Steps for completing your project
After purchasing the project, send requirements so Andrii can start the project.
Delivery time starts when Andrii receives requirements from you.
Andrii works on your project following the steps below.
Revisions may occur after the delivery date.
Estimation- Discovery
I analyze your business goals, define the technical scope, select the optimal stack (React/Node/AWS), and create a detailed DB schema and system architecture diagram to ensure scalability.
UI/UX Implementation & Frontend Setup
I build the visual foundation using React 18, Next.js 14, and Tailwind CSS. We implement responsive layouts, Shadcn UI components, and state management (Redux/Zustand) for a seamless user experience.
