Overview

What We Deliver

Modern businesses run on dozens of interconnected systems, from CRM and ERP to payment gateways and third-party SaaS tools. Our integration engineering practice designs the connective tissue that allows these systems to exchange data reliably, securely, and in real time. We build APIs that are a pleasure to consume, event-driven architectures that decouple systems for resilience, and iPaaS solutions that empower business teams to create their own integrations.

Every integration we build follows API-first design principles with comprehensive documentation, versioning strategies, and rate limiting. We implement contract testing, circuit breakers, and dead-letter queues to ensure that failures in one system do not cascade across your ecosystem. The result is a composable, extensible technology platform that adapts quickly to new business requirements.

  • API-First Design

    OpenAPI specifications, contract-first development, and developer portals that make your APIs easy to discover and consume.

  • Event-Driven Architecture

    Asynchronous messaging with Kafka, RabbitMQ, or SNS/SQS for loosely coupled, resilient system communication.

  • iPaaS & Low-Code

    Managed integration platforms that enable business teams to build and maintain their own data flows without engineering support.

  • API Security

    OAuth 2.0, JWT, rate limiting, and API gateway policies that protect your services without sacrificing developer experience.

Capabilities

What Sets Us Apart

Well-designed REST and GraphQL APIs with pagination, filtering, and real-time subscriptions for modern client applications.

Apache Kafka and cloud-native messaging for real-time data distribution, CQRS, and event sourcing patterns.

Bi-directional integrations with Salesforce, SAP, HubSpot, Stripe, and hundreds of other enterprise systems.

Real-time and batch data sync between systems with conflict resolution, transformation, and audit logging.

Centralised API gateways with traffic management, analytics, developer portals, and lifecycle management.

Adapters and middleware that connect legacy systems via modern APIs without requiring changes to existing codebases.

Our Approach

How We Execute

01

Integration Mapping

We document all systems, data flows, and integration points to create a comprehensive map of your current and desired state.

02

API & Contract Design

OpenAPI specs, event schemas, and data contracts are designed collaboratively and validated with all stakeholders before implementation.

03

Build & Test

Integrations are developed with contract testing, comprehensive error handling, and circuit breakers for production resilience.

04

Deploy & Monitor

API analytics, health dashboards, and alerting ensure integrations perform reliably with full visibility into data flow health.
