The brief
Design and roll out a web and mobile monorepo architecture, where the mobile app lived outside the existing monorepo and forced a package release for every shared change.

What I delivered
- Full monorepo architecture with Turborepo and pnpm workspaces, finally bringing the mobile app alongside the web app and shared modules.
- Removed the package release cycle that was blocking day-to-day mobile development.
- Designed a release process with the team, tailored to the monorepo and built to stay simple to operate.
- Shared design system across web and mobile through React Native Web, pooling components, business logic, types and tooling.
- Next.js web app with unified cross-platform navigation via Solito.
- Supported the team's move to agentic tooling: structuring the AGENTS.md files, splitting work across sub-agents, defining the rules and picking the right skills.
