Freelance Gig: Build a B2B SaaS App (Frontend: TanStack, Backend: Go)
Budget: ₹10,000 INR (fixed)
Engagement: Freelance / Contract / part time
Start: Immediate / ASAP
Delivery: MVP with clean code + docs
Overview
We’re looking for a freelancer to build a lightweight B2B SaaS MVP using TanStack (React + TanStack Query/Router/Table as needed) on the frontend and Golang on the backend. You’ll implement core SaaS foundations: auth, roles, CRUD modules, and a production-ready API with documentation.
Tech Stack (Required)
Frontend: React + TanStack (Query, Router, Table if applicable)
Backend: Golang (any solid framework is fine: Gin/Fiber/Echo)
Database: PostgreSQL
API Docs: Swagger + OpenAPI spec (must be included)
Scope (MVP Features)
Authentication \& Authorization
Person signup/login (email + password) or passwordless (suggest approach)
Role-based access control (e.g., Admin, Member)
B2B / Multi-tenant Setup (basic)
Company/Organization workspace with People membership
Core Module (CRUD)
One primary business entity (e.g., Customers/Leads/Projects — implement as agreed)
List + filters + create/edit/delete
Admin basics
Manage People, roles, and organization membership
API + Documentation
REST API (preferred) with OpenAPI/Swagger
Clear request/response contracts
Quality
Input validation, error handling, basic logging
Clean structure, readable code, and setup instructions
Deliverables
Source code repo (frontend + backend)
PostgreSQL schema/migrations
OpenAPI spec + Swagger UI
README with setup steps (local run) and environment variables
Minimal seed data or test flow to verify the MVP
Nice to Have
Docker Compose for local setup (API + DB)
Basic unit tests for key endpoints
Simple deployment notes (Render/Fly/Railway/etc.)
Requirements
Prior experience building SaaS-style apps (multi-tenant + auth)
Strong Go backend fundamentals
Comfortable with TanStack patterns and API-driven UI
