I help organizations connect systems, reduce manual work, migrate data, and build practical web, mobile, and hardware-connected tools that support everyday operations.

I'm actively pursuing opportunities to lead Business Transformation initiatives.

Who I Help

I help small businesses, nonprofits, and growing teams reduce manual work by connecting systems, cleaning up data, building practical web/mobile tools, and modernizing older workflows.
