Client had raised Series A and needed to hire engineers fast, but their codebase had no component library—every page was custom styled. New engineers took 3 weeks to ship their first feature.

Ship 40-component design system in 2 weeks reducing onboarding 3wks→4days

Audited existing UI patterns in Figma, consolidated into a design system with 40 components. Used Cursor to generate React components with Tailwind CSS, Storybook documentation, and unit tests. Integrated with their existing Next.js app.

New engineer onboarding time-to-first-feature dropped from 3 weeks to 4 days. Design-to-code handoff time decreased by 70%.

Client was pivoting from B2C to B2B but had no understanding of the new target persona. Traditional research agency quoted 6 weeks and $25K.

Complete 30-user research in 5 days vs 6-week agency timeline

Recruited 30 participants through LinkedIn outreach (Claude-drafted messages). Ran 20-minute remote interviews with a Claude-generated discussion guide. Used Claude to transcribe, tag, and synthesize findings into a persona document, jobs-to-be-done framework, and prioritized feature recommendations.

Delivered the full research report in 5 days at a fraction of the agency cost. Three of the four recommended features became the B2B product's core differentiation.

Client's operations team was managing customer accounts through a combination of Airtable, Slack commands, and direct database queries. Manual processes led to frequent errors and 15+ hours/week of admin overhead.

Build admin dashboard saving ops team 15 hours/week with <1% errors

Designed and built a custom admin dashboard in Next.js using Cursor. Claude generated the data models and API routes. Figma for the UI. Connected to their existing Postgres database with role-based access controls.

Ops team recovered 15 hours/week and error rate on account changes dropped from 8% to under 1%. The dashboard became their most-used internal tool.
