Agentic E-commerce SaaS with LLM Chatbot, Voice, and Image Automation (MERN + n8n + Lovable)
Had a really positive experience working with him on this project. He handled the AI features, automations, and integrations reliably and with good attention to detail. Communication was smooth, updates were regular, and he was always open to suggestions. The work was delivered on time and worked as expected. Overall, a dependable developer and someone I’d be happy to work with again.

Multimodal OCR + Voice + LLM Summarizer for Medical Reports (MERN + n8n + LangChain)
Haider did an amazing job building our Healthcare SaaS AI platform. He integrated OCR, Whisper, and GPT-4V with LangChain to create clean, automated medical summaries. Very skilled with Node.js and n8n automation, great communicator, and fast turnaround. Super reliable and definitely someone I’d hire again for any AI or automation project.
