Production AI Systems That Actually Work
I build LLM applications, RAG systems, autonomous agents, and voice AI — engineered with guardrails, structured outputs, and deterministic state machines.

How I architect ai systems
Data Ingestion
Parse documents (PDF, HTML, audio) into structured chunks with metadata preservation and semantic boundaries.
Embedding & Indexing
Generate dense vector embeddings via OpenAI/Cohere, store in pgvector with HNSW indexing for sub-100ms retrieval.
Hybrid Retrieval
Combine dense semantic search with BM25 keyword matching, apply reciprocal rank fusion and cross-encoder reranking.
LLM Reasoning
Route through Claude/GPT with deterministic prompt templates, structured JSON output, and citation enforcement.
Guardrails & Output
Validate via Pydantic/Zod schemas, apply hallucination prevention, and stream results with source attribution.
Featured Work
Production projects as a AI engineer
Kookabe AI Suite
Enterprise WhatsApp RAG Chatbot & Automated AI Voice Mail
Problem
Companies received hundreds of repetitive WhatsApp voice notes, PDFs, and product inquiries daily, resulting in 4-8 hour response delays and missed sales leads.
Solution
Built a hybrid RAG system with pgvector and Claude 3.7 that parses customer inquiries, searches internal PDF documentation, and generates accurate answers with human-handoff triggers.
Architecture
- WhatsApp Business API webhooks ingesting incoming text, voice notes, and document files
- Hybrid RAG combining pgvector dense embeddings with BM25 keyword reranking
- FastAPI backend handling asynchronous LLM streaming and conversation state
- Automated audio transcription pipeline extracting lead data directly into CRM webhooks

Process
How I work
Understand the Domain
Map your data sources, user queries, and accuracy requirements before writing a single line of code.
Architecture Design
Design the retrieval pipeline, model selection, embedding strategy, and guardrail layers.
Iterative Development
Build in sprints with measurable retrieval accuracy metrics, not just vibes.
Production Hardening
Add caching, rate limiting, fallback models, monitoring, and cost governance before shipping.
FAQ
Frequently asked questions
What makes your RAG systems different from basic implementations?
I build hybrid RAG with dense embeddings + BM25 sparse search, reciprocal rank fusion, and cross-encoder reranking. Every answer includes strict source citations and hallucination prevention guardrails — not just naive vector similarity.
Do you build multi-agent systems?
Yes. I use LangGraph for cyclical state machine architectures with persistent checkpointing, dead-loop prevention, and explicit human-in-the-loop approval gates for critical operations.
Can you integrate AI into an existing product?
Absolutely. I specialize in embedding AI capabilities into production SaaS — streaming completions, token-budgeted prompt caching, semantic caching with Redis, and graceful degradation when model providers experience latency.
What about voice AI and audio processing?
I build voice qualification pipelines — WhatsApp audio transcription via Whisper, intent extraction into structured CRM data, and natural voice synthesis responses with ElevenLabs.
Need a production AI system built?
From hybrid RAG to autonomous agents — I engineer AI that works in production, not just in demos.
