What I'm looking for

I am looking for opportunities that allow me to innovate and collaborate on impactful projects while continuing to grow my technical skills.

With over 20 years of experience as a Senior Software Engineer, I specialize in web application architecture and SQL database design. My recent role at Five9, Inc involved building APIs using Node.js and Express, as well as front-end development with React and Vue. I have a proven track record of collaborating with Product Managers to implement and deliver innovative products and features that meet the needs of our key customers.

Prior to my time at Five9, I served as a Senior Full-Stack Engineer at Codero Hosting, where I designed databases, APIs, and user interfaces for the customer-facing server control panel. I led the development of an in-house inventory system and created auto-provisioning pipelines to streamline customer orders. My freelance work has allowed me to partner with various clients, developing original products and scaling existing ones, showcasing my adaptability and commitment to delivering high-quality solutions.
