You will get a production AI agent: LangChain, RAG + Next.js, deployed to Vercel
Top Rated
Project details
Most "AI agent" catalog items deliver a Python script or a LangChain backend with no interface. You get code. You still need a developer to wire it into something usable.
This project delivers the agent and the product around it. A working Next.js interface your users can actually open, connected to an AI agent that observes, reasons, and takes action on a defined task. Production-ready from day one.
What I build agents for: lead qualification and outreach, document review and extraction, knowledge base search and summarisation, content scoring and classification, meeting transcription and coaching, workflow automation with API tool calls.
Stack: Next.js, TypeScript, Node.js, OpenAI or Anthropic Claude, LangChain orchestration, Pinecone where retrieval is needed, deployed to AWS. Rate limiting, error handling, and cost controls included, not added later.
Best fit: founders who want a specific business task automated with AI, SaaS teams adding an autonomous feature, and CTOs who need a proof-of-concept that looks like a real product.
Not a fit: vague "build me an AI agent" requests without a defined task or outcome.

Great communication. Good team player. With Abdul's expertise, sometimes we would recommend features or changes that we had not thought of. Insightful.

Build SEO-Optimized Job Board with Next.js (Bullhorn API, JSON-LD Schema, Server-Side Rendering)
This is second project Abdul finished for us and he has already started third project for us. Needless to say we are quite satisfied with his work. Every time we release a new project, we have many developers apply for the project, we do conduct interviews for each project. Yet, we've gone back to Abdul for the third time. What's different about Abdul is his communication, despite our time zone difference and work our differences, he is always responsive and sets the expectation clear. He asks thoughtful questions. As he dives deeper into the project, he provides his insights and recommendations as well.

HOW I WORK
For an existing product, I first understand the architecture, business workflow and current risks before recommending changes.
For a new product, I help define the smallest serious production release, structure the database and integrations, divide delivery into clear milestones and provide working software throughout the engagement.
You receive:
• Proactive written updates
• Clear technical decisions and trade-offs
• Clean, maintainable code
• Testing for business-critical workflows
• Client-owned repositories and service accounts
• Deployment documentation and structured handover
My strongest engagements are production SaaS products, platform modernization, complex integrations and business workflows where reliability matters as much as development speed.
Send me a short description of your product, its current stage and the result you need. I will tell you the safest first step and whether I am the right person for it.
