Products I've built
AI systems, fintech infrastructure, and production platforms — solo and with my team at 3O1Atech. Cards with a demo reel open on click.
AI & Applied Machine Learning
Multi-agent systems, reinforcement learning, fraud detectionGhostGuard — AI Payroll Integrity System
Continuous AI verification layer that re-confirms every worker's identity each payroll cycle before funds are released. Four-stage gate: MediaPipe liveness (blink + head motion), DeepFace Facenet512 matching against a BVN reference, multi-signal deepfake analysis (temporal, FFT, compression artifacts), and behavioural anomaly scoring on transaction history. Built against Nigeria's ₦4tn/year ghost-worker problem.
Nigerian Multi-Agent LLM Swarm
Fourteen coordinated LLM agents across two pipelines for the DSN × BCT Hackathon 3.0 — a six-agent chain for persona-calibrated review generation and an eight-agent recommender doing cross-domain taste projection. Pluggable LLM backend (Kimi, Gemini, OpenAI, local HF), ChromaDB vector store, and a real evaluation harness measuring RMSE, ROUGE-L, BERTScore, NDCG and Hit Rate.
Project Cognition — Self-Learning Trading System
Ensemble reinforcement-learning scalping system taken from architecture doc to deployable service across seven milestones. Five DQN agents each vote through their own feature lens; a per-regime meta-learner reweights them after every closed trade. A standalone risk engine gates every order — 1% equity cap, −5% daily circuit breaker, drawdown governor — and agents cannot override it. Ships Docker + systemd deploy, nightly retraining behind a promotion gate, Telegram alerting, and a full operations runbook.
Adaptive RL Agent — CartPole
Enhanced Deep Q-Network combining Double Q-learning, a duelling architecture, and Prioritised Experience Replay, trained over ~1,122 episodes and then tested zero-shot against seven altered-physics worlds (Moon, Mars, Jupiter gravity, long pole, heavy cart, fast physics). Shipped with a Streamlit dashboard and a written academic paper.
AI PDF Reader Bot
Streamlit chatbot for interactive conversations with multiple PDFs. Extracts text with PyPDF2, embeds content, and uses LangChain + OpenAI with FAISS-powered retrieval and conversation memory for contextual Q&A.
Autonomous Crypto Trading Agent
Self-improving algorithmic trading system for the crypto market. Uses ML and real-time market data to execute trades autonomously, adapting to changing conditions. The precursor to Project Cognition.
Platforms & Product Engineering
Multi-surface products, marketplaces, business systemsCampusDash — Multi-Surface Campus Platform
A four-surface product built with the team at 3O1Atech: a customer web app, a cross-platform mobile app, a backend API service, and an internal admin dashboard — each maintained as its own repository with a shared contract between them. Currently in active development.
Academia Hub — Academic Marketplace
Two-sided marketplace for academic projects and research resources. Stripe Connect powers seller onboarding and split payments with a 15% platform commission, webhooks track payment state, and AWS S3 holds files behind signed URLs with a local-disk fallback in development. Includes buyer–seller messaging, role-based access for buyer/seller/admin, and a seller earnings dashboard.
Nine-System Software Archive
Nine independent, self-contained systems — each fully offline-first with vendored assets, each documented, and each shipping a terminal client with full parity to its web UI. Includes PhishGuard AI (32-feature ML phishing detection), SentinelIQ (credit-card fraud scoring with a live dashboard), an automated resume screener with geospatial proximity ranking and Excel export, TaskMind (NLP task capture with priority scoring), ComplaintDesk, a study planner, a discrete-event network simulator, and a student records system.
CardExpress — ATM Card Request & Delivery
Web-based ATM card request and delivery system for Nigerian banks, covering the full lifecycle from request through approval, production, dispatch and delivery — with public reference-code tracking that needs no login, agent assignment for dispatch, and a notification at every state change. Built accessibility-first for its financial-inclusion goal: keyboard navigation, ARIA live regions, and a persistent high-contrast mode.
Hospital EHR System
Electronic Health Record platform where doctors manage patients, medical records and appointments under strict row-level security — only doctors on a patient's authorised list can reach their data, and access is shared explicitly by doctor ID or email. Token-based auth via dj-rest-auth with a React + Material-UI frontend.
Client & Freelance Delivery
Shipped for real businesses, live in productionModern E-Commerce Platform
Fully responsive e-commerce platform with product catalog, shopping cart, user authentication, and mobile-first design, wired to a payment gateway for checkout.
Event Management & Booking Platform — Palmwine Merchants
Freelance-built booking platform for event discovery, ticket purchasing, and brand engagement, supporting recurring event promotion and ticket-sales workflows.
301ATech Corporate Website
Corporate website for 301ATech (software company). Modern, responsive site with clear service positioning and production-ready deployment for a strong web presence.
SLO Brand Website
Brand website built from a Figma design system into a working React + TypeScript front end, translating the handoff faithfully into responsive components.
