• Designed and built internal Executive Dashboard using perl, php, mysql, jquery and bash scripts. Functions as Executive real-time and historical view of key metrics for the business: orders per minute, sales, uptime vs. SLA, production issues, orders by device type and batch processing run-times to name a few. Received the company’s “Blue Moon” award for this.• Architected a system to monitor and alert on Amazon EC2 instances running longer than expected. Load and QA testing users were creating numerous EC2 instances, forgetting to shut them down upon completion, costing the company significant expense. This system is used for “Root Cause Analysis”.• Engineered a system using SNMP calls against the company’s many Big-Ip’s to monitor traffic (inbound, outbound and active connections). With the company running numerous stores, spotting “Denial of Service Attacks” by looking at overall traffic is challenging. This system solves that problem by monitoring individual stores and alerting on high traffic patterns.• Designed and built a system to report on mobile device usage, categorized by store. This provides the company visibility into which stores have the highest utilization of mobile devices and how to best deploy mobile development efforts.• Created a business metric monitoring system that tracks critical company metrics. This system has saved the company millions of dollars in SLA penalties by proactively notifying of production issues prior to them causing system downtime. • Built a web log monitoring and alerting system that analyzes jsp response time for an average of 135 million page views per day. This monitoring system enabled the company to recognize, and quickly remediate poor performing pages.
