APIs for web & mobile
REST and GraphQL APIs with documentation, auth and versioning.
// Backend & high load
Backend development and high-load systems
The server side your product runs on: APIs for web and mobile, payments, real-time updates and data processing. We design it to handle user growth without a rewrite.
What we build
Microservices
Breaking up monoliths, event queues and reliable service communication.
High load
Caching, horizontal scaling and query optimization for peak traffic.
Payment systems
Billing, subscriptions, user balances and transaction reconciliation.
Real-time
Chats, notifications, tracking and live updates over WebSockets.
Refactoring & speed-up
Performance audits, bottleneck removal and migration to a modern stack.
Technologies
How we work
- 01
Architecture
Data model, service boundaries, load and security requirements.
- 02
Development
APIs, business logic, tests and documentation.
- 03
Load testing
We test the system under peak traffic before launch.
- 04
Launch & monitoring
CI/CD, logs, metrics and alerts so you see issues before users do.
Timeline and cost
Cost depends on business-logic complexity and load requirements. For existing systems we start with an audit that shows what delivers the biggest impact for the least money.

- Amount of business logic
- Expected load and peak traffic
- External system integrations
- Security and audit requirements
- Real-time features
- Migration of existing data
FAQ
Which language do you choose for the backend?
It depends on the task: Node.js for APIs and real-time, Go for high load, Python for data and AI, PHP/Laravel for fast web services.
Will the system handle growth?
We build scaling into the architecture and verify it with load tests before launch — not after the first traffic spike.
Can you work on an existing backend?
Yes. We start with a code and architecture audit, fix critical issues and continue development.
How do you protect data?
Encryption, access control, protection against common attacks, regular backups and audit logging.
