Geidel Guerra
Technical Entrepreneur & Software Developer
About
Technical entrepreneur and software developer turning business problems into useful products, services, and systems. Over more than a decade, I've progressed from shipping features to owning the bigger picture: identifying opportunities, shaping solutions, and building technology that supports a business.
I co-found practical technology ventures. Through GNG Tech Services, I help businesses with portfolio websites, custom software and integrations, and focused AI solutions for chatbots, workflow automation, and content generation. I've also launched SaaS products and served as a CTO.
I stay hands-on in the code—especially with Go and TypeScript—but measure the work by the value it creates. I enjoy taking an ambiguous idea to a focused solution that can be shipped, used, and improved.
