Hours worked: 6
What I did: Initial project setup. Scaffolded Next.js with Tailwind CSS 4. Defined the core AuditResult types and pricing-data.ts.
What I learned: Tailwind 4 configuration is much simpler but requires modern PostCSS setups.
Blockers: Deciding on the most accurate way to model "Seats" vs "Spend" for enterprise tiers.
Plan for tomorrow: Build the Audit Engine logic.
Hours worked: 8
What I did: Implemented the auditEngine.ts. Built out rules for team downgrades, API consolidation, and use-case-specific tool switching.
What I learned: Deterministic logic is easier to test and more reliable for financial recommendations than pure LLM prompting.
Blockers: Handling the "Research" consolidation rule correctly across multiple tools.
Plan for tomorrow: Build the Spend Form and Audit Results UI.
Hours worked: 7
What I did: Created SpendForm with React Hook Form and Zod. Built the AuditResults dashboard with the "Savings Hero" component.
What I learned: Client-side local storage is great for UX (preserving form state) but needs careful validation on reload.
Blockers: UI layout for comparing "Current" vs "Recommended" plans on mobile.
Plan for tomorrow: Integrate Gemini for AI summaries.
Hours worked: 5
What I did: Integrated @google/generative-ai. Implemented the /api/summary route with fallback logic.
What I learned: gemini-1.5-flash is significantly faster than pro for this use case.
Blockers: Gemini 404 errors during initial testing (fixed by switching model versions).
Plan for tomorrow: Deployment and Lead Capture.
Hours worked: 9 What I did: Replaced Prisma/SQLite with a Stateless Base64 Architecture to fix deployment issues on Vercel. Integrated Resend for email delivery. Finalized all documentation. What I learned: Encoding state in the URL is a powerful way to build "Serverless" shareable tools without DB overhead. Blockers: Resend "onboarding" email restrictions (added better user feedback). Plan for tomorrow: Final QA and launch.
