Project details
You will get a custom AI chatbot or RAG system integrated directly into your existing web app. With 12+ years of full-stack development experience — including building AI-powered features for enterprise platforms serving 6M+ users — I connect LLMs like OpenAI, Claude, or open-source models to your product without disrupting what's already working.
I've built RAG systems with citation-grounded retrieval and agentic customer support tools using LangChain.js and vector search. Whether you need a simple support chatbot or a full document-Q&A system, I scope the right approach for your actual use case rather than over-engineering it.
You'll get clean, documented code your team can maintain, clear communication throughout, and a working AI feature tailored to your data and users — not a generic bolt-on.

Job Success
Lahore, Pakistan - 1:25 pm local time
Over 12+ years I've shipped platforms across real estate, edtech, fintech, and SaaS — including a live video communication module handling real-time sessions (Vonage APIs + GraphQL + Hasura) and a vehicle inspection and auction platform for enterprise B2B clients at Petromin. I've also built AI-powered chatbots, automation, and generative features into products already in production. Combined, these platforms have served 6M+ users and 10,000+ active business licenses.
I work closely with clients through the full cycle — requirements, architecture, delivery, and iteration. Clients consistently describe me as collaborative, reliable, and solution-oriented, and clear communication through the project is non-negotiable for me.
If you need a senior developer who can own a feature end-to-end, integrate AI into your existing stack, or help scale a product that's already live — send me an invite. I'd love to hear what you're building.
Steps for completing your project
After purchasing the project, send requirements so Syed can start the project.
Delivery time starts when Syed receives requirements from you.
Syed works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery and scope review
I review your codebase, data sources, and use case to confirm the right approach — simple chatbot vs. full RAG pipeline — and flag any technical considerations before starting.
Set up vector search and data pipeline
I process your documents or data into a vector database and set up retrieval logic so the AI can pull accurate, relevant context for each question.
