The original title is "Four lessons from building AI, education, and healthcare products with Next.js"

Short summary

A developer shares four product builds spanning generative AI (Klyro), job search (RoleMint), education (BrightLearn), and clinic CRM (FizioKinetoMaxim), all built with Next.js. Key lessons include credit reservation for AI billing, human checkpoints for AI-generated job materials, and role-based access for sensitive healthcare data. The post doubles as a portfolio showcase with links to live demos and the author's LinkedIn and support pages.

• •Credit reservation and settlement pattern for metered AI billing
• •Human-in-the-loop checkpoint for AI-generated professional materials
• •Role-based access and traceability for healthcare CRM operations
