I will build an ai saas, custom web app, or integration using nextjs and openai


About this gig
Building an AI SaaS, automated directory, or custom web app needing complex LLM integration? Plugging into OpenAI is easy; engineering a scalable, secure web app around it is hard.
Hi, I am Meer, a Full-Stack Developer specializing in Next.js and Node.js. I recently architected a scalable Next.js platform featuring a custom LLM backend pipeline that automatically crawls and generates structured content.
What I can build for you:
- AI-Powered SaaS MVPs from scratch
- Custom AI Web Applications & Dashboards
- AI Chatbots & Customer Support Agents
- Intelligent AI Websites & Directories
- Productionizing AI-generated MVPs (Lovable, Bolt.new, Cursor)
What I engineer for your app:
- Seamless Integrations: Secure connections with OpenAI, Claude, or custom APIs.
- Automated Workflows: Custom Node.js/Express pipelines to automate data processing.
- High-Performance UI: Blazing-fast React/Next.js frontends.
- Secure Infrastructure: Protected API routes, rate-limiting, and PostgreSQL/MongoDB schemas.
I don't build generic wrappers; I engineer scalable software. Message me your idea, and let's discuss the architecture!

FAQ
Do you use no-code tools like Bubble or WordPress for AI apps?
No. I engineer custom, full-stack web applications from scratch using Next.js, React, and Node.js. This ensures your AI SaaS is highly scalable, secure, and not limited by drag-and-drop constraints.
Can you integrate custom AI logic or just standard ChatGPT?
I can integrate standard LLM APIs (OpenAI, Claude) as well as architect custom backend pipelines to automate data processing, PDF generation, or specific content aggregation based on your database.
How do you handle database security and API keys?
Security is my priority. I utilize secure backend environments (Node.js/Express) to protect all LLM API keys and implement strict database schemas using PostgreSQL or MongoDB to ensure user data remains completely isolated and protected.
