Key takeaways include creating consistent experiences around AI services, implementing human checkpoints for AI-generated content, and designing robust data relationships.", "body_md": "Over the last few years, I have built products in very different domains: generative AI, job search, education, and clinic operations.\n\nAlthough the interfaces and users are different, several engineering lessons appeared repeatedly.\n\nKlyro brings together streamed chat, cited web search, image analysis, and image generation.\n\nThe difficult part was not simply connecting several AI services. It was creating one consistent experience around them: shared authentication, one responsive interface, predictable errors, subscriptions, billing, and a transparent credit balance.\n\nFor every operation, Klyro estimates the cost, reserves the required credits, and settles the balance according to actual usage. When an operation fails, the reserved credits are released.\n\nLive product:\n\n[https://www.klyroai.net](https://www.klyroai.net)\n\nRoleMint is a job-search copilot that discovers opportunities, compares them with a candidate’s profile, generates ATS-oriented materials, and organizes applications in a visual pipeline.\n\nThe user remains responsible for reviewing and approving every generated application. That human checkpoint is important when AI-generated content represents someone professionally.\n\nBrightLearn supports lessons, categories, tags, quizzes, questions, answers, attempts, scoring, and progress history.\n\nIt was built with Next.js, TypeScript, Prisma, PostgreSQL, Clerk, and AI integrations. Designing the relationships between learning content and user attempts was just as important as building the interface.\n\nBrightLearn is open source:\n\n[https://github.com/RobertIonutF/brightlearn](https://github.com/RobertIonutF/brightlearn)\n\nApplication:\n\n[https://medilearn-rose.vercel.app](https://medilearn-rose.vercel.app)\n\nFizioKinetoMaxim is a protected CRM for clinic operations. It centralizes patients, appointments, medical and administrative activity, CAS cases, exercise programs, feedback, reports, incidents, complaints, and audit history.\n\nThe application uses Next.js, TypeScript, and Convex for reactive data and real-time workflows. Role-based access and traceability were essential because the application handles sensitive operational processes.\n\n[https://fiziokineto-maxim-crm.vercel.app](https://fiziokineto-maxim-crm.vercel.app)\n\nI work on complete SaaS products, AI integrations, CRM systems, educational platforms, and operational dashboards.\n\nIf you need something similar, you can contact me through LinkedIn:\n\n[https://www.linkedin.com/in/robertionutfundulea/](https://www.linkedin.com/in/robertionutfundulea/)\n\nYou can also support my independent projects here:\n\n[https://buymeacoffee.com/robertfundulea](https://buymeacoffee.com/robertfundulea)", "url": "https://wpnews.pro/news/four-lessons-from-building-ai-education-and-healthcare-products-with-next-js", "canonical_source": "https://dev.to/robertionutfundulea/four-lessons-from-building-ai-education-and-healthcare-products-with-nextjs-3nm7", "published_at": "2026-07-27 19:20:30+00:00", "updated_at": "2026-07-27 19:31:45.861979+00:00", "lang": "en", "topics": ["artificial-intelligence", "generative-ai", "developer-tools", "ai-products"], "entities": ["Next.js", "Klyro", "RoleMint", "BrightLearn", "FizioKinetoMaxim", "Prisma", "PostgreSQL", "Clerk"], "alternates": {"html": "https://wpnews.pro/news/four-lessons-from-building-ai-education-and-healthcare-products-with-next-js", "markdown": "https://wpnews.pro/news/four-lessons-from-building-ai-education-and-healthcare-products-with-next-js.md", "text": "https://wpnews.pro/news/four-lessons-from-building-ai-education-and-healthcare-products-with-next-js.txt", "jsonld": "https://wpnews.pro/news/four-lessons-from-building-ai-education-and-healthcare-products-with-next-js.jsonld"}}
