Jay G.

I build AI agents and full-stack SaaS products using Python, FastAPI, React, Next.js, LangGraph, LangChain, and leading AI models.

I am a Top Rated Plus engineer with 100% Job Success, $100K+ earned, and 5,900+ hours delivered on Upwork. I have worked on AI agents, healthcare platforms, customer support automation, RAG applications, AI chatbots, document intelligence, and workflow-heavy SaaS products.

My role is not limited to prompts or model integration. I work across the complete product layer, including agent workflows, backend APIs, frontend applications, databases, authentication, integrations, permissions, and cloud deployment.

Before recommending an AI solution, I first understand the users, existing workflow, available data, integrations, security needs, and the business result the system should achieve. This helps determine whether the right solution is an AI agent, multi-agent workflow, RAG system, internal assistant, conventional automation, or a simpler software feature.

What I can help you build:

• AI agents connected with APIs, databases, CRMs, support platforms, and internal tools
• Single-agent and multi-agent workflows using LangGraph and LangChain
• Full-stack AI SaaS products using Python, FastAPI, React, and Next.js
• Customer support agents, AI copilots, onboarding assistants, and internal business tools
• RAG applications, document Q&A, semantic search, and knowledge assistants
• Secure backend APIs, authentication, role-based access, and admin dashboards
• Healthcare AI platforms, clinical workflow tools, and HIPAA-aware applications
• AI integrations using OpenAI, Azure OpenAI, Claude, Gemini, and other models
• Existing AI prototypes that need better architecture, accuracy, integrations, or production readiness

My core technology stack includes:
Python, FastAPI, Django, React, Next.js, TypeScript, JavaScript, LangGraph, LangChain, OpenAI, Azure OpenAI, Claude, Gemini, PostgreSQL, MongoDB, Redis, Pinecone, Qdrant, pgvector, REST APIs, GraphQL, AWS, Azure, GCP, Docker, and CI/CD.

I have worked across healthcare, customer support, fintech, real estate, data analytics, productivity, and enterprise workflow products. My focus is always on building systems that are practical, secure, scalable, and useful in real business operations.

I am a good fit when you need someone who can take ownership of the complete AI product, from understanding the workflow and planning the architecture to building the backend, frontend, agent logic, integrations, and deployment.
