Professional Summary


Full Stack software engineer with 19 years of experience delivering custom software solutions across multiple industries, with a proven track record of managing all stages of product development, from greenfield projects to automated cloud deployments. I've shipped across many stacks based on client needs, and now specialize in Go (Golang), Svelte, TailwindCSS, and PostgreSQL. I value clean code and simplicity over abstraction, and bring both leadership and mentoring experience to the table. I use AI tools for code review and accelerating routine implementation, while keeping ownership of core implementation decisions.
