What we do

01

AI-accelerated software delivery

We use AI agents to make software delivery simpler, faster and more predictable, and we can set up the same approach for your teams. Applied at Turner & Townsend and On.

  • A standardised, agentic workflow that takes each ticket from analysis and planning through implementation, testing and code review
  • Works inside your existing process and tools: tickets and team updates stay in step, and review feedback is picked up and resolved in the same loop
  • Every change follows the same steps and quality gates, so delivery becomes predictable
  • New features ship faster and with fewer defects, and bugs are fixed sooner

02

AI solutions & agentic systems

We design and build AI that works with your own data and runs reliably in production, not just in demos.

  • Assistants and agents that answer questions from company knowledge, analyse documents and recordings, and help troubleshoot issues
  • Human approval built in for sensitive actions
  • Provider-neutral design: changing AI provider is a configuration change, not a rewrite
  • Secured with your company sign-on and monitored for quality and cost

Cloud-native engineering & modernisation

  • Scalable, event-driven and serverless systems on AWS, Microsoft Azure and Google Cloud

Why EXTUNI

Senior, accountable, accelerated by AI

  • AI-accelerated, quality built in

    AI agents work inside a standardised workflow with automated tests and code review, so features ship faster and more predictably, with fewer defects.

  • Senior from day one

    No ramp-up and no hand-off to junior staff: the person who designs the solution builds it.

  • Platforms, not just projects

    We build reusable foundations (service templates, shared frameworks, automated pipelines) so teams keep delivering faster after we leave.

  • Vendor-neutral

    Hands-on across AWS, Azure and Google Cloud, and across AI providers. We recommend what fits.

  • Transparent and lean

    Clear scope, regular demos and direct access to the engineer doing the work.
