Full-stack Developer in Mesa, United States

Member since August 4, 2021
Will taught himself JavaScript to build a CRM solution for a previous employer. The CRM prevented thousands of clients from slipping through their system. While this success saved the company millions of dollars, his greatest takeaway was his newfound love for programming. Seven years later, his motivation is the same–to build software that matters. Will aims to provide the highest quality product on the market while using the latest technologies in the industry.

  • Senior Software Engineer

    2021 - 2022
    • Architected and implemented a data feed ingestor and digestor. This back-end worker ingested updates from multiple third-party APIs with different properties and digested them into a headless REST API that fed our mobile and web apps.
    • Improved operations by introducing better practices like testing (Jest + React Testing Library), using a component library that I architected, eliminating bloatware, and spending time working on tech debt each sprint.
    • Brought design and engineering together to build a system that would foster a seamless transfer between the two groups. This was done through the use of Tailwind CSS, which enforced our shared design system.
