Engineering Overview & Execution Strategy
Transform unstructured business documents, customer inquiries, and knowledge bases into intelligent, conversational AI tools. I integrate OpenAI, Anthropic Claude, and open-source LLM models using vector databases like pgvector and Pinecone with strict prompt guardrails and sub-second streaming answers.
Key Architectural Pillars
Retrieval-Augmented Generation (RAG)
Connecting large language models to your custom business knowledge base with hybrid semantic and keyword search.
Vector Embeddings & Semantic Indexing
High-dimensional vector storage with pgvector / Pinecone for lightning-fast similarity matching and knowledge retrieval.
Streaming Conversational Interfaces
Real-time SSE token streaming UI with message history memory, markdown rendering, and exportable chat sessions.
Prompt Guardrails & Rate-Limiting
Defensive prompt engineering preventing prompt injections, hallucination controls, and token usage budget throttles.

How I Work: From Requirements to Deployment
My project process covers discovery, design, development, testing, deployment, and ongoing support. We agree on the scope and milestones before implementation so you know what is being built and how progress will be reviewed.
Discovery, Requirements & System Architecture
We analyze business requirements and engineer robust relational database schemas (PostgreSQL), high-throughput API contracts, and scalable cloud topology before writing a single line of code.
