About Chibuzor

I help businesses automate workflows, enhance customer experience, and drive measurable results through intelligent, LLM-powered solutions. As an AI/ML Engineer and Full-Stack Generative AI Developer, I specialize in building scalable systems that combine automation, reasoning, and data-driven intelligence.

I develop Agentic AI systems, Retrieval-Augmented Generation (RAG) architectures, and Conversational AI platforms that transform complex data into actionable insights using Python, LangChain, OpenAI API, and modern vector databases.

What I Build:
• RAG & Knowledge Systems – Built retrieval-augmented pipelines with FAISS and pgvector to boost context relevance and answer accuracy.
• Conversational AI & Chatbots – Delivered production assistants that reduced support workload by 45% and increased engagement by 35%.
• Automation & Multi-Agent Workflows – Designed proposal generators, email agents, and workflow automations that cut manual effort by 80%.
• Cloud & MLOps Deployment – Deployed scalable AI solutions on AWS, GCP, and Docker with secure API endpoints for seamless integration.

Tech Stack:
Python • LangChain • OpenAI API • LangGraph • Autogen • FAISS • pgvector • FastAPI • Next.js • Streamlit • PostgreSQL • Docker • CI/CD • NLP • Prompt Engineering • Multi-Agent Systems

Client Impact:
• Zenovo AI (U.S.) – Built proposal automation reducing drafting time by 80%.
• Junify AI (Australia) – Delivered conversational intelligence improving workflow efficiency by 60%.
• EmailGen – Created a multi-agent email system that cut outreach time by 70% and boosted campaign engagement by 35%.

I’m passionate about building AI systems that think, learn, and deliver measurable business impact. If you want to integrate RAG, agents, or automation into your business, I’ll help you deploy fast, reliable, and revenue-driven AI solutions.

    AI Engineer
    TECH
    June 2024 - August 2025 (1 year and 2 months)
    Sydney, Australia
    Architected a multi‑agent conversational AI platform using FastAPI, LangChain, and LangGraph; implementing LLM-driven
    intent routing, context summarization, and dynamic workflow branching to reduce irrelevant agent calls and improve response
    relevance.
    • Engineered automated chart generation and data retrieval pipeline (SQL + vector similarity search) that transforms natural
    language queries into structured insights and frontend-ready visualization configs, accelerating analytical turnaround time.
    • Designed and enforced robust state management with checkpointed graph execution (PostgreSQL) and background memory
    summarization, enabling persistent conversational intelligence and lowering token usage via strategic history compression.
    • Implemented human-in-the-loop decision agents (table selection + interrupt handling) and context sufficiency evaluation,
    increasing accuracy of downstream retrieval and reducing unnecessary database scans across multi-tenant datasets.
    • Refactored and stabilized asynchronous API endpoints with resilient error handling, type-safe state propagation, and structured
    JSON outputs (including chart configs), improving system reliability and integration readiness for production deployment.

    AI Engineer
    TECH
    September 2024 - October 2025 (1 year)
    Texas City, United States
    Designed and implemented an AI-driven proposal generation platform (FastAPI + LangChain/LangGraph + OpenAI) with multi
    agent workflows (intent routing, RAG retrieval, structural drafting, reflexion/critic loop) to automate RFQ/RFP response creation.
    • Built scalable retrieval architecture using PostgreSQL + pgvector and optimized document ingestion (PDF parsing, Google
    Drive/Docs integration, semantic chunking) to enable high‑relevance, low‑latency context retrieval for generation.
    • Engineered performance layer with Redis caching, Celery background/periodic workers, and database connection pooling; cut
    repeated query and generation latency dramatically while supporting asynchronous long‑running tasks.
    • Delivered production-grade DevOps: Dockerized micro-services, blue‑green deployments via Nginx, and a GitHub Actions
    CI/CD pipeline (tests, security scanning, load testing, automated rollback) enabling zero‑downtime releases and rapid iteration.
    • Enforced robustness and observability with Pydantic‑validated LLM outputs, health & metrics endpoints, cache/stat introspection
    APIs, structured logging, and database optimization routines (index & full‑text strategy) to sustain growth and maintain reliability.
