Backend development services
We build server-side software that can withstand growth and peaks. Our code is readable and tested, releases are stable, and data is protected.
Backend development services
We’ve compiled the key backend development service types we provide, from architecture to operations. Any block can be used separately or included in the project.
Architecture and technical design
We select an approach, draw a diagram, assess risks, and plan for growth.
Databases
We model data, configure indexes and backups, and perform migrations without downtime.
Application Interfaces (APIs)
We design interfaces, manage versions, document errors, and provide OpenAPI specifications.
Microservices development
We carefully split the monolith, add an API gateway, and maintain backward compatibility.
Performance and scaling
We profile, cache, and balance traffic. In the cloud, we enable autoscaling.
Cloud and infrastructure as code
We deploy in AWS, Azure, or GCP. Containers, Kubernetes, Terraform—everything is reproducible.
Migrations and data processing
We migrate databases and services, check data quality, and maintain a rollback plan.
Backend testing
We write unit, integration, and end-to-end tests. We block the release in case of failure.
Security and compliance
We encrypt data, manage access and secrets, and audit actions.
Integrations
We connect payments, CRM, and providers. We implement queues and retries for resilience.
Continuous integration and delivery
We automate builds, tests, and deployments. Releases are predictable and reversible.
Support and development
We monitor production, fix incidents, and improve them step by step and according to plan.
Core tech stack we work with
We use proven stacks and tools. We select solutions based on workload, team, and required integrations.

Challenges our backend developers solves
Backend development removes typical barriers to growth and stability. See what problems we solve in real projects.
Slow releases
Contract APIs and automated tests shorten the cycle from idea to release. CI/CD eliminates manual steps and reduces the risk of errors in releases.
Load drops
Caches and queues mitigate peaks and stabilize responses under load. Autoscaling adds capacity on time and protects against downtime during peaks.
Slow API responses
We profile code and fix requests, reducing p95 and p99 latency. Indexes and cache significantly speed up heavy selections and repeated requests.
Fragile integrations
We fix message contracts and explicitly consistent data schemas between systems. We enable retries and idempotency to eliminate duplicates and write races.
Data disorder
We introduce a unified data schema and ensure input types are always checked. We normalize units and timestamps, reducing errors in analytics reports.
Complex migrations
We break the process down into steps and set time-based checkpoints. We launch migrations without downtime and have a rollback plan ready.
High cloud bills
We remove excess resources and adjust storage and data traffic parameters. We enable autoscaling and scheduling to pay only for the actual workload.
Leaks and access risks
Roles and attributes reliably limit permissions and visibility of sensitive data. Encryption and auditing reduce damage and speed up the investigation of serious incidents.
Lack of operational visibility
We provide metrics and traces, and build a dashboard with key service indicators. Logs and event chaining help identify the cause and fix it faster.
Difficulty in scaling
We create a modular structure with clear boundaries and independent component releases. We move hotspots to separate services and reduce the risk of outages.
Many manual operations
We implement CI/CD and automate pre-release checks to reduce errors. We migrate infrastructure to code and remove routine tasks from daily processes.
Contractor dependency
We write clear code and maintain well-organized, up-to-date documentation. We make interfaces open to ensure easy replacement or expansion.

Recent software we made
The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions.
They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.
Nectarin LLC aimed to develop a complex Ruby on Rails-based platform, which would be closely integrated with such systems as Google AdWords, Yandex Direct and Google Analytics.
I was impressed by SumatoSoft’s prices, especially for the project I wanted to do and in comparison to the quotes I received from a lot of other companies.
Also, their communication skills were great; it never felt like a long-distance project. It felt like SumatoSoft was working next door because their project manager was always keeping me updated. Initially.
We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us.
SumatoSoft is great in every regard including costs, professionalism, transparency, and willingness to guide. I think they were great advisors early on when we weren’t ready with a fully fleshed idea that could go to market.
They know the business and startup scene as well globally.
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality.
Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.
Together with the team, we have turned the MVP version of the service into a modern full-featured platform for online marketers. We are very satisfied with the work the SumatoSoft team has performed, and we would like to highlight the high level of technical expertise, coherence and efficiency of communication and flexibility in work.
We can say with confidence that SumatoSoft has realized all our ideas into practice.
The Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.
SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly.
SumatoSoft succeeded in building a more manageable solution that is much easier to maintain.
From the early stages of the project, SumatoSoft demonstrated a proactive attitude, actively seeking opportunities to enhance the solution and anticipate our needs. They consistently took the initiative to address any potential issues, provide timely updates, and offer solutions to challenges that arose during development. This proactiveness greatly contributed to the project’s success and exceeded our expectations.
SumatoSoft is flexible, efficient, and extremely good at planning and being proactive. They have also been very proactive in their approach throughout the project, seeking to understand the needs and the reasons behind them before launching into development, which has been helpful for maintaining direction and consistency, especially because the end client is regularly generating new ideas for added features.

Frequently asked questions
What is backend development?
Backend development is the server-side portion of an application that processes requests and data. It handles business logic, authorization, integrations, and returns results to the user interface.
What is enterprise backend development?
An enterprise backend is a server designed for large companies with high workloads and complex processes. It takes into account security, auditing, fault tolerance, legal requirements, and internal policies. Such projects include integrations, migrations, access management, and strict response time SLAs.
What is the difference between a backend and a frontend?
The frontend is the interface that the user sees and interacts with. The backend is the server that processes requests, stores data, and executes logic. They communicate via an API: the frontend makes requests, and the backend returns a response quickly.
How much does backend development cost?
The cost depends on the scope, integrations, security requirements, and the project team. We work on a fixed price per stage or on a time-and-materials basis. We provide an estimate after a short discussion and a template of project requirements and risks.
What are the key components of the backend?
The main parts are: architecture, data model, databases and cache, API, and integrations. Security, testing, monitoring, logging, infrastructure, and automated deployment are also important.
