I build from Ghana. The products get used everywhere.
Hi, I'm Allen Jones.
I've spent six years shipping production software. I currently work as Senior Software Engineer at Green Vision Solutions in Germany. Alongside that, I've spent the past year building Formgrid.dev on my own, at night, from writing the backend to writing the blog posts that got it found. A lawyer in Brazil found it through Perplexity AI. An event manager in San Diego upgraded the same day she signed up. Neither of them cared where it was built. They cared that it worked.
I hold every project to that same standard. It has to work for the person with the problem.
