# Perry Rosenberg > Princpal Software Engineer, Software Architecture, Cloud at Scale Location: San Francisco, California, United States Profile: https://flows.cv/perryrosenberg I'm a principal engineer and architect with a decade of experience designing and scaling high-traffic, cloud-native systems. Known for end-to-end ownership of complex initiatives and driving transformative technical outcomes. I am equally confident driving solutions hands-on with code, leading engineering teams, and mentoring talent. I work to deliver lasting product success by creating alignment across executives, product/technology, and customers. As an architect, I solve problems by engaging in every aspect of a project. To build a product/business that will last, you need that depth of understanding from the customer to the infrastructure. As a leader, my style centers on trust, collaboration, and empowering others. I take a mentorship-first approach to give people the tools and skills they need to succeed and grow. I look to bring a long term view to any product or business - today's shortcut or overcomplexity is tomorrow's headache. Doing things the right way while delivering what is needed at scale is the best way to prepare for the future. ## Work Experience ### Principal Software Engineer @ Extensiv Jan 2021 – Present | San Francisco, California, United States - Leading the technical vision for Order Management (OM) SaaS application, reporting to the CTO and Chief Architect - Led a multi-product team of 14+ engineers, architects, product owners, etc to upgrade a central MySQL database used across products, to transform database CPU usage and spend on a short timeline.
