Case Studies

Signals founder teams can reuse.

Three snapshots you can reuse or adapt: backend-driven mobile, design systems at scale, and AI in finance—each oriented to founder speed, quality, and leadership.

Backend Driven Development

Mobile UI from server “molecules”

Problem: Keeping iOS/Android UX in sync while shipping weekly.
Solution: Backend-defined “molecules” feeding SwiftUI and Compose with native renderers.
Impact: Parity in days, backend-led iteration, cleaner mobile code.

Why backend-driven? Weekly releases were blocked by rebuilding screens twice. By shipping “molecules” (backend-defined atoms + layout hints), both apps render native UI from a single contract—so parity comes from the backend, not parallel frontends.

Architecture. TypeScript backend emits JSON schemas describing molecules, layout, and data bindings. SwiftUI and Jetpack Compose clients have lean renderers that map schema → native views. Feature flags, A/Bs, and content edits flow from backend without app releases.

Delivery flow. Design shapes molecules → backend assembles layouts → apps render immediately. QA is schema-driven with contract tests; rollout is phased via backend targeting.

Results. iOS/Android parity within days, mobile code shrunk ~30%, and new flows launch from backend pushes. Ops leans on telemetry to retire or refactor molecules safely.

Design Systems (TBC)

Building durable design systems

Problem: Scaling UI across squads without divergence.
Solution: Token-driven theming, audited components, mobile + web governance.
Impact: In-flight — publishing soon.

AI in Finance (TBC)

Using AI for explainable finance

Problem: Delivering AI insights that regulators and clients can trust.
Solution: Explainability-first ML pipelines with human-in-loop review.
Impact: In-flight — publishing soon.
