Full-Stack Web Application Development

Web applications where the interface, the server-side logic and the data are designed together — React and Next.js on the front end, Python on the back end.

What this covers

  • Multi-page websites and web applications.
  • Interfaces for working with a backend: forms, lists, details and actions.
  • Client applications and admin panels.
  • The backend and the database behind them.

How it is built

  • Validation on both sides: the browser checks input instantly; the server checks it again, because a request can bypass the form.
  • The server is the source of truth: conflicts such as a slot that was just taken are resolved there and returned as clear answers.
  • Related data changes run in one transaction.
  • Pages are rendered on the server for a fast first view and for search engines, then become interactive.

Technologies

  • React
  • Next.js
  • TypeScript
  • Python
  • Django
  • FastAPI
  • Flask
  • PostgreSQL

How I work

Every project goes through the same steps. Scope, timing and cost are agreed after discovery, when the problem is clear. The contract and invoices go through my individual entrepreneurship registered in Armenia.

  1. 01

    Discovery

    We clarify the problem, the people who will use the result, the data and the systems involved.

  2. 02

    Solution design

    I propose an architecture and the scope of a first working version, and we agree on it before building.

  3. 03

    Development

    The system is built in small steps you can see and comment on.

  4. 04

    Validation

    Each part is checked with tests, real runs and a look at the edge cases.

  5. 05

    Delivery

    The result goes into your repository and environment, with an explanation of how it works.

Questions

Do you build only the front end or only the backend?

Both are possible. The advantage of building both is that the interface and the API are designed together, so they fit.

Which backend framework would you use?

Django, FastAPI or Flask, depending on the application. Django suits apps that need its ORM and admin, FastAPI suits API-first services, Flask suits small focused services.

Have a system to build?

Describe the problem in a few sentences. I'll reply with questions and a proposed approach.
