01
Enterprise System Integration
Connect ERP, CRM, finance, logistics, HR, operational and custom platforms through defined interfaces and integration workflows that preserve process continuity across systems.
Enterprise Integration & API Engineering
Connect Systems. Unify Data. Build APIs That Scale.
We engineer the integration layer between enterprise applications, data platforms, partners and digital channels — creating secure, governed and observable connections that keep information and business processes moving reliably.
System Integration & APIs
Enterprise systems create more value when they operate as one connected environment.
Integration is the connective layer between applications, data and business processes.
Without a deliberate architecture, organisations accumulate point-to-point dependencies, duplicated data, manual handoffs and interfaces that become difficult to change safely.
Malayan designs and engineers integration solutions that connect modern applications, legacy platforms, cloud services, data stores and external partners through stable interfaces and controlled information flows.
The architecture is shaped by business criticality, transaction patterns, security boundaries, data ownership and change frequency — so the integration model supports both current operations and future platform evolution.

Core Integration Capabilities
Four foundations for connected enterprise systems.
We cover the architecture and engineering required to expose capabilities safely, move data reliably and reduce brittle dependencies between systems.
02
API Engineering & Management
Design and implement internal, partner and customer-facing APIs with clear contracts, lifecycle controls, authentication, versioning and documentation.
03
Data & Event Integration
Move and synchronise information using request-response, messaging, event-driven and scheduled patterns selected according to latency, consistency and resilience requirements.
04
Legacy & Partner Connectivity
Bridge older applications and external ecosystems without forcing immediate replacement — using adapters, gateways and controlled interfaces to isolate complexity and reduce coupling.
Integration Architecture
How systems, APIs and data connect through one governed integration fabric.
The architecture separates business systems from the connectivity layer so interfaces can evolve without every application becoming directly dependent on every other application.
From fragmented applications to governed enterprise connectivity.
A clear integration layer creates reusable interfaces, controlled data movement and better visibility into how transactions cross system boundaries.

Cross-Cutting Layer
Governance & Operations across every integration boundary.
Controls apply across systems, interfaces and services rather than appearing only at the end of the transaction flow.
Identity & AccessMonitoring & TraceabilityVersioning & Change ControlSecurity & Data Boundaries
Operational feedback loop: interface health, failures, latency and usage signals feed back into API and integration decisions so bottlenecks and fragile dependencies can be addressed deliberately.
Integration Patterns
The right connectivity model for each business interaction.
Not every integration should behave the same way. We select patterns according to transaction criticality, response time, data volume, system ownership and tolerance for temporary failure.
Real-Time APIs
Immediate request-response interfaces for transactions and digital experiences that depend on a direct answer between systems.
Event-Driven Integration
Loosely coupled event flows that propagate business changes without forcing every consuming system into a direct dependency.
Data Synchronisation
Controlled movement and reconciliation of reference, transactional and reporting data where consistency and ownership must remain explicit.
B2B & External Connectivity
Secure interfaces for customers, suppliers, platforms and ecosystem partners with explicit authentication, validation and boundary controls.
Architecture principle
We avoid creating a new integration problem while solving an old one. Interfaces are designed to reduce unnecessary coupling, keep ownership clear and make change safer across the wider platform.
API & Integration Governance
Connectivity with controlled access, contracts and change.
Enterprise integration needs clear rules around who can connect, what data can move, how interfaces evolve and how failures are traced across system boundaries.
Identity & Access
Authentication, authorisation and trust boundaries are designed around the systems and parties allowed to call each interface.
API Contracts & Versioning
Defined request, response and compatibility rules reduce unexpected breakage as applications and consumers change over time.
Data & Boundary Controls
Validation, transformation and exposure rules keep sensitive or system-specific data from moving across boundaries without purpose.
Observability & Traceability
Logs, metrics, correlation and failure visibility help teams understand how transactions move across distributed services.
Delivery Approach
A controlled path from system landscape to production integration.
The delivery model starts with business flows and system dependencies, then moves through target architecture, interface engineering, validation and controlled transition.
01 · Discover
Map systems and business flows.
Identify applications, interfaces, data owners, business processes, dependencies, pain points and operational constraints.
02 · Architect
Define the integration model.
Select interaction patterns, integration boundaries, API contracts, security controls and the target connectivity architecture.
03 · Engineer
Build interfaces and flows.
Implement APIs, adapters, transformations, events and orchestration around the agreed contracts and ownership model.
04 · Validate
Test behaviour across boundaries.
Validate functional flows, failure handling, security, performance, data consistency and downstream impact before release.
05 · Transition
Release with operational visibility.
Document interfaces, ownership and support paths, then transition the integration layer with monitoring and change controls in place.
Representative Engagement Areas
Where System Integration & APIs creates enterprise value.
These examples illustrate common integration problems the practice is designed to address. They are representative scenarios, not claims of specific client deployments.
ERP & Business Application Integration
Connect operational platforms with CRM, finance, HR, warehouse, transport or other business systems while keeping ownership and transaction boundaries clear.
Partner & Platform APIs
Expose controlled services to customers, vendors, payment providers, logistics partners or external platforms without opening internal systems directly.
Legacy System Modernisation
Introduce stable interfaces around older platforms so new applications can connect without requiring immediate replacement of the underlying system.
Cross-System Data Synchronisation
Coordinate master, transactional and reporting data across applications to reduce duplicate entry, conflicting records and manual reconciliation.
Connect, Modernise or Expose
Three System Integration & APIs pathways.
An engagement can begin with a new integration foundation, an existing environment that needs to be untangled, or business capabilities that need to be exposed safely to new channels and partners.
