  • Launching & Growing Square Online Store

    Within 1 year of Square's $365M acquisition of Weebly, I led the complex integration of Weebly's professional website building technology with Square's Point of Sale item catalog and inventory systems to launch the new Square Online Store.

    Square Online Store was the pivotal component to unlocking Square's omnichannel vision – empowering brick and mortar Square sellers to begin selling online, and online-only Weebly sellers to begin selling in-person through one cohesive, remarkable solution.

    After initial launch, I directly oversaw strategy, roadmaps, execution, and revenue of Square Online's merchant-facing tools and platform. My teams managed all aspects of order fulfillment (delivery/pickup/shipping), item catalog/menu management, store operations, taxes, checkout platform, payment integrations, and international expansion.

    Initially launched with a focus on sellers in the Retail SMB industry, we began expanding to target upmarket sellers and serve the needs of Restaurant and Services businesses, going from zero to millions of monthly online orders and billions of dollars in processing volume within a year.

  • Scaling online ordering through a pandemic

    Just as we began to expand Square Online's target customers beyond Retail shops to Food & Beverage, indoor dining and shopping restrictions took effect across the country in March 2020. Square sellers immediately felt the impact as their revenue was cut off – especially those yet to embrace online ordering.

    As the Product Lead for Square Online's merchant-facing tools, I led both our immediate response and action plan, as well as the re-prioritization of our roadmap to respond to rapidly-changing seller needs. Within days of lockdowns beginning, we launched curbside pickup and local delivery functionality, and successfully scaled our platform with the resulting 60x increase in monthly order volume.

    To help sellers own their customer relationships and take back their margins, my team launched a new 0→1 product and business in On-Demand Delivery, partnering with DoorDash and Uber to offer seamless courier delivery of millions of online orders for tens of thousands of restaurants.

    During this period of intense growth, I drove and sponsored key strategic shifts and active seller growth unlocks by focusing on catalog/menu completeness and frictionless setup, simplified ordering page set up, and establishing principles for store operational excellence.

  • Integrating Weebly into Square's Omnichannel Vision

    In 2018, the partner integration and relationship that I and my team built enabling Square merchants to sell online through Weebly led directly to Square's $365M acquisition of the company.

    Square's vision was for their 4 million sellers to seamlessly sell both online and in-store through a cohesive omnichannel experience.

    Upon joining Square, I led the strategy and multi-year effort across dozens of product and platform teams to turn Weebly into Square's eCommerce platform and champion an omnichannel-first mindset across the organization. This involved leading both short-term and long-term prioritization decisions, roadmap planning, and difficult sunset conversations to integrate Weebly and Square into one cohesive experience for sellers.

    This foundational work ultimately led to the launch and growth of numerous new products (e.g. Square Online, Payment Links fka Online Checkout), remarkable omnichannel experiences across the Square ecosystem, and billions of dollars of GPV growth.

  • Growing Weebly's B2B Offerings for Designers, Resellers, & Enterprises

    As the Principal PM for all of Weebly's partner products, my team worked every day to provide the website, commerce, and marketing tools needed for partners of any size to start and grow their own businesses.

    Weebly Cloud enabled resellers and enterprises to co-brand or white label Weebly's easy-to-use website builder as part of their own product offerings – such as a domain registrar offering website bundles, or a large school system giving all teachers their own sites.

    I worked closely with our Sales team to refine our target customer and product strategy, understand the needs of those customers firsthand, and quickly ship product enhancements, ultimately growing the business 35% each year.

    For website designers, one of Weebly's most passionate customer groups, my team started from first principles to create a new, modern platform for designers to build more advanced sites and manage their clients based entirely on user research and pain points of both current and potential customers. We ultimately launched this new 0→1 product, Weebly for Web Designers, and migrated thousands of designers to sunset our legacy product, removing a tremendous tech debt burden.

    These partner products accounted for a combined 10% of Weebly's revenue.

  • Launching Weebly's App Center & Developer Platform

    As the leading drag-and-drop website builder powering everything from wedding sites to online retailers, Weebly was ready to open up its platform for third-party developers to take its capabilities to the next level.

    I launched and managed the Weebly App Center and Developer Platform, including all aspects of product, policy, and operations, as well as designing the app extensibility experiences throughout the product. This included, for example, the brand new home dashboard enabling apps to create custom card components to surface realtime stats, action items, and other key information.

    Ultimately, 40+ million Weebly users had access to hundreds of apps to make their businesses more successful.

  • Leading Firefox Browser Customization at Global Scale

    When you think of Mozilla Firefox, there's a good chance you think of its deep customization capabilities and powerful third-party add-on ecosystem.

    From 2009-2013, as Firefox grew to 30% worldwide market share, I led the Firefox Add-ons team and ecosystem – launching new marketplace experiences for users to discover their favorite add-ons, ensuring the security and quality of the add-on submission process, supporting and growing our passionate open source community, and lowering barriers to extension development through improved developer tools and resources.

    As a result, 400 million Firefox users downloaded more than 3 billion add-ons in dozens of languages, all possible through the experiences I and my team loved creating.
