AI-native engineering

Our AI-Native Engineering Standards

AI-native by practice, engineer-led by principle. We use AI-assisted tools at every step of design, development, launch and growth, and a senior engineer still owns every architecture decision, every security review and every line that reaches production.

01Design
- AI-Assisted Discovery and Prototyping
  We use AI to map requirements, user stories and workflows, and to turn them into a clickable prototype your stakeholders can test before production code is written.
  Engineer-ledOur team runs discovery with you and agrees the scope before anything is built.
- Pixel-Perfect UI/UX and Design Systems
  AI speeds up layout variations, accessibility checks and design-to-code handoff, on a shared design system in Figma.
  Engineer-ledDesigners make every design decision, and every screen is built to match the approved design on every device.
- Architecture-First Planning
  We settle the architecture, data model, state management and integrations before the build starts, so the product scales without a rewrite.
  Engineer-ledA senior engineer owns every architecture decision.
02Build
- AI-Assisted Development, Human-Owned Code
  Our developers use Claude Code, GitHub Copilot and Cursor for scaffolding, boilerplate and repetitive patterns.
  Engineer-ledSenior engineers own the logic, and a developer reviews every AI-generated change.
- Coding Standards, Git Flow and Peer Review
  Code follows agreed standards and a Git Flow branching model, and AI-powered review flags issues on every commit.
  Engineer-ledA second developer reviews every change before it merges.
- Secure and Compliant by Default
  We work under ISO 27001 and ISO 9001 certified processes, build to SOC 2-aligned controls, and add HIPAA-aligned safeguards where health data is involved.
  Engineer-ledA senior engineer owns every security review. Independent security agencies run penetration tests, and we remediate their findings.
03Ship
- AI-Generated Tests and Manual QA
  AI generates unit tests, edge cases and regression suites from the codebase.
  Engineer-ledQA engineers test the real user flows by hand before every release.
- Static Analysis and CI/CD Pipelines
  Static code analysis scans every commit, and CI/CD pipelines build, test and deploy across development, staging and production.
  Engineer-ledEngineers set the quality gates the pipeline enforces and fix what the scans flag.
- Phased, Monitored Releases
  Alpha and beta builds go to internal and external users first, and releases roll out in phases with a rollback plan.
  Engineer-ledYou get a demo build after every sprint and review it with the team.
04Grow
- Monitoring, Analytics and Performance
  Crash reporting, performance monitoring and usage analytics are in place from launch day, and for mobile apps we track Google Play and App Store analytics too.
  Engineer-ledOur engineers keep checking crash reports and store analytics for the life of the product, so it stays stable long after launch.
- Data-Driven Iteration and Growth
  We plan in two-week sprints and prioritise new features from user feedback and analytics, not guesswork. For clients without an in-house marketing team, we also run the product growth strategy after launch.
  Engineer-ledDaily stand-ups and sprint demos keep you in every decision about what ships next.
- Documentation, Ownership and Ongoing Support
  AI keeps API references and technical docs in sync with the code, and maintenance plans keep the product secure and up to date.
  Engineer-ledYou get full repository access and IP ownership, and one in-house senior team stays accountable for the outcome.

Scale Without the Headaches

Get a backend built for high traffic, real-time data, and easy maintenance - without overpaying or overengineering.
