About

Professional summary

I am a Full-Stack AI Engineer specializing in production-grade LLM applications, autonomous tool-calling agents, and backend automation systems.

I build reliable AI products by combining generative models with deterministic business logic, strict JSON schemas, validation layers, and secure database workflows. My work focuses on reducing hallucinations and ensuring accurate outcomes for financial, operational, and customer-facing processes.

I have experience designing RAG pipelines, multi-turn conversational agents, WhatsApp commerce systems, subscription billing engines, and AI-powered customer support automation. I work extensively with OpenAI, Anthropic Claude, Google Gemini, Ollama, LangChain, Supabase, PostgreSQL, and n8n.

On the backend, I develop API-driven systems using Node.js, Python, FastAPI, webhooks, Docker, and event deduplication patterns. I also build payment and transactional integrations with providers including Paystack, Stripe, and TGIPay.

On the frontend, I create responsive interfaces and internal operational tools using React, Next.js, TypeScript, Tailwind CSS, Retool, and Tauri. I enjoy building end-to-end systems that connect AI reasoning, automation, data infrastructure, and user experience.

I am particularly interested in privacy-first AI infrastructure, autonomous business workflows, reliable agent architectures, and scalable AI systems for commerce and support operations.

Career history

Full-Stack Automation & AI Engineer 24Manager Ltd

Architected and deployed an 11-workflow n8n subscription billing engine for recurring Paystack charge cycles, tiered dunning workflows, automatic suspensions, and real-time subscription status management using Supabase as the system of record.

Built the Jollofull autonomous WhatsApp ordering agent using GPT-4o-mini for natural-language menu processing, TGIPay payment links, Chowdeck delivery dispatch, and Supabase-backed multi-turn conversation memory.

Created a role-gated Retool administration console that routes state-changing actions through validated n8n webhooks. Engineered idempotent inbound webhook processing to prevent duplicate charges and ghost transactions across third-party payment gateways.

Independent AI Systems Architect Freelance / DARC Automations

Built a deterministic invoice engine that separates AI-driven structured entity extraction from deterministic financial calculations and post-processing. The system was tested with 15-item, four-currency invoices exceeding ₦320M while maintaining a 0% arithmetic error rate.

Architected HomeScanPro customer support automation for a UK client, connecting Gmail webhooks, Gemini classification, Supabase ticket routing, automated acknowledgments, and Slack-based human escalation to eliminate manual triage work.

Deployed a privacy-first local LLM platform on Ubuntu using Mistral 7B through Ollama, FastAPI, and n8n tool-calling. Also developed the OpenClaw Mission Control desktop dashboard with React, TypeScript, and Tauri, and configured AI CMS pipelines for Webflow and Supabase publishing with SEO metadata automation.
