* AWS Cloud development and automation using Javascript and the Cloud Development Kit. I was the first member of the team to move to an Infrastructure as Code mindset and helped others learn and adopt. With the CDK I was able to design scalable systems using S3, Load-Balancers, EventBridge, Systems Manager, and RDS. I refactored multiple projects from traditional hands-on deployment strategies to deploy using the CDK and CloudFormation.* Reduced off-hours engineering work 90 hours per month by developing a solution that performs SQL Server database refreshes. This solution utilizes Jenkins and PowerShell to backup and restore databases from our production environment to our dev and test environments retaining all applicable permissions. This solution has been integral during our Cloud migration and has saved over 3000 hours of engineering time.* Refactored our monthly close process eliminating the need for manual steps and reducing monthly report generation by 7 hours. I added routines that perform pre-checks, backups, restores, and error checking when the process completes.* Managed, built, and supported our AWS RDS & Microsoft SQL Server environment. Troubleshoot performance issues, SSIS problems, and general operational support including AWS database migration services.* To increase awareness and visibility into our critical business systems I designed multiple data ingestion pipelines using Kinesis, Athena, Glue, Quicksite and ElasticSearch. This data was used to create reports, dashboards, and alerting which helped us avoid multiple outages.* Worked with developers on Jenkins related issues and helped create new pipelines when needed.

• Led and mentored Jr. engineering staff as Incident Commander on over 100 customer-impacting events.• Reduced customer notifications engagement by 95% by developing a Slack bot, which ran on AWS serverless technology, utilizing Lambda & AWS Gateway.• Created the training plan, supporting documentation, and prepared the organization's Incident Commander readiness training.

• Manage a fully remote team of developers in charge of tooling and automation for CenturyLink operations. • Manage a team of 60% remote DevOps engineers using a combination of scrum and Kanban agile practices.• Prioritize the backlog for Billing, Operations and Software Tooling. Priority is based upon key performance indicators with focus on improving the customer experience and reducing customer impacting events. • Spearhead a custom monitoring solution backed by Elasticsearch and MongoDB, identifying issues with our customer portal, network, infrastructure and supporting services. We perform analytics in real time using Kibana to identify, mitigate, or prevent customer impact. Reduced customer impacting events by 18% in the first 6 months.• Prioritize feature development on our Slack Chatops system reducing our Incident start times & SME engagement by 10 minutes. This system creates the communications channel, master ticket, and pages the Incident Commander, Communications Expert & the Executive on call. • Drove over 250 high-impact incidents to resolution on our Incident Commander on-call rotation. • Provide leadership, guidance, and mentorship to the entire engineering team. Hold engineers accountable for following process & procedure and continuously improve our documentation as tooling and efficiencies are advanced.

• Participated in bi-weekly sprint planning advocating for priorities of the team, voiced concerns over proposed solutions, task sizing, and engineer availability. • Partnered with the software tools and automation Engineering Manager to develop a more robust Agile system for handling our sprint/project work. • While on the Shift Lead on-call rotation, I was responsible for handling all customer escalations. I would engage, evaluate the issue, and recommend next steps. • Revamped, rewrote, and recorded our Incident Management procedure. This procedure is used by the entire Cloud organization for processing customer tickets, infrastructure alerts, and customer outage scenarios. • Wrote the Incident Commander (IC) process & procedure documentation, reducing root cause identification & resolution times. Set up a training program, used by all new Incident Commanders, with knowledge requirements, training material, and the expectations of our executive leadership team.

• Joined CenturyLink Cloud as a member of their 24x7, single tier, Sr. Engineering team who resolves 96% of all tickets. Prioritizing the best customer service & timely resolution possible. • Member of the elite Network on-call rotation, where I resolved advanced network problems, both internal and customer related. I troubleshot issues ranging from custom VPN's, advanced routing issues, BGP & MPLS. • Using our chat & ticketing system, I resolved problems on a variety of topics like server performance, IPSec VPN's, our API, and the GUI where customers managed their servers. • Incident Commander, on all service impacting events during my shift. I engaged engineering teams to restore service as quickly as possible while providing clear & transparent communication to our customers and internal staff. Afterwards, I ran the retrospective, which identified gaps, immediate action items, and feature requests, so we could try and prevent a reoccurrence in the future.

• Designed, documented and executed the global Active Directory migration from a multi-forest, multi-company infrastructure to a single forest design. This paved the way for single sign-on, cross-site collaboration, tooling efficiencies, communications, and global IT support. • Standardized office deployments by designing an infrastructure template using HP switches, dual firewalls, VoIP, IPSec VPN tunnels and a global Wi-Fi solution. This reduced the amount of diverse support needs and saved the company $10k per site. • Led the project of rebuilding our ailing New York and Los Angeles infrastructure. We completed the infrastructure replacements with zero business impact and 100% functionality the next business day.

• Responsible for testing, installing, configuring, and administering all 150 systems within the network infrastructure. This included routers, switches, firewalls, servers, and VoIP phone system. • Designed & implemented a fully redundant VMware configuration where we consolidated 80% of our server infrastructure and maintained 99.99% uptime. • Preparing for a surge in growth, and VoIP requirements for the business, I redesigned our network using HP 8000 & 3000 series switches. The configuration included QoS, 802.1q, loop protection and LACP links to core infrastructure devices. • Deployed dual SonicWall firewalls in a fully redundant failover scheme where we used IDS, IPS, and a hardened firewall configuration to adhere to our Sarbanes Oxley requirements and provide 100% uptime to our business.
