Service

Full-stack development

API, authentication, data, and interface in one cut. The back of the frontend is not empty — the product looks complete from a distance and works up close.

One team, one responsibility: the same plan from screen to database. The “UI is ready, backend later” gap is closed.

Who it fits

Which need this service answers.

  • Product teams

    Those who want to turn an MVP or an existing showcase into a real application — API + UI together.

  • Internal company systems

    Those who need a portal, a panel, and integrations; a “pretty page” is not enough.

  • Those working with an existing stack

    Those who want to connect to a ready API or database, but to bind interface and permissions professionally.

Arxitektura

Three layers. The same plan.

Əvvəl sərhəd, sonra ekran. Interfeys, API və verilənlər ayrı yaşasa da, bir kəsimdə bağlanır — boş mock yox, işləyən dilim.

Use cases

The same foundation. Different depth.

A project does not need all of them. The cut is chosen for your need — then growing stays easy.

    POST /v1/auth

    GET /v1/session

    List, filter, edit, and report. The frontend is not only a table — real operations.

  • A bridge to an external system

    REST explorer

    GET /v1/session

    Request

    Authorization: Bearer

    Accept: application/json

    Response

    { "role": "admin",

    "exp": 3600 }

    Payment, email, CRM, or ERP APIs are connected with a safe boundary.

    Design or frontend exists, but there is no backend — data and auth are added.

Problem

Why an ordinary site is not enough

When only the interface is ready, the product stops: where is data stored? Who can see what? How are payment, email, or CRM connected? When frontend and backend move by separate hands, integration is late, permissions stay weak, and every change becomes double cost. Result: a nice screen, an empty system.

Solution

What is built

REST API, role-based access, the data model, and the application layer are designed together. Domain and permission boundary first, then the interface. Result: a reliable API, clean data, and a UI that works against it — in the same cut, with the same discipline.

Paralel quruluş

Backend və frontend eyni planda. Boşluq qalmır.

Outcome

What changes in your business.

  • 01

    No empty backstage

    The screen takes data from a real source: authentication, CRUD, and business rules work.

  • 02

    Who can do what is clear

    With a role and permission model: admin, operator, and customer are safely separated in the same system.

  • 03

    An API ready for integration

    Mobile, PWA, or third-party services can connect to the same contract.

  • 04

    Maintainable code

    Type safety, clear module boundaries, and documented flow — growing later stays easy.

Process

How we move.

  1. 01

    Discovery

    We clarify business rules, user roles, existing systems, and the success criterion.

  2. 02

    Contract

    API, data, and permission boundary are written. Agreement first, then code.

  3. 03

    Build

    Backend and frontend in parallel, but on the same plan. A working slice every sprint.

  4. 04

    Delivery

    Test, security check, deploy, and a short document. Then a measured next step.

Delivery

What you receive — a clear list.

  1. 01Domain model and API contract (endpoints, errors, version)
  2. 02Authentication and role-based authorization
  3. 03Data schema + migration approach
  4. 04Binding the UI to the API (loading, error, empty state)
  5. 05Core integrations (agreed list)
  6. 06Delivery: deploy note, short API explanation, next cut

Difference

Why this approach.

  • One chain of responsibility

    There is no “frontend ready, backend is someone else’s job”. The gap does not stay in your product.

  • Boundary first, then the screen

    Permissions and the data model are clarified early — then the UI is bound quickly and safely.

  • Honest scope

    Every integration and module is written in advance. There is no hidden “we will add it later” list.

Features

  • REST API — a clear contract, predictable errors
  • JWT / session and role-based access
  • Data architecture (SQL Server or PostgreSQL)
  • Cloud and third-party API integrations
  • Validation, logging, and basic monitoring readiness
  • UI + API in the same cut — it does not end with empty mocks

Frequently asked

Can you connect to an existing API?
Yes. First the contract, authentication, and security boundary are agreed, then the interface is bound to it.
Is backend-only or frontend-only also possible?
Yes. Full-stack is usually together, but one side can be cut to the need — the scope is written clearly.
Which database is chosen?
According to project scale, existing stack, and operational demand. Not for fashion — for fit.
How long does it take?
It depends on module count, integration depth, and dependence on an existing system. A concrete timeline is given after the first meeting.
How is the price determined?
By API scope, role model, UI depth, and integrations. No invented fixed package — an offer after the brief.
