9592 Solutions
I build custom software. Before you commit to a contract, you get a working version of what you asked for, deployed and open in your browser.
[email protected]What I do
9592 Solutions is my company. You work directly with the developer doing the work, you have one contracting party, and there is nobody in between.
I work across the stack: backends, web and mobile apps, data processing, and the infrastructure to run all of it in production. If a project doesn't make sense in the form you have in mind, I'll say so before we start.
Services
If you buy software through a formal procurement or purchasing process, the prototype is the thing you evaluate. You can open it, click through it, and put it in front of the people who will have to use it, before the contract is awarded.
