AI LLM Developer for Healthcare E-Consent & Patient Chatbot Systems Aadhar developed a high-quality LLM-based chatbot. We had hardware constraints and needed a model able to run on a commodity GPU. Aadhar developed the software architecture, harness and GUI. We couldn't have gotten a better result. I would definitely hire Aadhar again; he delivers high-quality work.

Panchkula, India - 3:46 am local time
I am an experienced AI Developer and Full Stack Developer specializing in building production-ready AI applications, AI agents, AI SaaS platforms, Generative AI solutions, LLM applications, RAG systems, and AI automation workflows.

With 10+ years of software development and AI development experience and strong hands-on experience with Python, FastAPI, Node.js, javascript, React, Next.js, PostgreSQL, OpenAI, Claude, Gemini, LangChain, LangGraph, RAG, vector databases, and AI automation, I work across the complete AI application stack.

I specialize in AI-powered healthcare applications, clinical AI, healthcare automation, FHIR-based systems, healthcare data integration, RAG pipelines, and AI agents for HealthTech platforms.

I also work with Hermes Agent integrations, connecting AI agents with external APIs, tools, MCP servers, custom applications, and automated workflows.

What I build

• AI Agents and autonomous workflows
• AI Developer solutions using OpenAI, Claude, and Gemini
• LLM applications and AI assistants
• RAG systems and knowledge bases
• AI chatbots and conversational applications
• AI document processing and data extraction
• AI workflow automation
• Streamlit Dashboard
• Hermes Agent integrations,
• Multi-agent and tool-calling systems
• AI SaaS and multi-tenant platforms
• OpenAI, Claude, and Gemini integrations
• Custom AI API and third-party integrations
• Vector search using pgvector, Pinecone, and FAISS
• AI-powered dashboards and business applications
• n8n, API, webhook, and workflow automation
• Shopify and N8N automation

My AI Development Approach

I do not treat an LLM as just a chatbot.

For agent-based systems, I design the application around tools, structured inputs and outputs, retrieval, agent loops, validation, permissions, business rules, memory, and API execution.

For example, an AI agent can:

Understand → Retrieve context → Decide → Call tools → Validate → Execute → Record results → Continue the workflow

This makes the system much more reliable for production use cases such as AI automation, CRM workflows, marketing automation, document intelligence, recruitment, healthcare, SaaS, and business operations.

As a Python AI Developer, I commonly use Python, FastAPI, PostgreSQL, Supabase, Redis, pgvector, FAISS, and cloud infrastructure to build scalable AI backends. On the frontend, I work extensively with React, Next.js, TypeScript, Tailwind CSS, and modern SaaS architectures.

Technology Stack

AI / LLM: OpenAI, Anthropic Claude, Google Gemini, Hugging Face, GPT, LLM APIs
Agents: LangChain, LangGraph, tool calling, custom agent workflows
RAG: Embeddings, pgvector, Pinecone, FAISS, semantic search
Backend: Python, FastAPI, Django, Node.js, Express, NestJS
Frontend: React, Next.js, TypeScript, Tailwind CSS
Database: PostgreSQL, Supabase, MongoDB, Redis
Automation: n8n, APIs, webhooks, background jobs
Cloud: AWS, GCP, Azure, Vercel, Docker, CI/CD
Integrations: Google APIs, Google Ads, Meta Ads, Stripe, Shopify, CRM and SaaS APIs

As an AI Developer, I help startups and businesses turn AI ideas into production-ready applications, from AI MVPs and intelligent chatbots to complex RAG systems, AI agents, document intelligence platforms, and workflow automation.

If you need an AI Developer, AI Agent Developer, LLM Developer, RAG Developer, AI Automation Engineer, or Full Stack AI Developer who can take an AI concept through architecture, development, API integration, and production deployment, I can help.
