API Gateway & Middleware

Connect Everything
Legacy Systems to Modern Services

We build integration platforms that connect disparate systems, modernize legacy applications, and enable microservices architectures—with security, rate limiting, transformation, and orchestration built in.

Benefits of Centralized Integration

Modern enterprises run dozens of systems—SaaS tools, legacy applications, databases, and microservices. API gateways and middleware create a unified integration layer that simplifies connectivity and enforces policies.

System Integration

Connect CRM, ERP, billing, support, and custom applications through a unified API layer—reducing point-to-point integrations from N² to N.

Legacy Modernization

Expose legacy systems through REST or GraphQL APIs without rewriting them. Modernize frontends while preserving battle-tested business logic.

Microservices Enablement

Centralized authentication, rate limiting, request routing, and service discovery for microservices architectures.

Rate Limiting & Security

API keys, OAuth, rate limiting, DDoS protection, and payload validation enforced consistently across all backend services.

How We Build Integration Platforms

01

Integration Inventory

Map all systems, APIs, data sources, and integration points. Identify patterns, bottlenecks, and opportunities for consolidation.

02

Gateway Architecture Design

Design API gateway topology, routing rules, authentication flows, and transformation logic. Choose between Kong, Apigee, AWS API Gateway, or custom solutions.

03

Middleware Implementation

Deploy message queues, event streams, ETL pipelines, and service mesh as needed. Implement data transformation and protocol translation.

04

Security & Policy Enforcement

Configure authentication, authorization, rate limiting, request validation, and monitoring. Implement API versioning and deprecation policies.

05

Monitoring & Analytics

Deploy API analytics, error tracking, performance monitoring, and usage dashboards. Set up alerts for failures and threshold breaches.

Integration Solutions We Build

Legacy System Integration

Wrap SOAP, XML-RPC, or proprietary protocols in modern REST APIs. Enable legacy mainframe or ERP systems to participate in microservices architecture.

Microservices Gateway

Kong, Apigee, or AWS API Gateway managing authentication, rate limiting, routing, and observability for hundreds of microservices.

Third-Party API Aggregation

Unified interface for Stripe, Salesforce, SendGrid, Twilio, and other SaaS APIs with caching, retry logic, and fallback handling.

Event-Driven Architectures

Kafka, RabbitMQ, or AWS EventBridge for asynchronous communication between services with guaranteed delivery and replay capabilities.

Data Integration Pipelines

ETL workflows moving data between databases, data warehouses, and SaaS applications with transformation and validation.

Backend-for-Frontend (BFF)

Custom API layers optimized for mobile apps, web clients, or IoT devices with tailored payloads and caching strategies.
