Profile bio

About Sean Simon

I like the challenge of combining technology, people and business to create and develop amazing things. I hope to continue to combine my technical and leadership abilities while achieving lifelong learning and growth. I hope to travel internationally as I enjoy different cultures, history, people and perspectives.My current role has allowed me to design, test and deploy systems in support of a commercial GPRS mobility infrastructure which supports 100 million mobility subscribers. I've functioned as the packet core node owner for ATT Mobility's 3G and 4G Gateway nodes to include GGSN, SGW and PGW elements. My duties include requirements development, configuration, vendor management, test and deployment. I've also served as a principle developer in the intermediate CDR storage system which handles over 1.5 billion records per day. As the number of subscribers has increased 25 fold, I've been able to provide direction, leadership, support and guidance.Prior to working within the GPRS packet core, I worked as a network engineer where I designed and built networks to support ATT IT, customer care and retail locations. I've had many key roles to include that as a lead technical resource in the systematic upgrade of over a dozen call center locations by converging voice and data services onto a common transport method. As the mobility space grew through acquisitions, I worked as a technical lead on a select team to perform surveys and gap analysis of acquired companies. It was my role to coordinate and partner with acquired personnel to integrate and rationalize strategic IT systems or infrastructure while maintaining a positive working environment. I was recognized for my ability to develop repeatable IT business processes to reduce conflict, cost and time. I've also performed the following:Security and Incident ResponsePersonnel Recruitment and Management for Technical RolesRegulatory ComplianceForsensice InvestigationsSecurity Information ManagementSpecialties: 3GPP Mobility; SGW, PGW, GGSN, GPRS, LTE, 3G, 4G, PCRF, Ixia, SpirentEnterprise Routing and SwitchingEffective communicator using verbal and written correspondenceAbility to lead and manage a dynamic environmentCan incorporate technology and business factors into the decision making process.
