We need to hire a full stack web developer. I think web development is not your field, right? Do you know someone who is good at web development? The tech stack is React, Node.js, GraphQL, PostgreSQL, etc.
Before hiring, we need to do a paid code assessment. We do offer a $100 flat fee for our contractors who take this test, as we know your time is valuable. If everything does look good with the code, then we will go ahead with bringing the contractor on to the team.
I attached the code assessment.
