Umar Asif
About this gig
Most companies are sitting on a goldmine of PDFs, docs, and notes that no one has time to read. I help you turn that static info into an Interactive AI Chatbot that actually talks to your customers and team in real-time.
Using Next.js AI and LangChain, I build custom solutions that don't just "chat" they actually understand your specific business rules and data.
What this does for you:
- 24/7 Expert Support: Your AI handles the repetitive questions via OpenAI API, freeing you up for high-value work.
- Hyper-Personalized: Answers are pulled directly from your knowledge base using a custom Vector Database (RAG).
- Built to Scale: Whether you have 10 users or 10,000, your AI Agent handles the load without you needing to hire more staff.
- Clean Tech Stack: You get a sleek, fast Next.js interface with code thats easy to maintain.
Your data shouldn't stay silent. Lets build a tool that works while you sleep.
Ready to start? Drop me a message and let's talk about your project!

Hi, I’m a software engineer focused on best implementations, scalable development, and clean system design. I started as a Full Stack Intern, grew into a Junior Engineer, and now contribute to open source at Palisdoes Org, working with DevContainers, Docker workflows, and API orchestration. I build end-to-end web and mobile solutions using MERN, Next.js, and React Native, and integrate AI systems like Groq/Llama for real-world use cases. I’ve automated production systems such as Australia’s E-challan flow. Let’s work together to scale and build better software.

FAQ
What is an "AI Agent with RAG" and how does it help my business?
Think of it as a custom AI assistant that has read all your company’s specific documents (PDFs, manuals, or database). "RAG" stands for Retrieval-Augmented Generation. It simply means the AI looks up your private data to give 100% accurate, personalized answers instead of making things up.
Do I need to provide my own OpenAI API key?
Yes, usually you will provide your own API key (from OpenAI, Anthropic, or Google) so you have full control over your costs and data. I will guide you through the 2-minute process of setting this up if you’ve never done it before!
Is my private business data secure?
Absolutely. Your data is stored in a secure "Vector Database" (like Pinecone or Supabase) that only your application can access. The AI only sees the data when it needs to answer a specific question, and your documents are never used to "train" public AI models.
Can I update the documents the AI "reads" later on?
Yes! In the Standard and Premium packages, I build an easy way for you to upload new documents or delete old ones so your AI stays up-to-date as your business grows.
Why use Next.js for this AI application?
Next.js is the gold standard for modern web apps. It makes your AI agent lightning-fast, SEO-friendly, and very easy to scale. It ensures your users have a smooth, professional experience without annoying lag.
Will the AI ever give wrong information (hallucinate)?
While no AI is perfect, using RAG significantly reduces "hallucinations." By forcing the AI to fetch facts from your documents first, it acts more like a librarian than a storyteller, ensuring much higher accuracy.
Do you provide the full source code?
Yes! Unlike "no-code" platforms that charge you monthly fees, I provide the full source code. You own the product entirely and can host it wherever you like.
