GhostGuard — 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.

Hackathon

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.

7 Milestones

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.

3O1Atech

CampusDash — Multi-Surface Campus Platform

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.

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.
