Company

Senior engineering capacity, without the agency overhead.

Onyx Digital Services provides experienced backend, cloud and architecture engineers to companies that need reliable execution and modern systems, and that cannot compromise on security or maintainability.

We work with a small number of clients at a time, most of them in financial services, trading technology and other sectors where systems are subject to regulatory scrutiny. Our engineers are used to working inside compliance frameworks: access control, change management, logging and documentation are part of how we build, not an afterthought.

We are a Gibraltar company, and we bring the jurisdiction's familiarity with financial services and online businesses to the technology we deliver.

Services

What we deliver.

Three disciplines, staffed by senior engineers, delivered either as scoped projects or as dedicated engineers embedded in your team.

Monitoring, alerting and incident response

Architecture and Advisory

Roadmap and platform strategy

Method

How an engagement runs.

Discovery

We clarify scope, success measures, constraints and the compliance context before a line of code is written.

Team

We propose engineers with directly relevant experience. You meet them before they start. Engagements typically begin within two weeks.

Build

Sprint-based delivery with code review, automated testing, weekly written reporting and a working demonstration at the end of each sprint.

Operate

Handover with documentation and runbooks, or continued support with monitoring, iteration and on-call cover by agreement.

Standards

What every client can expect.

Reporting: A written status report every week: what was delivered, what is next, what is blocked.
Quality: Automated tests, peer review on every change, and documentation kept current with the code.
Security: Least-privilege access, secrets management, dependency scanning and an audit trail of changes.
Confidentiality: Non-disclosure agreements as standard; client code and data stay in the client's own environments.
Ownership: All work product is assigned to the client on payment. No lock-in, no proprietary frameworks.
Collaboration: Engineers work in your tools, your repositories and your channels, with minimal friction for your team.
