Questions We Hear Every Week
It depends on scope. A focused internal tool starts in the low five figures, while a full enterprise platform runs higher. After a free discovery call you get a clear, fixed-price quote with no hidden costs.
Most projects ship a first working release in 6 to 12 weeks. A small tool can be faster, and a large platform is built in phases so you see value early and add features over time.
Four clear phases: discovery and architecture, design and prototyping, agile build in short sprints, then deploy and support. You review working software and give feedback every step of the way.
Yes. You own 100% of the source code, documentation and intellectual property, handed over in your own repositories with no lock-in. We sign an NDA before any discovery conversation.
We build with React and Next.js on the front end, Node, Python or Java on the back end, PostgreSQL for data, and deploy to AWS or Azure using Docker and Kubernetes. We pick the right tools for your project, not a fixed template.
Yes. After launch we offer monitoring, security updates, bug fixes and new feature development under a support plan that fits your needs, so your software keeps improving over time.
