Back-end

What is a backend?

The backend is the foundation of any digital product, ensuring its stability, security, and performance. It's under the hood where the service's logic and integration are built, and where data and requests are processed. A powerful server foundation allows for easy product development, risk-free launch of new features, and the ability to withstand high loads.

When to hire a backend developer

A back-end developer is a specialist responsible for the server side of an application or website. They design the architecture, manage databases, create and integrate APIs, and ensure stable system operation under high loads.

Hiring a backend developer may be necessary at any stage of a product's development, from creation from scratch to further development.

• When developing a website, CRM/ERP system, mobile app, or SaaS service, a backend developer designs the architecture, configures databases, and is responsible for ensuring proper interaction between system components.
• When the number of users or the volume of data rapidly grows, the backend developer optimizes performance, implements caching, and ensures system stability even with thousands of simultaneous requests.
• To exchange data with external platforms —payment systems, marketplaces, CRM, ERP, and analytics—he configures secure and reliable connections. We can develop and implement any API and integration for new and existing projects. You can order a turnkey online store with a CRM module and configurator or a CRM with a chat interface and AI bot.
• When migrating or modernizing a legacy system, a backend specialist will help transfer data, update the stack, optimize code, and implement modern approaches to eliminate architectural limitations.
• To enhance data security, it prevents vulnerabilities, protects information from unauthorized access, configures encryption, user rights control, and backups. The backend is the first line of data protection.
• When building complex business logic, if your product has atypical scenarios—for example, a multi-level permissions system, complex calculations, or automated processes—it is the backend that is responsible for their implementation and the consistency of all modules.

Backend technologies and tools

AVADA MEDIA's backend team works with modern programming languages and frameworks, selecting the optimal technology stack for each project – from MVPs to corporate CRM with a 2D/3D configurator and scalable SaaS platforms.

Python Backend Developer

Python is ideal for building flexible web platforms, internal corporate systems, and services with AI integration. Our developers use Python frameworks like Django, Flask, and FastAPI to quickly build scalable applications with a well-designed architecture and clean code, easily integrating machine learning algorithms and analytics tools. This stack ensures our products remain stable, ready for growth and change.

In the DF-platform project for the international crowdfunding platform Definder, AVADA MEDIA backend developers created a Python backend using the Fast API, providing transaction processing, secure data storage, user registration and authorization, and investment project management through an admin panel.

Java Developer

Java is commonly used to build platforms where stability and security are critical. Using Spring and Hibernate, backend developers at AVADA MEDIA create complex systems for financial institutions, logistics companies, and large enterprises.

For example, when developing a CRM for roofing and fencing components manufacturer FOROSTINA, our backend developers built the server side in Spring (Java), ensuring order processing, data security, and customer, inventory, financial, and HR management. The scalable architecture allowed for a smooth migration from the previous out-of-the-box system and the creation of a reliable platform for business growth.

This stack allows for the development of modular programs that are easily scalable and can handle high loads, and integrate with ERP, CRM, and internal company services. To ensure a reliable and stable infrastructure, even with high traffic volumes, you should hire a Java developer.

PHP Developers for Hire

PHP programming services are required for the creation of online stores, SaaS platforms, and corporate portals. AVADA MEDIA developers use modern PHP frameworks such as Laravel, Yii2, and Symfony to build platforms with intuitive control panels, user-friendly APIs, and high performance. We recommend hiring PHP developers if you require a quick launch, easy support, and integration with external services.

For the QSS project our backend developer built a robust server architecture using PHP (Laravel) and Java to ensure secure data storage, request processing, official document generation, inspection process management, data synchronization between the mobile and web apps, and an authorization and access control system for employees and administrators. We also offer a Yii2 developer for internal management systems, such as employee and project accounting with a user-friendly admin panel.

Node.js developer

Node.js is an excellent choice for dynamic, high-load systems that process a large number of real-time requests (such as chats, analytics panels, and APIs). For such solutions, our backend developers use popular frameworks:

• Express.js – for rapid development of server logic and APIs;
• NestJS – for complex systems with modular architecture and easy scaling;
• Next.js, which allows you to combine frontend and backend in a single application, providing server-side rendering and powerful capabilities for web platforms.

The Node.js backend easily adapts to various tasks – from developing microservice architectures to complex enterprise platforms. It allows you to combine multiple services into a single ecosystem, quickly implement updates, and effectively distribute the load between components. This gives businesses a flexible server infrastructure ready for growth without downtime.

Databases and infrastructure

Depending on the project's structure and scale, we select the optimal solution for specific tasks. To create systems with a clearly structured data structure and complex transactions, our backend specialists work with relational databases such as PostgreSQL, MySQL, and MariaDB.

If a software solution requires high-speed processing of large volumes of heterogeneous data or flexibility in data structure, it's better to use NoSQL storage solutions such as MongoDB, Redis, or Elasticsearch. We use this stack to build analytics platforms, real-time services, and projects with dynamic workloads.

Our backend specialists use Docker and Kubernetes containerization tools for deployment and maintenance, while CI/CD processes help quickly implement updates without disruption. Cloud solutions from AWS, Google Cloud, and Azure provide flexible scaling, while integrations via REST, GraphQL, and WebSocket ensure seamless interaction between all platform components.

How to choose a backend developer?

When hiring a backend developer, we recommend paying attention to the following professional and personal qualities.

• Technical skills and a professional approach. A specialist must not only be able to work with the technology stack but also select the right tools for the task, translate complex requirements into secure and effective solutions, build a scalable architecture, and optimize performance.
• Teamwork and communication. A developer must be able to justify their decisions, interact effectively with colleagues and managers, provide constructive feedback, and be mindful of the company's business goals.
• Responsibility and attention to detail. A backend developer works with key logic and data, so mistakes can be costly. It's important for a specialist to analyze tasks, find optimal solutions, and not simply follow instructions.
• Proactivity and development. Technology is constantly changing, and an experienced developer quickly masters new tools, suggests improvements, and anticipates potential issues, helping the product evolve.

Proven experience is critical when hiring a backend developer. Real projects in AVADA MEDIA portfolio confirm the expertise of our specialists.
