AT&T

- Experience with solving routing issues in the world's largest MPLS network.- Ability to work in multi-vendor environment- Lead figure in a DEV-OPS initiative that's responsible for developing tooling solutions used by the AT&T's backbone team. - Developed tool(PciTool, CakePHP3) that is used to schedule and carry out PCI (Planned Cable Intrusions) based on a list of circuit ids and proposed time of the event. Using various microservices and hooks to other systems, PciTool is able to: - retrieve circuit engineering and create a logical representation of the circuits from the Layer3 perspective - Generate MOP - exact step by step guide with correct cost-out / cost-in commands - Schedule the event on the GoSET calendar, used by operations to track maintenance activities. - Track Event's lifecycle (Cancellations, Rescheduling, Completion) and update the calendar accordingly.- Developed tool (fspare, perl) to enumerate unused cards in production routers, usable as a spare in an outage situation. Fspare helps to reduce the outage time and restore customer service.- Developed tool (eshoot, python3), that helps with troubleshooting evpn service on JUNOS platform.- Developed tool (password audit, python3) which is used to audit local passwords of last resort and snmp community strings. Password audit is integrated with Network Password Manager, which allows for secure storage and provides accounting and secret history capabilities. Password audit is also used to change the local password and snmp community strings. Tool is vendor agnostic and uses dynamic templates in order to create the correct configuration command.- Leading the effort to create a new environment for DEV-OPS subteam. Created deployment script (bash) that's able to bootstrap the whole docker based environment from scratch in an event of catastrophic failure. Utilizing services, environment consists of haproxy and LA(M)P containers running workloads.
