Hello, Camila,

I am Georgios Tutudakis, a full-stack developer with experience creating secure control panels based on data and API integrations in Python.

My approach:
Frontend: Next.js + Tailwind (clean, responsive user interface, JWT authentication, file uploads)

Backend: secure wrapper for your FastAPI with proper error handling

… Database: PostgreSQL for users, uploads, analyzed data

Diagrams: D3.js or Chart.js for displaying analysis results

Deployment: Docker + Render.com or Fly.io with CI/CD, SSL, and HTTPS

Services provided:
Authentication + control panel

PDF upload + result viewing

Secure backend + API integration

Ready-to-launch MVP in 2.5–3 weeks

Estimate:
$800–$1000 USD, fixed price, phased delivery

I have already created similar AI and analytics tools and am ready to help you launch them quickly and efficiently.

Best regards,
Georgios Tutudakis

Dear Kamila,
Thanks for the clear and detailed brief. Here’s how I would approach your project to deliver a lean, cost-effective MVP.

Tech Stack
Frontend: I’d use Next.js (React framework). It’s perfect for building modern, responsive apps, supports server-side rendering for speed and SEO, and integrates well with authentication solutions. For styling, I’d use Tailwind CSS, which is fast for building clean, consistent UIs. For data fetching, React Query or SWR would help manage API calls efficiently. I’d leverage a component library like shadcn/ui or MUI for quicker UI development.

Backend: I’d keep your FastAPI backend as the core for data science services. Around it, I’d build an API layer to handle authentication, user management, and file storage securely. FastAPI is excellent for building secure, performant REST APIs in Python.

Database: PostgreSQL is an excellent choice for relational data like user accounts, documents, and logs. It’s reliable, scalable, and well-supported.
…
Authentication & Security: I’d implement secure user auth with JWT tokens (probably via FastAPI’s security tools or a library like FastAPI Users). All endpoints would require auth where needed. HTTPS would be enforced everywhere, and I’d follow OWASP best practices for data validation, error handling, and avoiding common vulnerabilities.

File Uploads: PDF uploads would be handled via the backend, with documents stored either in the DB as blobs or on cloud storage (like AWS S3) depending on size and cost constraints.

Deployment: I’d containerize the services with Docker and deploy via a cloud provider like DigitalOcean, AWS, or even Render.com for cost efficiency. Nginx would serve as a reverse proxy and handle SSL termination. I’d set up a simple CI/CD pipeline (e.g. GitHub Actions) for smooth deployments.

Timeline Estimate
Week 1: Project setup, auth system, frontend boilerplate, basic routes
Week 2: File upload flow, backend endpoints integration, database models
Week 3: Dashboard UI, results display with tables/graphs, error handling
Week 4: Security hardening, deployment setup, polishing, testing

Rough total: 3-4 weeks for a first usable MVP, assuming fast feedback cycles and availability of your existing API and any documentation.

Cost Estimate
For an MVP as described, I’d estimate roughly €4,000 - €6,500 depending on final scope and features. This assumes solo development, not an agency team.

Good day!

I am very interested in your proposal. I am a FullStack Web developer with experience in stacks such as PERN, MERN, PEVN, MEVN. I work with modern technologies: Node.js (NestJS), React.js (Next.js), PostgreSQL, and other tools from the JavaScript ecosystem.

Here is what I can offer you:
- Clean and maintainable code — using ESLint and Prettier to ensure the code is structured, readable, and easy to support;
- Clear architecture — the entire project structure will be logical, without chaos or "confusing forests";
- Modern technologies — using up-to-date solutions on both the frontend and backend;
- Quality and timely development — I work responsibly, adhering to deadlines;
… - Pixel-perfect responsive design;
- Website localization;
- SEO — optimization for search engines;
- Precise implementation of requirements — everything will be realized according to the specified technical task.

If you are looking for quality, clean architecture, and a responsible performer — I am available!
