"Defending global systems since 1999."
Albert Cheung has been breaking applications professionally since 1999 — legally, and for organisations that cannot afford to get it wrong. Over 25 years and 200+ assessment projects, he has stress-tested systems in highly regulated industries, aviation, banking and government among them, across Hong Kong, Singapore and Canada.
His specialty is the work tools cannot do: understanding how an application actually behaves, and knowing where an attacker pushes first. He hasn't just run assessments — he has designed the testing methodologies assessment teams run on: how web, API and infrastructure testing should be structured, sequenced and judged.
At Hack Circuit there are no hand-offs. The person you brief is the person who tests, and the person who signs the report. That person is Albert.
"Decoding the language of the markets."
Avis has invested through two decades of bull runs, crashes and everything in between — across stocks and real estate. She doesn't teach tips. Her workshops teach the actual tools: technical chart patterns, market statistics, and the reasoning behind a position — so participants leave able to analyse a market themselves, not follow someone else's call.
At Hack Circuit, she turns raw market data into investment logic people can use. Twenty years of doing it herself is the curriculum.
Assessments across web platforms, mobile apps and cloud infrastructure, using the same manual, attacker-minded approach — because in regulated industries, "the scanner found nothing" is not an assurance anyone can sign.
Offensive Bootcamps and Mastery Labs for people who learn by doing. Led by a practitioner with 25+ years in the field; theory is kept to what the next exercise needs.
Small-group sessions (up to 10) on technical frameworks and the statistical behaviour of markets, taught with a disciplined, veteran-led mindset.
