About Me

I am a highly driven and successful technology professional with a proven record of leading teams, implementing change and exceeding targets. I bring an analytical, persistent and detail-oriented focus to work every day.

I am currently a Software Development Manager where I independently manage a team of engineers working on Amazon's Environment, Health, and Safety (EHS) system which is used in 42 countries, at over 4000 sites. The system has 60k active monthly users responsible for the environment, health and safety of over 1.6M Amazon employees world-wide. I participate in the full software development lifecycle from conception through on-call production support. I collaborate with other teams across Amazon including other engineering teams within and outside our organization. I actively coach and mentor engineers in their careers.

Previously, I was a Senior Technical Program Manager at Amazon where I led multiple technical programs. I expanded the driver to customer texting feature to more than 500k drivers using our mobile application on Android and iOS in 11 countries resulting in an increase in first time delivery success of 10%. I also migrated delivery driver to customer phone calls to Amazon Connect in Great Britain, Germany, Italy and France enabling features including local numbers and caller id. In addition, I launched a backend service and web console used by 150+ content authors to deliver ~30,000 external customer facing help topics available on amazon.com, mobile apps and devices.

Before Amazon, I worked at AT&T. My last role at AT&T was as a Principal System Engineer. In this role I led the effort to migrate a Fortune 25 company to a new network management system involving 70,000 devices in 2100+ locations without a single store impacting incident. In this role I implemented a solution which automated the monitoring of over 100,000 switches, access points and controllers which reduced support ticket generation time by over 50%.

Before this role, I led the Unix to Linux program as an Associate Director Technology. The program was responsible for migrating 1000 internal IT applications from their Unix infrastructure to x86 Linux hardware to help drive operational costs from the business. This program delivered over $100M in application run rate cost reduction, over 33% average improvement in application performance and decommissioned over 2500 physical servers.

Senior Technical Program Manager• April 2019 - April 2022

As a Senior Technical Program Manager at Amazon I delivered several technical programs. First, I delivered several key programs for Amazon's Environment, Health, and Safety (EHS) system including a new landing page experience as well as several new services for the platform including a new scheduler and an activity history service. I also expanded the driver to customer texting feature to more than 500k drivers using our mobile application on Android and iOS in 11 countries worldwide resulting in an increase in first time delivery success of 10%. I also migrated delivery driver to customer phone calls from a legacy calling system to Amazon Connect in Great Britain, Germany, Italy and France enabling features including local numbers and caller id. In addition, I launched a backend service and web console used by 150+ content authors to deliver ~30,000 external customer facing help topics available on amazon.com, mobile apps and devices. The backend service/web console automates previous manual activities in addition to adding features including batch and scheduled delivery of content which was not supported by the previous system.

AT&T

Principal System Engineer • Octoboer 2016 - April 2019

As a Principal System Engineer I migrated a Fortune 25 customer to a new network management system involving 70,000 network elements in 2100+ locations without impacting production operations. I developed the migration process and coordinated activities between multiple internal and external groups including development, network engineering, operations, product and customer relations. It was one of the largest migrations of its kind. I also reduced the average support ticket creation time by 10 minutes by implementing Netcool monitoring software and integrating it with Salesforce. In addition, I improved device status accuracy in the customer portal 10% by developing Python automation scripts. In my role, I collaborated with customers, stakeholders and suppliers to understand products being on-boarded and established system requirements for development teams to deliver those products. I participated in planning, definition and high-level design of solutions and explored solution alternatives ensuring the most cost effective, resilient and adaptable solutions are developed. I was responsible for the creation of EPIC's and User Stories as well as the grooming of those stories.

AT&T

Associate Director of Technology • June 2015 - October 2016

I led the Unix to Linux program consisting of a diverse group of local and remote employees and contractors and was responsible for the migration of 1000 applications from Unix to Linux. The program had a budget of $100M+ and involved hundreds of independent projects. The migration to Linux is the first step for enabling many of AT&T's internal applications to utilize our Cloud infrastructure. I was responsible for the planning, assessment, financials, decommission and client support of the migrations. This program delivered over $100M in application run rate cost reduction, over 33% average improvement in application performance and decommissioned over 2500 physical servers.

AT&T

Principal Technical Architect • April 2013 - June 2015

I was the lead for the Unix to Linux Assessment Team. I was responsible for the planning and assessment of 1000 applications that were being targeted for migration from Unix to Linux. I conducted both technical and financial assessments of applications to ensure they were a good fit for the program. In order to efficiently conduct these assessments, I created a migration effort estimate model as well as a hardware scoring algorithm to be able to compare applications against one another. I also served as the Agile product owner for tooling needed by the program for planning and tracking. I collaborated with a team of developers using the Agile Kanban methodology which delivered the first version of the tool in six weeks. This tooling was the first of its kind in the company to combine data from multiple internal data sources including the application database, midrange database, project financials, ordering system and software standards system. This tool combined these isolated data sets into a single view and is now used by multiple groups within AT&T.
