🎯 Visible Impact & Ambition

Every deploy reaches real guests this week. Lay rails for ML that can boost revenue 20%.

⏱️ Radical Autonomy

Plan sprints, own deploys; no committees.

• Direct line to decision-makers → zero red tape
• Modern DX: Next.js & React (latest stable), Tailwind, Prisma/Drizzle, Vercel, optional AI copilots – building mostly server-rendered, edge-ready flows.

📈 Success Milestones

• Week 1: First feature in production
• Month 1: Automation that saves ≥10 h/week for ops
• Month 3: Core platform stable; conversion up, load times down (aiming for <1s LCP); ready for future ML pricing (stretch goal: +20% revenue within 12 months).

🔑 What You’ll Own

1. Ship guest-facing features with Next.js (App Router / RSC / Server Actions).
2. Automate ops—dashboards & LLM helpers that delete busy-work.
3. Full lifecycle: idea → spec → code → deploy → measure → iterate.
4. Set up CI/CD & observability on Vercel; a dedicated half-day refactor slot each sprint keeps tech-debt low.
5. Optimise for outcomes—conversion, CWV, security, reliability; laying the groundwork for future capabilities in dynamic pricing and guest personalization.

Prototype > promise. Results > hours-in-chair.
