Level 2
About this gig
Need an AI chatbot that actually knows your business? I build custom AI agents and RAG chatbots that answer from your documents, website, and database, using OpenAI, Claude, Gemini, LangChain and Pinecone, with secure production-ready deployment.
What I Deliver:
- OpenAI Agents SDK Workflows: Stateful multi-agent networks with autonomous tool-calling and workflow orchestration via OpenAI Agents SDK or LangGraph.
- Custom MCP Servers + OKF: Model Context Protocol servers connecting LLMs to databases/APIs, backed by Open Knowledge Format (OKF) context graphs.
- Advanced RAG Systems: Hybrid retrieval pipelines using pgvector/Pinecone with reranking for precise, context-rich responses.
- AI Backend & Cloud: FastAPI micro-services with streaming, guardrails, and cloud deployment on AWS, GCP, Docker, or Kubernetes.
Why Choose Me? As a solutions architect, I deliver enterprise-grade security and modular code designed for production, not just quick demos.
If you are building an AI product, automation system, or AI SaaS, let's architect it properly from day one. Message me to get started!

FAQ
Which LLMs and frameworks do you support?
build across OpenAI (GPT-4o, Agents SDK), Anthropic Claude (Tool Use), Gemini, and open-weight models (Llama 3, DeepSeek), integrated via FastAPI, LangGraph, or custom Python/Node.js runtimes.
Can you deploy the AI infrastructure onto our existing cloud accounts?
es. I deliver production-ready Docker containers and deployment scripts for AWS, GCP, Azure, or private cloud environments, complete with environment variable security and CI/CD setup.
How do custom MCP Servers and OKF work together?
MCP provides the secure protocol for LLMs to execute tools and read external data sources. OKF organizes your system's metadata and business logic into a structured context graph. Together, they allow AI agents to navigate your database and APIs deterministically without hallucination.
What exactly is the Open Knowledge Format (OKF)?
OKF is a modern architectural approach that structures your application’s documentation, data models, and logic into a traversable graph of Markdown and YAML. It acts as a bridge, allowing AI agents and LLMs to seamlessly "read" and interact with your software without relying purely on basic vector
Can you handle compliance-heavy projects like healthcare apps?
Yes. I have extensive experience engineering secure Electronic Medical Record (EMR) systems, ensuring full HIPAA and GDPR compliance, and implementing SMART on FHIR and HL7 interoperability APIs.
