Senior Executive | AI & Data Analytics | Telecommunications | Strategy & Operations As a Technology and Product Leader with over 20 years of experience, my career has been defined by a unique ability: serving as a strategic bridge between complex engineering and high-level business goals. I have had the privilege of building my career within global Fortune 500 organizations, including Verizon, Walmart Global Tech, and Samsung Networks, where I have led digital transformations that generate measurable impact.Bridging Technical Innovation with Strategic Business Growth. As a Technology & Product Leader with 20+ years of enterprise experience, I specialize in architecting scalable infrastructure, managing cloud ecosystems, and operationalizing Artificial Intelligence to eliminate friction and drive revenue. Having scaled tech delivery at Verizon, Walmart, and Samsung, my value proposition lies in a unique dual lens: the rigorous discipline of an Electronics Engineer combined with the commercial and financial acumen of an MBA. What I bring to the table: AI & Cloud Delivery: Experience moving models from prototype to production (from AI-driven logistics infrastructure to transitioning 3,000+ virtualized servers). Data-Informed Optimization: Expert in leveraging Power BI, Tableau, and Machine Learning to reduce service failure rates (e.g., achieving an operational drop from 35% to 7% at Verizon). Enterprise Governance: Seasoned leader in cross-functional collaboration, technical pre-sales, vendor management, and strict SLA compliance under Agile/ITIL frameworks. I thrive in high-velocity environments where I can act as the primary liaison between engineering teams and C-level executives to deliver measurable ROI. Let's connect!
