Our dApp Development Services
How to start hiring
We discuss the project with the client to identify its technical requirements and technology needs. At this stage, we can verify the availability of needed tech expertise and make preliminary estimates of work hours based on the general project idea and your expectations.
The next stage involves more detailed market and technology research on your project to plan the breakdown of costs and human resources needed for your project’s implementation. It’s a more concrete step that ends with budget and deadline roadmap planning.
If you’re okay with our provided estimates, it’s time to compile a team and get down to the actual coding. We offer candidates, you approve the final team composition, and the dedicated team works under our close guidance to deliver the project to you.
Once the dev work is over, we undertake extensive QA testing of the resulting product. Our experts run a series of automated and manual checks, review the code logic, and analyze the code’s cybersecurity before the final project submission.
