About

MiPrep AI is built by Gareth William, a Senior Software Engineer with 16 years of enterprise experience.

MiPrep AI started as a solution to a personal problem — I interviewed candidates for 16 years, and I saw every candidate scramble for the same coaching that the well-connected got for free. MiPrep AI closes that gap. Read the manifesto for the full story.

Who builds MiPrep AI?

Gareth William is a Senior Software Engineer with 16 years of enterprise Java, plus a decade of open-source work on distributed AI infrastructure. He interviewed thousands of candidates across roles from data engineer to solution architect, and saw every candidate walk in either wildly overprepared with expensive coaches or wildly underprepared and losing offers. MiPrep AI is the equalizer.

What powers MiPrep AI?

MiPrep came out of a decade building systems where 40ms of extra latency cost real money — MEV bots, HFT orderbooks, distributed training infrastructure. The interview copilot is the same core engineering pointed at a different problem: hearing a question, retrieving the right answer, and delivering it to your eyes before the interviewer finishes their sentence. Runs on Mac and Windows. Invisible on screen share. No pixels, no ad trackers, no dark patterns.

What principles do we ship on?

Trust over hype. Real measurements over marketing claims. Honest billing over dark patterns. Verified stealth over 'undetectable' promises. Named authors over anonymous 'MiPrep Team' bylines. Every page you read here has a human name attached to it.
