API Development
High-performance REST & GraphQL APIs using Node.js, NestJS, Golang, and secure microservice communication. We enable seamless integration across platforms.
Overview
APIs are the backbone of modern software systems, enabling seamless integration between applications, services, and platforms. We design and build high-performance APIs that are secure, scalable, and developer-friendly.
Whether you need RESTful APIs for traditional integrations or GraphQL for flexible data querying, we implement best practices including proper authentication, rate limiting, versioning, and comprehensive documentation.
Our APIs are built for reliability with proper error handling, monitoring, and performance optimization. We ensure your APIs can handle growth from hundreds to millions of requests per day.
Key Benefits
Fast and secure APIs
GraphQL or RESTful designs
Easy third-party integrations
Modernization Journey
API Strategy & Design
Collaborating with your stakeholders to define endpoints, data models, and specialized usage patterns using OpenAPI or GraphQL schemas.
Security & Auth Architecture
Implementing Zero Trust principles, including robust OAuth2/OIDC flows, JWT validation, and granular scope-based access controls.
High-Performance Engineering
Developing lightning-fast, stateless services in Node.js or Golang, optimized for low latency and high-throughput concurrent requests.
Testing & Documentation
Generating interactive Swagger/Postman documentation and building automated test suites that guarantee 100% contract compliance.
Scaling & Monitoring
Deploying to production with multi-layer caching, rate limiting, and deep observability (Prometheus/Grafana) for 24/7 reliability.
Use Cases
Mobile app backends

Microservices communication
Technical Pillars
Strategic solutions engineered to resolve legacy complexity and unlock modern performance.
Enterprise API Gateways
Centralizing traffic management, security enforcement, and cross-cutting concerns for high-scale microservices ecosystems.
GraphQL Implementations
Providing a flexible, single-endpoint interface that allows your frontends to query exactly the data they need with zero overfetching.
Legacy Systems Exposure
Building modern API wrappers around fragile legacy backends to enable digital transformation without risky system re-writes.
Microservices Connectivity
Orchestrating high-performance inter-service communication using gRPC or message queues for eventual consistency at scale.

Frequently Asked Questions
REST vs GraphQL - which should I choose?
REST is simpler, widely understood, and great for straightforward CRUD operations. GraphQL offers more flexibility, reduces over-fetching, and is ideal when clients need different data shapes. We can help you choose based on your specific requirements and team expertise.
How do you secure APIs?
We implement OAuth 2.0 or JWT-based authentication, API keys for service-to-service communication, rate limiting to prevent abuse, input validation, HTTPS encryption, CORS policies, and regular security audits.
How do you handle API versioning?
We use URL versioning (e.g., /v1/, /v2/) or header-based versioning, maintain backward compatibility when possible, provide clear deprecation notices, and comprehensive migration guides for breaking changes.
Do you provide API documentation?
Yes, we provide comprehensive, interactive documentation using Swagger/OpenAPI or Postman. This includes endpoint descriptions, request/response examples, authentication details, and a sandbox for testing.
How do you handle high concurrency in APIs?
We implement multi-layer caching with Redis, utilize load balancers for horizontal scaling, and optimize database queries to ensure sub-second response times even during peak traffic surges.
Can you build public-facing APIs for integration partners?
Absolutely. We design developer-friendly public APIs with self-service keys, detailed usage quotas, and comprehensive sandboxes to help your partners build on your platform with ease.
What is your experience with real-time data streaming APIs?
We build low-latency real-time systems using WebSockets, Server-Sent Events (SSE), and gRPC streams, ideal for live dashboards, chat applications, and high-frequency data feeds.
How do you ensure data integrity during API updates?
We utilize database transactions and rigorous schema migrations. Our CI/CD pipeline includes breaking-change detectors to ensure that updates never corrupt existing data or disconnect older client versions.
Do you help with third-party API integrations?
Yes, we have deep experience integrating systems like Stripe, Salesforce, Odoo, and SAP. We build custom middleware that handles complex webhooks, data mapping, and robust error recovery.
How do you monitor API health and performance?
We implement 24/7 observability using Prometheus and Grafana, tracking 'The Four Golden Signals': Latency, Traffic, Errors, and Saturation, ensuring proactive issue resolution before users are affected.
