AI-native engineering
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
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.
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.
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
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.
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.
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 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 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.
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
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.
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.
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.
