System integration
Systems that agree with each other.
REST and SOAP APIs, webhooks, file and SFTP exchanges, event-driven architectures and middleware connecting ERP, CRM, payment, banking and SaaS systems, with monitoring that tells the business what failed.
- Idempotent writes everywhere
- Business identifiers in every log line
- Dead-letter queue, never silent drop
- Contracts versioned and documented
- Reconciliation as a pipeline step
Overview
How we approach it.
Most integration estates decay: built quickly, no error handling, nobody knows which flow failed last night. We build integrations like production software, with typed contracts, idempotent writes, retries, dead-letter queues and alerts routed to the people who can act on them.
Technologies we reach for
- Node.js
- Python
- Java
- REST APIs
- GraphQL
- AWS
- Oracle Cloud (OCI)
- PostgreSQL
- Docker
What we deliver
Capabilities
Everything Amrelia Technologies designs, builds and runs under Integration.
REST & SOAP APIs
Consuming and exposing APIs with authentication, versioning, throttling and documentation.
Webhooks & events
Event-driven architectures with queues and streams so systems react in near real time without polling.
File & SFTP integrations
Bank files, payroll, EDI and bulk loads: parsing at scale, encryption, archiving and reconciliation.
ERP & CRM integrations
Oracle, SAP, NetSuite, Dynamics, Salesforce and HubSpot through supported APIs, never table-level hacks.
Payments & banking
Payment processors, settlement files, ISO 20022 and bank connectivity with the controls finance needs.
SaaS & middleware
Point-to-point where it is honest, an integration layer where the estate has outgrown it: OIC, MuleSoft, custom Node.js.
Integration monitoring
Business identifiers on every message, dashboards per flow, alerts with the record and the fix.
Reliability patterns
Idempotency keys, retries with backoff, dead-letter handling, replay tooling and reconciliation reports.

Related services
Enterprise Application Development
Internal applications, employee portals, operations dashboards, approval systems, ERP extensions and reporting tools, built with enterprise security and integration requirements treated as core scope.
Workflow Automation
Intake, routing, approvals and hand-offs automated end to end, with people where judgment is needed.
Cloud & DevOps
Cloud architecture, containers and serverless, CI/CD, observability and infrastructure as code on Vercel, AWS, Azure or OCI, so releases are boring and outages are rare and short.
Solutions we build with it
Two systems that never quite agree?
That is an integration design problem, and it is fixable. Tell us which two.
