About

From Lagos to Toronto

I spent a decade leading technology and DevOps at Socketworks in Lagos, then moved to Canada and into enterprise platform engineering — multi-tenant OpenShift estates, Istio service mesh, GitLab CI/CD, and the operational constraints that come with serving carriers and financial institutions at scale.

Over the last two years my work has tilted toward AI. I build and ship production LLM and agentic systems — LangGraph supervisor-worker agents on AWS Bedrock, RAG pipelines on Vertex AI, evaluated with RAGAS. The through-line is full-stack ownership: from model integration to CI/CD, observability, and security.

The side projects are where the AI work started. African Stores Canada is an agentic system that catalogues African businesses across Canada; igbo-rag is quieter — my wife and I both carry Igbo heritage, and I am building a retrieval-grounded translator to help preserve the language for our children.

When I am not in a terminal I shoot photographs on a Sony A7III. It keeps me looking at the world a little differently.

Selected work

African Stores Canada

Personal

Helping the African diaspora find grocery stores stocking familiar food across Canada.

Production LangGraph agentic pipeline on AWS Bedrock (Claude Haiku 4.5) — typed StateGraph, native tool calling and MongoDB Atlas checkpointing for crash-resumable reasoning. The agent autonomously searches, scrapes and catalogues over 500 businesses across all 10 provinces at under $0.50 per national crawl. Live Next.js web app with a password-gated /ops dashboard and a companion iOS app on the App Store.

Igbo-English RAG Translator

Personal

Preserving the Igbo language for the next generation — a heritage project for my family.

Rebuilt on Vertex AI RAG Engine (text-embedding-005, Gemini 2.0 Flash), migrated off a local FAISS/Ollama stack and provisioned end-to-end with Terraform + OIDC. Ingested 1M curated Igbo-English pairs from a 19.5M-row NLLB dataset, reaching a RAGAS answer-relevancy of 0.833, served via FastAPI with retrieval scoring and citations.

My wife and I both carry Igbo heritage. This one is for our children.

AI Log Monitoring System

Personal

Detecting anomalies in application logs with an automated, secure MLOps pipeline.

End-to-end AWS MLOps pipeline on SageMaker Pipelines (preprocess → train → evaluate → register) deploying an Isolation Forest model with promotion gated on F1 score. Terraform-managed infra with HCP remote state and GitHub OIDC — no static credentials — and multi-stage security gates (Bandit, CodeQL, OWASP, SonarCloud, Trivy) across AKS and AWS.

No Wahala Receipt — iOS

Personal

Turning photos of receipts into structured expense data for family budgets.

Published iOS app integrating Google Gemini for OCR-based receipt scanning and automatic expense extraction. Secure auth with 2FA, email verification and role-based access for multi-tenant family accounts, plus an analytics dashboard with spending insights and export.
