🎖️ Top Rated Plus | 10+ Years Experience
I help businesses turn data into automated decision-making systems using AI, LLMs, and full-stack engineering.
Most companies invest in AI but fail to operationalize it. I bridge that gap by building production-ready AI systems that integrate directly into your products, workflows, and infrastructure.
I’m Mehar, an AI/ML Engineer with 10+ years of experience delivering intelligent systems across healthcare, robotics, smart buildings, and semiconductor industries.
My focus is not just models it’s end-to-end AI integration:
From raw data → model → deployment → real business impact
Systems that automate workflows, reduce manual effort, and scale operations
I combine Claude (deep reasoning) + GPT-4o (speed & execution) with robust backend and MERN stack systems to build next-generation AI-powered applications.

LLM Chatbots (Claude + GPT-4o, context-aware, production-ready)
RAG Pipelines (enterprise knowledge systems)
AI Agents (autonomous, multi-step decision systems)
AI Integration into Web & SaaS Apps (MERN / APIs)
Computer Vision Systems (detection, segmentation, anomaly detection)
NLP Systems (classification, summarization, semantic search)
End-to-End AI Systems (data → inference → deployment)
