Building Digital
Solutions That Scale

About Me

Hi, I'm Charlie Ward

I'm a software engineer with over a decade of experience building production-grade applications. From handling US government data with millions of rows, to working with SaaS products at GrowthLoop serving major clients like Google and Walmart, to writing frontend code for big international corporations, I bring ideas to life with clean, maintainable code.

Currently, I'm focused on projects in the legal tech, AI voice, and home renovation spaces, combining modern web technologies with artificial intelligence to create innovative solutions.

Whether you need a robust enterprise platform or a consumer SaaS product, I can help you build something that scales.
