Teger AI
Explainable social-engineering and phishing detection for Gmail and Slack: a Chrome extension and API that surface manipulation tactics, the cues behind them and a safe next action. MVP v0.2, private beta.
AI Safety · Python
SPD Mechanism Clustering
Mechanistic-interpretability research: the first systematic empirical study of automated mechanism clustering for Stochastic Parameter Decomposition (SPD). Seven experiments from toy models to a real grokked transformer, showing component specialization — not clustering-signal choice — is the binding constraint. Paper + reproducible code.
AI Safety · Python
Reward-Generalization Early Warning
Reproduces unintended reward generalization (the OpenAI 'goblin' dynamic) in a controlled model and tests whether internal signals can flag reward spread before it surfaces in outputs — a follow-up to OpenAI's alignment research.
AI Safety · Python
Deception Feature Universality
Cross-architecture interpretability study finding statistically significant representational universality (CKA 0.56 vs null 0.26, p=0.024) for deception cues — evidence that different models represent phishing/social-engineering concepts similarly.
TypeScript
GeoDrill
AI-powered geological drilling intelligence platform — scores drilling probability across a region and renders a live risk heatmap.
Arduino · C++
Motion-Sensing Alarm System
Arduino-based motion-sensing alarm using a PIR sensor and buzzer to detect movement and trigger an alert.
Python
mechinterp-phishing-probe
Mechanistic interpretability to detect social-engineering circuits in LLMs.

About
AI, engineering & entrepreneurship.
I'm Emmanuel Effiom Duke (also Emmanuel Duke), an AI engineer, mechanical engineer and technology entrepreneur. I hold a B.Eng. in Mechanical Engineering from the University of Nigeria, Nsukka, and I'm the founder of Dukers LTD.
AI engineering and safety. I build AI products such as Teger AI, which targets psychological manipulation in messages. I also run mechanistic-interpretability research on how models represent deception and reward, published as open, reproducible code.
Software and cybersecurity. I ship full-stack products in fintech, agriculture, geospatial and security. They include AxiosPay, a cross-border FX app that placed 4th at the Interswitch × Enyata Developer Hackathon.
Engineering research. My mechanical-engineering work covers CFD modelling of steam-plant feedwater heaters, machine-learning energy optimisation and air-quality management, presented at international conferences.
Community. I mentor African founders through the Tony Elumelu Foundation and lead growth for The Upskill Space, a youth digital-skills academy.
