Custom web apps, SaaS MVPs and AI tools we have built.
We are D Tech Solutions, a small studio that builds custom web apps, internal tools and SaaS MVPs. We also add AI automation, such as chatbots and workflow tools, when it saves real time.
We work with two kinds of people. The first is US business owners, such as HVAC and rental shop owners, who want one simple app in place of notebooks, chat threads and spreadsheets. The second is startup founders who need a working first version fast.
Below are two demo projects: an HVAC job management app and an equipment rental booking app. We built them as working samples to show the quality of our work. They are not client work, and all their data is fake. You will also find case studies of three products we shipped. Pick one, then book a free call.
