Node.js / NestJS
Scalable APIs and microservices
JavaScript on the server, plus NestJS for well-structured applications. We build APIs, microservices, chats and real-time services.
// Backend · 12 technologies
Backend development: Node.js, Python, Go, PHP and Java
The backend is the server side of a product: business logic, data storage, payments and APIs for web and mobile. We choose the language per task — sometimes development speed matters most, sometimes performance under high load or mature libraries for data and AI.
What we build
Server logic, APIs and systems that keep up as load and business grow.
- REST and GraphQL APIs
- Microservice architecture
- Payment and billing systems
- Realtime: chat, notifications, tracking
Business outcome
stable performance under load and secure data.
Technologies and what we build with them
Express
Fast, lightweight servers
A minimalist web framework for Node.js. Suits lightweight APIs, webhooks and small services.
Python / FastAPI
High-performance APIs and AI services
Python with the modern FastAPI framework. We build fast APIs and services for AI and data processing.
Django
Robust web platforms with admin
A Python framework with a built-in admin. We use it for robust web platforms, portals and internal systems.
Go
High-load, fast services
A compiled language from Google. We choose Go for high-load services where speed and resource efficiency matter.
PHP / Laravel
Web services and CRM systems
PHP with the Laravel framework. We quickly build web services, CRM systems and portals, and maintain existing PHP projects.
Java / Kotlin Spring
Enterprise and fintech systems
The Java and Kotlin enterprise ecosystem. We use it for corporate, banking and fintech systems.
.NET
Enterprise solutions in C#
Microsoft’s C# platform. We build enterprise solutions and Microsoft ecosystem integrations.
GraphQL
Flexible APIs for web and mobile
A query language for APIs. It gives frontends and mobile apps exactly the data they need in one request.
WebSockets
Realtime chat and updates
A persistent connection protocol. We build chats, notifications, tracking and live updates without page reloads.
Kafka / RabbitMQ
Queues and event processing
Message brokers. We build job queues and event processing so systems stay up under peak load.
gRPC
Fast service-to-service calls
A fast protocol for service-to-service communication. We use it in microservice architectures.
