Need a web application, ecommerce solution, or AI workflow that connects with your existing systems? I help businesses build, modernize, and integrate software—from the user interface and backend to databases, APIs, and automation. I’m a Sr Full Stack Developer specializing in custom software, enterprise integrations, and AI-powered applications. I turn complex business requirements into practical systems that improve operations, reduce manual work, and support growth. At Pearl Health, I worked as a Technical Lead Engineer and business advisor, supporting legacy and enterprise healthcare systems. Using Python, React, PHP, WordPress, and HubSpot CMS, I led application modernization, API integrations, workflow automation, and performance improvements. I also helped align technical capabilities with value-based care partnerships, independent primary care practices, and post-acute care networks. I bring that same approach to client projects: understand the business, design the right architecture, and deliver software that people can use and maintain.
