Full-Stack Developer Wanted (Web Application – SaaS / MVP) Project Description We are looking to develop a web-based SaaS/MVP focused on digitizing financial operations. The project covers both backend API and frontend panel development. Our goal is to build a scalable, clean-code foundation that can be extended modularly in the future. This is not a “single-page website” — it is a real product infrastructure. General Scope 1. Backend (API) RESTful API architecture Authentication & Authorization (JWT or similar) Role-based access control (e.g., admin / company user) CRUD operations Email sending (password reset, notifications, etc.) Excel/CSV import (optional but a plus) Clean, well-documented endpoint structure Technology preferences (open to suggestions): Node.js (NestJS / Express) or Python (FastAPI / Django Rest) PostgreSQL / MySQL / MongoDB ORM usage preferred 2. Frontend (Web Panel) Modern, responsive web interface Dashboard structure (KPI cards, tables, listing screens) User login / password reset Forms, list views, and detail screens Light / Dark mode (preferred) Full integration with backend APIs Technology preferences: React / [login to view URL] Tailwind / MUI / or similar modern UI libraries 3. General Expectations Clean, readable, and well-structured codebase Version control (Git) Basic documentation (setup, environment variables) MVP mindset: no unnecessary complexity, but not amateur Open and clear communication during development Project Status The project will be developed from scratch Detailed workflows and screen lists will be shared with the selected developer The architecture should support adding new modules in the future Who Is a Good Fit? Experienced in full-stack development Previously worked on SaaS / dashboard / admin panel projects Developers who understand what they are building (not “I do everything” mindset) Can work solo or as a small team Please Include in Your Application: Similar projects you’ve worked on (links or repositories) Backend and frontend technologies you use Estimated development timeline Preferred working model (fixed price / milestones / modular) Note This project has the potential to evolve into a long-term product. If the collaboration goes well, follow-up projects are planned. If you want, next I can: Align this English version fully with the FizeTech ERP-SaaS vision, or Rewrite it as a short, high-conversion Upwork/Bionluk listing, or Remove items that conflict with your finalized scope (roles, light mode, etc.). Just tell me how strict you want it to be.

As a seasoned full-stack developer with a vast portfolio, including custom web applications, I believe I embody the best of both worlds for your envisioned project. My experience in developing platforms similar to yours such as CRM and ERP systems, aligns impeccably with your SaaS/MVP design. On the backend, I have proficiency in both Node.js and Python/Django, which present solid options for crafting a RESTful API architecture that supports complex CRUD operations while prioritizing data security via authentication and authorization protocols. In line with your stack preferences, Frontend skills in React.js/Next.js will assure you receive a clean code structure with user-friendly interaction using modern UI libraries such as Tailwind. Additionally, I am adept at leveraging ORM on databases like PostgreSQL and MySQL which will provide you a reliable base for your extensive use of Excel/CSV files Thanks...
