Steps for completing your project
After purchasing the project, send requirements so Andrew can start the project.
Delivery time starts when Andrew receives requirements from you.
Andrew works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1 — Collect requirements
I review your technical requirements, user flows, and needed endpoints. We clarify API structure and data models before development begins.
Step 2 — API development
I build your NestJS backend: authentication, database integration, endpoints, validation, and error handling. You receive updates and progress checkpoints.
