    I’m Michael Dunn.

    Full-stack engineer designing and building scalable web applications and marketing systems in Minneapolis.

    Most of my work sits where engineering meets marketing operations — the CRM, the forms, the tracking, the reporting layer nobody sees until it breaks. I work with agencies and B2B teams that have outgrown their stack.
