As a Senior Software Engineer at Tractiv, I led the design and development of the backend stack and structure, using Node.js, GoLang, and AWS technologies. I built file encryption flows, an immutable ledger, and an internal load/connection balancer for our immutable data store, translating shareholder wants and needs into architectural features.I have a certificate in Full Stack Web Development from Galvanize - Boulder, West Pearl, where I learned how to build web applications using various frameworks and languages. I also have experience as a Full Stack Developer at Ideas By Nature, where I built blockchain monitoring and validation solutions for clients, using TypeScript, Kotlin, and Postgres. I am passionate about solving difficult problems and teaching others, as I demonstrated by volunteering as an Alexa Development Clinic Teacher.
