Andrew McConnell

Senior Software Engineer

As a fullstack developer, helped develop and launch Square's Subscriptions from beta to a publicly available API, integrated across Square's first party platforms. In 2023, the Square Subscriptions platform had 22k active sellers, 388k active subscriptions, and processed $178M in yearly recurring revenue.

• Designed, built and maintained the first-party Subscriptions offerings on the Seller Dashboard and Buyer Management portal, where the buyers and sellers of Square Subscriptions could create new or manage existing subscriptions, with extensive configurability.
• Collaborated extensively with other teams to ensure cohesive integration of the Subscriptions API across other Square offerings, such as Subscribe & Save functionality on seller websites.
• Built out substantial internal tooling to improve or eliminate common problems, such as recurring oncall issues that wasted developers' time, or admin dashboards to give stakeholders insight into project progress.
• Ran a number of learning and development opportunities, such as new employee orientation, team-scoped knowledge transfers, conducting technical interviews, and intern mentoring.
