FOR SYSTEMS THAT SCALE WITH YOU

Backend & API Development

We build solid backends and APIs that run reliably, scale with demand, and integrate cleanly with your existing systems.

Systems that run under load

Some teams hand us a greenfield backend; others need one tricky integration solved or a second opinion on what they already run. We scope our involvement to match, and back every recommendation with something you can actually build on.

  • API Design & Development

    We design and build APIs that are clearly structured, well documented, and easy to evolve, a dependable interface for your own applications and external partners alike. Typical outputs: API concept and specification (e.g. OpenAPI); production-ready REST or GraphQL APIs; versioning, documentation, and conventions; developer-friendly onboarding for API consumers.

  • Custom Backend Development

    We turn your business logic into dependable, maintainable services, from data modelling to production-grade applications, test-driven from day one. Typical outputs: production-ready backend services; well-structured data models and database design; automated test coverage; clean, documented code your own team can own.

  • System Integration

    We make your applications and services work together reliably, whether ERP, CRM, payment providers, or legacy software, with consistent, traceable data moving between them. Typical outputs: integration concept and interface design; connections to third-party and in-house systems; reliable data synchronisation and messaging; monitoring and error handling for data flows.

  • Modernisation & Legacy Replacement

    We renew backends that have grown unwieldy over the years, phasing out legacy components without a risky big-bang switch, so the business keeps running throughout. Typical outputs: modernisation assessment and migration roadmap; incremental component replacement; data migration with no loss or downtime; a durable foundation your team can keep building on.

  • Performance & Scalability

    We hunt down bottlenecks and tune your backend for growing user numbers and data volumes, so your product stays fast and steady under load. Typical outputs: performance analysis and load testing; database and query optimisation; caching and asynchronous processing; an architecture that scales with demand.

  • Security & Reliability

    We build security and quality in from the outset, from authentication and access control to the careful handling of sensitive data, backed by thorough automated testing. Typical outputs: authentication and authorisation (e.g. OAuth2, SSO); secure handling of sensitive data; an automated test and CI/CD pipeline; monitoring, logging, and alerting.

What our clients say

Jim Kennedy
DRVN and OR have worked together since the earliest days of DRVN, and the relationship our teams built made the collaboration feel as if we were one company. OR's team was extremely knowledgeable and helped us deliver a very complex rewrite of a legacy connected vehicle system.

Start with a backend workshop

Working sessions that turn your requirements into a clear plan: a backend architecture, an API design, an integration map, or a modernisation path.

Backend Architecture & Feasibility Workshop

Backend Architecture & Feasibility Workshop

Target audience: Product Owners / CTOs / Developers Duration: Half day

Get a well-founded read on how your backend should be built. We weigh up requirements, architecture options, and integrations, and map out the most viable path to delivery.

System Integration & Data Flow Workshop

System Integration & Data Flow Workshop

Target audience: CTOs / IT Leads / Developers Duration: Half day

Get clarity on how your systems should work together. We map your landscape, pinpoint the integration points, and design reliable data flows between your applications and third-party services.

Legacy Assessment & Modernisation Workshop

Legacy Assessment & Modernisation Workshop

Target audience: Product Owners / IT Leads / Developers Duration: Half day

Take an honest look at a backend that has grown over time: what to keep, what to replace, and in which order. You leave with a dependency map and a modernisation sequence that avoids a big-bang cutover.

Frequently asked questions

The questions we hear most often about this service.

Can you build APIs and integrate with our existing systems?

Yes. We build solid backends and APIs and connect them to the systems you already run, from third-party services and payment providers to legacy platforms. Reliable integrations and clean, well-documented interfaces are core to what we do.

Can your backends handle scale and high load?

Yes. We design backends for the load they actually need to carry, with sensible data models, caching, and horizontal scaling, and we validate behaviour under realistic conditions rather than hoping it holds.

Do you document the APIs you build?

Always. Clean, well-documented interfaces are part of the deliverable, so your team and your partners can build against them without guesswork or reverse-engineering.
