What We Do

Backend Capabilities We Deliver

From APIs to databases — full-stack server-side engineering

REST API Development

Design and build clean, versioned, and well-documented RESTful APIs that power web, mobile, and third-party integrations.

Microservices Architecture

Decompose monoliths into independently deployable microservices for scalability, maintainability, and faster release cycles.

Database Design & Management

Architect efficient relational (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) databases optimized for your scale.

Authentication & Authorization

Implement OAuth2, JWT, SSO, and role-based access control systems to secure your app and user data end-to-end.

GraphQL API Development

Build flexible, efficient GraphQL APIs that give clients exactly the data they need — reducing over-fetching and under-fetching.

Background Jobs & Queuing

Implement async processing, job queues (BullMQ, Celery, RabbitMQ), and scheduled tasks for high-throughput operations.

FAQs

Frequently Asked Questions

What backend technologies do you specialize in?

We specialize in Node.js, Python, Java, .NET, and Go. Our framework expertise includes Express, FastAPI, Spring Boot, and Django. We choose the best stack based on your project's scalability, performance, and team familiarity requirements.

How do you ensure backend security?

Security is built into every layer: input validation, parameterized queries, JWT/OAuth2 authentication, encryption at rest and in transit, OWASP Top 10 mitigation, and regular penetration testing before deployment.

Can you migrate our legacy backend to a modern stack?

Yes. We specialize in legacy modernization — from monolith-to-microservices migration, database upgrades, and API layer creation to full re-architecture using modern cloud-native stacks with zero-downtime transition strategies.

Do you provide API documentation?

Absolutely. Every API we build comes with comprehensive Swagger/OpenAPI documentation, Postman collections, integration guides, and clear versioning strategies for long-term maintainability.

What's the difference between monolithic and microservices architecture?

A monolith is a single codebase handling all functionality — simpler to start but harder to scale. Microservices split your application into independent services that can be developed, deployed, and scaled separately. We help you choose the right approach based on your team size, traffic, and growth plans.
