Project details
LLMs are powerful, but giving them direct access to your database often leads to hallucinations or dangerous queries. I will build you an autonomous, secure AI agent using the Model Context Protocol (MCP) to give your system strict, schema-validated access to your data.
This architecture is perfect for complex tasks like booking systems, inventory management, or customer service portals where accuracy is non-negotiable.
What I will deliver:
1. Zero-Hallucination Database Access: A standalone Node.js MCP server that exposes your database functions as secure, Zod-validated tools. The AI only executes exactly what it is allowed to.
2. Multi-Step Reasoning: The agent intelligently chains tools together (e.g., searching a user by name to find their ID before executing a cancellation protocol).
3. Generative UI: Instead of boring text responses, the AI streams interactive, custom React components (built on Next.js 15 App Router) directly into the chat interface (e.g., rendering a live booking confirmation card).
4. Sub-Second Orchestration: Powered by the Vercel AI SDK and Google Gemini, ensuring fast, stateful interactions.

Web-Based Calculation Model Development
Great experience working with Kethaka. He was easy to collaborate with, quickly understood the financial technicalities, and was very flexible throughout the project. Highly recommended.
About Kethaka
Full Stack AI Engineer | Autonomous Agents, Voice AI, RAG & SaaS
Kotugoda, Sri Lanka - 2:33 pm local time
If you are looking for a developer who can orchestrate advanced AI agents and build the scalable full-stack architecture to host them, you have found the right match. I combine robust software engineering with cutting-edge AI integration to deliver end-to-end SaaS solutions that actually do things—from executing live backend commands to securely querying private databases.
WHAT I CAN BUILD FOR YOU:
1. Autonomous AI Agents (MCP): I build agentic systems using the Model Context Protocol (MCP) to give LLMs secure, zero-hallucination access to local databases for real-time task execution. (Tech: Next.js, Node.js, Vercel AI SDK, Gemini)
2. Real-Time Voice AI: Engineered bidirectional VoiceOps assistants with sub-500ms latency, streaming raw audio over WebSockets to natively execute live server actions and backend commands. (Tech: WebSockets, Native Tool Calling, FastAPI)
3. Agentic GraphRAG & RAG Systems: Created advanced reasoning engines that use Graph Theory (Neo4j) to traverse unstructured data, alongside high-performance vector retrieval for complex document analysis and interactive 3D data exploration. (Tech: LangGraph, Ollama, Neo4j, Three.js)
4. Stealth Data Scraping & Automation: Developed advanced extraction pipelines capable of bypassing Cloudflare Turnstile to harvest target data and pipe it directly into automated workflows and CRMs. (Tech: Python, Playwright, SeleniumBase, n8n)
WHY WORK WITH ME?
1. Hybrid Architecture: Your AI won't just live in a terminal script. I deploy robust, highly responsive frontends and reliable backend servers to support it.
2. System Safety: I implement strict constraints and schema validations so your AI executes safe, predictable actions without hallucinating destructive commands.
3. Clear Communication: I strip away the jargon. Whether we are discussing vector databases, multi-agent loops, or automated workflows, I explain complex concepts in plain English.

Delivery time starts when Kethaka receives requirements from you.
Kethaka works on your project following the steps below.
Revisions may occur after the delivery date.
Schema Definition & Security Protocol
We map out your database schema and define strict, Zod-validated rules for what the AI can and cannot do.
MCP Server Construction
build the standalone Node.js MCP server to act as the secure bridge between the AI and your database.
