/servicesWhat we build

IT services with defined deliverables

Four service lines. Each one lists what you receive, how long comparable work takes, and how the engagement is contracted — because a service description that cannot be checked is not a service description.

01 / Custom software development

Custom Enterprise Software Engineering

We design and build business software that has to keep working after we leave: domain modelling, a documented architecture, automated tests, and a deployment pipeline your own engineers can operate.

Typical duration: 8–30 engineering weeks depending on scope
Engagement: Fixed-scope project or dedicated team

Full service page

Included

Domain modelling and architecture decision records
React and TypeScript front ends; PHP 8.3, Node.js and Go services
Relational data modelling on MySQL and PostgreSQL
Automated test suites and continuous integration from the first sprint
Written handover: runbooks, environment setup, architecture notes

You receive

Working software in your own repositories and cloud accounts
Architecture documentation and decision log
CI/CD pipeline with reproducible builds

02 / Cloud infrastructure consulting

Infrastructure & Cloud Modernisation

Moving a system to the cloud is an architecture exercise, not a copy. We containerise workloads, define infrastructure as code, build the deployment pipeline, and put monitoring in place before the switchover — not after it.

Typical duration: 6–20 engineering weeks
Engagement: Project or shared-operation retainer

Full service page

Included

Containerisation with Docker and orchestrated deployment
Infrastructure as code with Terraform
AWS and Azure landing zones, networking and access boundaries
CI/CD pipelines in GitHub Actions or GitLab CI
Logging, metrics, alerting and an agreed response procedure

You receive

Infrastructure defined in version-controlled code
Deployment pipeline with rollback
Monitoring dashboards and alert routing

03 / Systems integration

API Systems & Integration Services

Integration work fails on the edges: retries, idempotency, partial failure and versioning. We design the contract first, publish it, and build services that behave predictably when a counterpart does not.

Typical duration: 4–16 engineering weeks
Engagement: Fixed-scope project

Full service page

Included

REST and gRPC service design with published contracts
OpenAPI specifications and generated client stubs
Message queues and event-driven integration patterns
ERP, CRM, payment and logistics connectors
Idempotency, retry and backoff strategies designed in, not retrofitted

You receive

Versioned API contract and reference documentation
Integration services with contract tests
Operational runbook for each connected system

04 / IT consulting and code audit

IT Advisory & Security Code Audits

A written, evidenced assessment of a system you already own — what it does well, where it will break, and what to do first. Findings are ranked by consequence and effort, with the reasoning attached so your team can disagree with us.

Typical duration: 2–6 engineering weeks
Engagement: Fixed-scope audit or advisory retainer

Full service page

Included

Static and manual review against the OWASP ASVS checklist
Dependency and supply-chain review
Architecture and scalability assessment
Delivery-process review: branching, testing, release practice
Prioritised remediation plan with effort estimates

You receive

Written audit report with evidence for every finding
Ranked remediation backlog
Walkthrough session with your engineering team

Not sure which of these you need?

Most enquiries start as one service and turn out to be another. Run your system through the scope matrix, or write to info@25dbr.com and describe the problem in your own words.
