Our Expertise
What We Build
From API design to cloud deployment, we build backend systems that scale with your business.
Custom API Development
REST, GraphQL, gRPC, WebSocket APIs with comprehensive documentation, versioning, and rate limiting for web, mobile, and third-party integrations.
Microservices Architecture
Distributed systems design, service mesh implementation, event-driven architecture, and domain-driven design for scalable enterprise platforms.
AI & LLM Backends
RAG pipelines, vector database integration, model serving infrastructure, AI agent orchestration, and LLM API management for intelligent applications.
Cloud-Native Solutions
AWS, GCP, Azure deployment, serverless architectures, containerization with Docker, Kubernetes orchestration, and infrastructure as code.
Database Architecture
PostgreSQL, MongoDB, Redis, DynamoDB design and optimization, data modeling, indexing strategies, replication, and backup automation.
Authentication & Security
OAuth 2.0, SSO, RBAC, JWT token management, encryption at rest and in transit, security audits, and compliance implementation (GDPR, SOC 2).
Real-Time Systems
WebSockets, Server-Sent Events, pub/sub messaging, live dashboards, collaborative features, and real-time data synchronization.
Legacy Modernization
Monolith to microservices migration, cloud platform transitions, re-architecture for scalability, and gradual system modernization.

Our Process
How We Deliver
A structured approach to backend development, from architecture to production.
Discovery & Architecture
We analyze your requirements, define technical scope, assess existing infrastructure, and design system architecture with scalability, security, and performance in mind.
Technical Design
We create API specifications, database schemas, service diagrams, technology recommendations, and a detailed technical roadmap with milestones.
Sprint Planning
We break down development into 2-week sprints, define deliverables, set up dev/staging/production environments, and establish CI/CD pipelines.
Development & Testing
We build backend services with comprehensive unit, integration, and load testing, code reviews, security scanning, and weekly progress demos.
Deployment & Launch
We deploy to production with zero-downtime strategies, monitoring setup, performance optimization, documentation handover, and team training.
Support & Optimization
We provide post-launch support, performance monitoring, bug fixes, security updates, and ongoing optimization based on real-world usage.

FAQ
Frequently Asked Questions
What's included in backend development services?
Our backend development services include system architecture design, API development (REST/GraphQL/gRPC), database design and optimization, authentication and security implementation, cloud deployment (AWS/GCP/Azure), CI/CD pipeline setup, monitoring and logging, load testing, documentation, and post-launch support. We deliver production-ready, scalable backend systems from design to deployment.
How much does custom backend development cost?
Pricing varies based on scope and complexity. MVP projects start from $8K (4-8 weeks), growth platforms from $25K (8-16 weeks), and enterprise solutions are custom-priced based on requirements. We offer both fixed-price and time-and-materials models with transparent weekly reporting and budget tracking. Contact us for a detailed proposal based on your specific needs.
How long does backend development take?
Timelines depend on project complexity. A single API or microservice takes 4-8 weeks, a full backend system takes 8-16 weeks, and enterprise platforms with multiple microservices take 16+ weeks. We work in 2-week sprints with regular demos and can adjust scope to meet launch deadlines. We provide a detailed timeline after the discovery phase.
Do you provide ongoing maintenance after launch?
Yes. All projects include post-launch support (2 weeks to 1 month depending on the plan). We also offer ongoing maintenance contracts covering monitoring, security updates, performance optimization, bug fixes, and feature enhancements. Enterprise clients can opt for dedicated support teams with SLA guarantees (99.9% uptime).
What's the difference between backend development services and hiring developers?
Backend development services are project-based: we deliver a complete backend solution (architecture, code, deployment, documentation) with a defined scope, timeline, and budget. Hiring developers means bringing individual engineers onto your team for ongoing work. Services are best for specific projects or MVPs, while hiring works for long-term product development. We offer both models.
Can you work with our existing frontend team?
Absolutely. We frequently collaborate with in-house or external frontend teams. We provide comprehensive API documentation, OpenAPI/Swagger specs, webhook integrations, and regular sync meetings. Our developers work in your preferred communication channels (Slack, Teams) and can adapt to your existing workflows, repositories, and deployment processes.
