This project needs a backend that is structural, predictable, and fast to extend. I design PostgreSQL schemas and workflow engines where jobs, applications, payment-sharing records, admin views, and notifications operate as one coherent system. I work with Prisma, queue workers, and clean REST endpoints that map directly to your Figma flows so the Turkish UI consumes stable, typed responses. What I will deliver: • Normalized PostgreSQL schema, migrations, seeds, and a clear data contract. • Endpoints for urgent jobs, salaried jobs, solidarity payment-sharing, assignments, and payment record intake via webhook. • Admin filters, exports, manual collection logic, and role gating. • Notification worker for in-app plus email delivery with queued reliability. • Postman collection, README, staging deploy, and smoke-test output. If you want, let us open the chat and I will share similar workflow-driven backends I have shipped and give you my ETA and fixed price. Best, Jenifer.

volkana6, for the Node.js Backend & PostgreSQL Workflows project, would it be fine if I handle the DB schema design, migrations, and seed using Prisma or another ORM, then develop API endpoints for urgent & salaried jobs, restaurant/market payment-sharing flows, applications, and assignments? So I believe the outcome will be a seamless integration of PostgreSQL DB and server workflows to enhance the functionalities of the web UI, ensuring a smooth user experience in Turkish. By the way, could you provide more insights into the existing tools or frameworks in place to better align the backend development process with the project requirements?
