About Me

I am an experienced Javascript/Node.js Developer with an extensive background in web development, CRM implementation, integration development, and API development. I identify and provide the most cost-effective high quality solutions available to effectively resolve even the most complex business problems. By dividing complex tasks into manageable subtasks, I create sprint structures according to Agile methodologies. Working independently or on a team, I collaborate with clients throughout every project, building strong relationships while providing clear and consistent communication from inception through completion.
