Five services, one accountable partner
Custom software, SaaS products, the infrastructure they run on, and the senior judgement to decide what to build. Each ends with something you can point to: a release, a running platform, a written plan.
Custom Software
Business applications designed around how your organisation actually works, taken from idea to production and kept moving afterwards.
- APIs and integrations on Spring Boot
- React front-ends on one typed contract
- PostgreSQL models built for your real queries
SaaS Development
Multi-tenant cloud products built to be sold, scaled and operated, whether you are launching a first version or hardening one that already has customers.
- Tenant isolation, authentication and roles designed first
- Subscriptions and billing wired into the product
- Weekly releases as routine, not an event
DevOps as a Service
Experus builds, automates and watches the infrastructure behind your software, so your cloud stops being a distraction from your business.
- Infrastructure as code, in your accounts
- CI/CD with zero-downtime deploys and rollback
- Monitoring, backups and patches that are tested
Architecture & Technical Consulting
A senior second opinion before an expensive decision, or a clear diagnosis when a system is already hurting.
- Architecture reviews ranked by risk and effort
- Code, database and infrastructure audits
- Technology selection backed by a proof of concept
Legacy Modernisation
Bring an ageing Java system up to date without a big-bang rewrite, while it keeps serving the business that runs on it.
- Spring Boot upgrades one module at a time
- Safety-net tests around existing behaviour first
- Database clean-up with rehearsed, reversible cut-overs
Which service is the right starting point?
| Question | Custom Software | SaaS Development | DevOps as a Service | Architecture & Technical Consulting | Legacy Modernisation |
|---|---|---|---|---|---|
| Best when | A process runs on spreadsheets, email or a tool nobody can change. | You are selling software to many customers, or about to. | Deployments are manual, monitoring is thin, one person knows how. | An expensive decision is coming, or a system is already hurting. | An ageing Java system still runs the business daily. |
| You get | A working application in production, with tests and documentation. | A multi-tenant product your customers pay for and rely on. | Reproducible infrastructure, automated releases, monitoring that reaches Experus (and you) before your users do. | A written report, ranked by risk, and a clear recommendation. | Current versions, safety-net tests and a phased roadmap. |
| Typical shape | Scoped first release in increments, then a retained agreement. | Build and launch, then retained product-engineering partnership. | Fixed-scope set-up or audit, then monthly managed operations. | Short fixed-price review, or a standing advisory day each month. | Assessment and roadmap, then staged delivery you can pause between. |
| Starts with | A conversation about the process, then a written scope. | A conversation about who pays and for what, then tenant, auth and billing design. | A look at your current environment and how releases happen today. | The decision or symptom you need a straight answer on. | An assessment that maps risks before anything is changed. |

Not sure which fits? Describe the problem instead
You do not need to pick a service before getting in touch. Describe the system, the idea or what is hurting, and Experus will tell you which of these applies, or whether something simpler would do. A considered reply from the engineer who would do the work, with no obligation.
