Mark Spirek.

I help startups, agencies, and ecommerce brands build the tech that moves products and grows businesses.

Who am I?

I'm a software engineer with 15+ years helping companies turn ideas into real, revenue-generating products. I've built marketing platforms, ecommerce storefronts, sweepstakes engines, and the kind of digital experiences that make people click 'buy now.' I work best at the intersection of engineering and marketing technology — where clean code meets conversion rates and a well-architected stack means the difference between scaling and scrambling.
