Full-stack web systems, from database to deployment
Some requirements outgrow a website: booking engines, partner portals, onboarding platforms, internal workflow tools. These need a real data model, a well-designed API, secure authentication and cloud infrastructure that can be operated by your team. Geosterling Systems designs and builds that whole stack as one coherent system.
The service suits operations leaders and CTOs replacing spreadsheets, email chains or ageing software with a purpose-built application. We consider data residency, audit trails and Arabic-English usability early, since they are much harder to add at the end.
What you get
A relational data model and migration scripts, designed around your business entities.
A documented API with authentication, authorisation and input validation.
A responsive web front end, bilingual with RTL where needed.
Cloud infrastructure defined as code, with environments, logging and backups.
Source code, technical documentation and post-launch support.
When you need this
- An operations team running a critical process across spreadsheets and email that needs a proper system of record.
- A partner, agent or supplier portal that has to expose selected data from internal systems securely.
- A workflow or approvals platform that needs roles, audit history and notifications.
- A product prototype that now needs production-grade engineering, authentication and hosting.
How we work
Requirements and data modelling
We work with the people who run the process to capture rules, exceptions and reporting needs, then model the data before building interfaces.
Architecture and security
Hosting region, authentication, permissions and integration points are decided early, with data residency considered where it applies.
Incremental delivery
The system is built and released in working increments, so your team can use and correct it before the full scope is finished.
Go-live and operations
We deploy, monitor, migrate existing data and hand over documentation, then support the system through the post-launch period.
Frequently asked questions
What affects the cost of a custom web system?
Mainly the number of user roles, the depth of business rules, integrations with existing systems and reporting needs. We scope these during discovery, and provide a quote rather than a generic figure.
Can you integrate with our ERP, CRM or existing APIs?
Yes. We connect to systems such as Salesforce, HubSpot, SAP and custom ERPs, or anything that exposes an API, and we design the integration so failures are visible and recoverable.
Who maintains the system after launch?
Post-launch support is included, and the source code and documentation are handed over, so your own engineers or another provider can take over. Some clients keep us on a retainer for continued development.
