Media & speaking

For podcast hosts, editors, and event organizers: a short bio, the topics I can speak to with working code and papers behind them, and where to read more.

Short bio

Ahmed Jaffar works in technology advisory in Toronto and is a co-founder of Fibonacci IT. He builds open source AI, data, and fintech software, and writes about the real cost of AI inference, evaluation, and security side channels. Computer science, Western University.

Topics

Cost per accepted answer. Why token price is the wrong unit for AI cost, and how to measure what a kept answer actually costs, retries included.

Can a microphone hear you type? Acoustic keystroke side channels, what the signal can and cannot do, and how to evaluate defenses honestly.

Building in the open. Shipping research-grade tools as a solo builder: reproducible experiments, honest limits, and docs that say what is not proven yet.
