Programming Languages and Technologies for Web and Mobile Development

We choose the technology stack to fit your product's architecture and goals — PHP, C#/.NET, Java, Python, JavaScript, TypeScript, Node.js, React, Angular, Vue.js, C++, Go, Flutter, React Native, Kotlin, and Dart.

A Technology Stack for Building Modern Digital Products

Promodex uses modern backend, frontend, and mobile technologies to build corporate websites, ecommerce stores, SaaS products, portals, online services, mobile apps, and custom business systems.

We don't pick technologies for their popularity. We choose them based on architecture, functional requirements, expected load, integrations, scaling plans, and long-term product support.

Backend, Frontend, and Mobile Technologies We Use

How We Choose Technologies for a Project

Your technology stack affects development speed, scalability, integrations, performance, and the long-term cost of maintaining the product.

Before development starts, we assess business requirements, architecture, expected load, the complexity of backend logic and the frontend interface, third-party APIs, databases, and the future roadmap.

Backend Technologies

The backend handles business logic, data management, authentication, integrations, APIs, and other server-side processes.

For backend and systems development, we use:

  • PHP — web applications, ecommerce, corporate systems, and custom backends;
  • C# / .NET — enterprise applications, APIs, and corporate integrations;
  • Java — complex backends and enterprise systems;
  • Python — web backends, automation, data processing, AI, and analytics solutions;
  • Node.js — APIs, SaaS, real-time, and server-side applications;
  • Go — high-performance backend services, APIs, and concurrent systems;
  • C++ — performance-critical software and system components.

PHP

PHP remains a practical choice for web development, ecommerce, and business applications. We build new PHP projects and modernize existing systems, including APIs, integrations, and performance optimization.

C# and .NET

We use C#/.NET for corporate web systems, APIs, integration services, and long-lifecycle applications with complex domain logic that call for a well-structured architecture.

Java

Java is a strong fit for enterprise backends, integration platforms, and large systems where scalability, a mature ecosystem, and long-term maintainability matter.

Python

We use Python for backend development, APIs, automation, data processing, data science, machine learning, and AI-related functionality.

It is especially convenient for products where a web application works alongside analytics or data-driven components.

Node.js

Node.js lets you use JavaScript or TypeScript on the server side. It is well suited for APIs, SaaS, integrations, real-time functionality, WebSockets, and other backend scenarios.

Go

We use Go for backend services, APIs, and systems that demand performance and concurrency with a relatively simple deployment architecture.

C++

We consider C++ for tasks where performance, resource control, or integration with existing native systems is critical.

We don't position C++ as a default technology for ordinary websites — whether to use it depends on the specific technical task.

Frontend Technologies

The frontend defines the interface and how users interact with a digital product.

For frontend development, we use:

  • JavaScript;
  • TypeScript;
  • React;
  • Angular;
  • Vue.js.

JavaScript

JavaScript powers interactive frontend functionality, dynamic interfaces, and browser-side logic.

We also maintain and modernize existing projects built on legacy JavaScript and jQuery when a full frontend rebuild isn't necessary.

TypeScript

TypeScript adds static typing to the JavaScript ecosystem and is especially valuable for large applications, complex interfaces, and team development.

We use it both on the frontend and in Node.js backends.

React

React is a good fit for complex interactive interfaces, dashboards, SaaS, customer portals, and other component-based web applications.

Angular

We use Angular for large frontend applications, enterprise interfaces, admin systems, and projects that need a structured application architecture.

Vue.js

Vue.js works for both standalone interactive components and full-scale web applications. It is well suited for dashboards, SaaS, portals, and custom frontends.

Mobile Technologies

For mobile development, we use cross-platform and native-oriented technologies:

  • Flutter;
  • React Native;
  • Kotlin;
  • Dart.

Flutter

Flutter lets us build iOS and Android apps from a shared codebase. It is well suited for business apps, ecommerce, service apps, MVPs, and other cross-platform products.

React Native

React Native brings the React ecosystem to cross-platform mobile development and can be a logical choice when your web team already works with JavaScript or TypeScript.

Kotlin

We use Kotlin primarily for Android development and tasks that require a native mobile implementation.

Dart

Dart is the core language of the Flutter ecosystem. We work with Dart code, packages, and business logic, and support existing Flutter/Dart applications.

No Single Stack Fits Every Product

A corporate website, SaaS, marketplace, high-load service, and mobile app all have different technical requirements. That's why we don't tie every project to a single language or technology stack.

When choosing a stack, we consider:

  • functionality;
  • expected load;
  • time to market;
  • integrations;
  • security requirements;
  • team expertise;
  • maintenance costs;
  • long-term roadmap.

Modernizing an Existing Stack

Not every project needs a rewrite just because a new technology appears. It's often more effective to update dependencies, refactor, optimize the architecture, or replace individual components step by step.

Full-Cycle Development

Promodex can take on not just a single technology but the entire system: UX/UI, frontend, backend, APIs, databases, integrations, mobile development, QA, deployment, and technical support.

Why Promodex

Promodex has been doing web and software development since 2015. We choose technologies based on what the product needs and never overcomplicate the architecture just to use a trendy stack.

Our main criterion: the chosen solution must perform well, be maintainable, and support your business as it grows.
