational metrics: Incident Count, Mean Time to Resolution (MTTR), Time to Acknowledgement / Time to Response, Escalations. o ELK stack (Elasticsearch, Logstash, and Kibana) : all logs aggregated into one place, no need to log into different servers to debug. o Configuration/Deployment Management tools: Ansible, Puppet, Glu o CI/CB: Git, Gerrit, Maven, Ant, Jenkins o Automated website functional sanities with Jenkins, Selenium and python. o Real time monitoring with StatsD, Graphite, Cubism, JMXTrans, Grafana. o Infra/User Experience Monitoring with Zabbix, Nagios, Zenoss, KaaE, PingDom. o WebPageTest API integration with Jenkins to perform seamless site performance tests. o Deployed custom production tools using Shell, Python and CGI scripting. • Build systems that tolerate failure - User experience is not meaningfully degraded when things fail. • Create Proof of Concept/Prototypes in order to evaluate new technologies, proactively contribute to infrastructure platform. • Traffic management: BIG-IP F5 LTM/GTM load balancing/HA. Split traffic between DC based on different routing policies. Geo-Location based traffic management using DNS policies, F5 iRule to split user/bot traffic. • AWS Services : EC2, ELB, route 53, CloudFront CDN, S3, RDS, VPC, Security group, IAM, Cloud Watch • Manage different traffic sources : SEM, SEO, Direct NAV, Affiliate, Banners • Capacity planning: Assess application performance & determining hardware capacity requirements. • Lead daily operation & Incident review meeting. • Analyze business metrics (Conv/RPV) during every production deployment. • Managing team of 20+ skilled NOC, SRE and DevOps.
