Backend Development
RaysanDev builds the server side of business software for organisations in Saudi Arabia and the GCC: databases and data models, business logic, secured APIs, integration layers between existing platforms, and the background jobs that keep everything in step.

How we solve it
One data model that everything reads from, business rules applied in one place instead of repeated in every screen, APIs with a documented contract, and integrations that retry, log and alert when an external system fails — because eventually it will.
This is the layer under the web applications we build, and equally the layer that connects platforms you already run, such as Odoo ERP and Bitrix24.
What we build
Versioned, documented, authenticated interfaces for web apps, mobile apps and partners.
Relational data models, indexing, constraints and migration paths that survive growth.
Pricing, eligibility, approvals and calculations implemented once and reused everywhere.
ERP, CRM, LMS, accounting and messaging kept consistent through APIs and webhooks.
Mapping, queuing, retries and error handling between systems that were never designed to meet.
Scheduled jobs, imports, exports, document generation and notification pipelines.
Users, roles, single sign-on and record-level access enforced server side.
Aggregations and read models so dashboards are fast and every report agrees.
A safe API in front of an old database or application so new work can move forward.
Implementation approach
Contracts first, so the front end, the partner and the integration can proceed in parallel.
Current systems, records, volumes and rules mapped — including the ones only people know.
Data model and API contract agreed and documented before implementation begins.
Implementation with automated tests on the rules that matter, plus integration testing against real systems.
Environments, backups, logging and alerting set up so failures are visible before users report them.
Business benefits
Records live in one authoritative place; other systems read rather than duplicate.
The same calculation runs whether the request comes from a screen, an API or a job.
Logging and alerts mean a broken integration is noticed in minutes, not at month end.
Indexing, queues and caching designed for the volume you expect next year.
Least-privilege access, encrypted transport, audit trails and secrets kept out of the code.
A documented API lets you add a web app, mobile app or portal without rebuilding the core.
Who it's for
Several platforms in place, all correct on their own, none agreeing with each other.
An app or site that works until the data volume, rules or permissions become real.
Organisations that need a controlled, documented API instead of emailed exports.
Systems that were fine at launch and now slow down every reporting cycle.
Send us the systems involved and what has to stay in sync. We'll come back with an approach and the boundaries of a first phase.
