Ceylon Labs AI

Software that carriesreal load.

AI is only as useful as the software around it. Our software engineers build the platforms, products and integrations that put intelligence into the hands of real users. Code-reviewed, tested and documented.

Discuss a software project

A production system, assembled.

Scroll to see how the layers of a system we deliver fit together, and which team owns each one. (The answer is the same team.)

  1. Cloud infrastructure

    Infrastructure as code on AWS, Azure or Google Cloud: reproducible, secured, in your account.

  2. Databases

    PostgreSQL, MongoDB and vector stores, modelled for the queries you will actually run.

  3. AI models

    LLMs, ML models and retrieval pipelines, versioned and evaluated against agreed thresholds.

  4. Backend services

    Domain services in Python, TypeScript, Java or Go: tested, observable, documented.

  5. APIs

    Versioned contracts for your apps, partners and agents, with authentication built in.

  6. Frontend

    Web interfaces and mobile apps people enjoy using, in the framework that fits.

  7. Monitoring

    Dashboards, alerting, model-drift and cost monitoring across the whole stack.

Software engineering services.

Built in the languages, frameworks and cloud your project needs, not the ones we happen to prefer.

  • Enterprise Software Development

    Business platforms engineered for scale, security and long service life.

  • Full-Stack Development

  • Legacy System Modernization

    Incremental modernization of the stack you have, keeping the business running throughout.

  • Cloud-Native Development

    Containerised, observable services on the cloud you choose, or your own servers.
