Back-End Development Services

Our talents will provide you with the best back-end development services, including back-end architecture development, fault-free synchronization, backup, reliable data storage, etc.

What Our IT Company Can Do for You

We can offer you the following back-end development services.

API Layer Development

We're experts at back-end API design and development. Our back-end developers are also competent in API management and segregation, openAPI requirements, implementation of SDKs for external developers, and any other API-related issues affecting interoperability and connectivity.

Back-End Troubleshooting & Optimization

Our engineers take over the development process and add new features, fix defects, and provide additional support services. We know how to do that efficiently in terms of time and cost.

Omnichannel Back-End Development

For many years we have been engaged in the design and development of complex omnichannel solutions. We have production-proven approaches, patterns, and reusable components to build an efficient back end that will be able to communicate with web and mobile applications, terminals & ATMs, VoIP solutions, etc. We deal with multiple back-end technologies and integration types and can advise on the appropriate one for your project at its initial stage. We pay special attention to such aspects of back-end development as scalability, performance, maintainability, and security. We know how to integrate workflow engines, API management solutions, successfully tackle data transformation and management issues.

Back-End Integration Testing

We're competent in planning and execution of stub-based integration testing or integration testing with the whole set of the relevant systems connected. In part, such testing can be embedded into the CI/CD process. We'll show how.

Implementation of Integration Stubs

For independent testing of a system, integration stubs are required that emulate the operation of external systems according to specific algorithms. We have our own know-how for test stub management framework development.

Post-Production Support

Have issues with the back end after the system goes into production? We'll handle it, adding new features and assisting you with technical debt to ensure your system lives a long and healthy life.

Back-End Decoupling

Increase service availability and enjoy more opportunities for parallel development with service decoupling. We implement time and tested methods of back-end decoupling for various industries.

Integration Layer Development

We are experts at integrating with different third-party and in-house systems, APIs of various types, data transformation, connector development, and call orchestration.

Back-End Upgrade

We'll rewrite your code and make the system feel fresh and modern. Upgrade the tech stack, migrate into cloud infrastructure, make architectural and code refactoring to meet the best code quality standards.

Cooperation Models

Managed Team (Team-as-a-Service)

Hire more than just several separate talents. Enjoy a team capable to deliver the expected result, with an established balance of roles and responsibilities and added value competencies.

Team Augmentation

Scale up your team by adding only specific players. Hire a particular talent or several talents for your project. Choose a developer, QA expert, BA, or another talent that your project lacks.

Dedicated Development Center (DDC)

The Dedicated Development Center is literally your development center located on our premises. The DDC has its own dedicated workspace with your logo, separate server facilities, and strict security policies.

Fixed Budget Approach

This approach appeals to those of our clients who need planning of the project budget at the very beginning. For this, you need a detailed specification with a clear deadline and no significant changes planned.

We admit that TaaS is the most cost-effective alternative with the highest overall project KPIs. Yet, we guarantee great cooperation results regardless of your model of choice.

Our Teams

No need for individual staffing. We have already assembled, balanced, and focused engineering teams ready for onboarding.

At least 2 projects in common for every team member

Established team process – task management, quality control, delivery of results, and so on

Team specialization and focus on certain task types

Existing business expertise for certain domains

Service Team Structure

A Service Team (Microteam) is a group of engineers who have already worked together and know how to do certain tasks/projects.

Examples: mobile app team, back-end team, front-end app team, microservice/feature team, and so on.

For bigger projects, we create project teams based on a set of microteams, thus making the entire staffing process easily scalable.

QA, BA, DevOps, and other resources may be part of a microteam or may work as a separate team depending on the project staffing requirements.

We may send you a couple of available team profiles within 3 business hours from your request time.

BeakerX for Jupyter Notebook

Back-end development of a web application for data scientists and engineers. Creating documents with live code, equations, visualizations, and narrative text has never been so easy.

Top Microservice Architecture for Your Backend

The microservice architecture is a de facto standard now for systems that require high availability combined with the flexibility of parallel development by several teams.

That includes such services as:

Back-End Implementation

Implementation of a microservice-based back end (optionally — including microfrontend implementation)

Decoupling into Microservices

Monolyth system decoupling into a microservice architecture (including back end, microfrontend, DB decoupling)

Migration
to Cloud

Migration of the existing system (or the system that is already microservice-based) into cloud microservice infrastructure

Our engineers have several practical years of experience working with microservices, their infrastructure, and tools such as different MQs (Kafka, RabbitMQ, etc.), Docker/Kubernetes, Zabbix, etc. We have successfully completed and are running projects which include microservice implementation for very sensitive systems like e-banking and transaction processing, document management, and healthcare.

Additional Points to Consider

High-Load Support
on the Back End

High-load back-end designing differs significantly from a regular back- end development project. Our architects and developers have all the required skills and abilities to build high-load systems that handle millions of transactions within a short period of time.

Handling Legacy Systems

In some cases, the load which comes through the back end to the external systems should be controlled. Such external systems can be the legacy ones that were not designed to handle such load. To tackle such cases, we use queuing mechanisms and specific caching policies.

External API Development

Any back end should have a specific communication protocol. Our back-end developers are experts at API design, they know inside out how to implement an API management system and are skillful at preparing documentation for external developers.

Integration Points
to External Systems

It is crucial to give a good think about integration points, integration protocols, and rules of data transformation and aggregation. We have a clear vision how to create integration adapters, deal with call orchestration, and much more.

Administration UI

Often a system needs a separate administration console. We have a set of time-proven and reliable components to build an effective administration console (including user management, audit log, permission management, etc.).

Monitoring

Systems may have either embedded monitoring facilities, or they use external ones. Regardless of the execution method, we know how to do it correctly and efficiently.
