I like building useful software, getting close to the people who use it, and following hard problems until they make sense.

    Content protection for authors, course creators, and small teams selling digital work. I’m building an AI agent that finds pirated copies across the web, verifies matches, and handles DMCA notices and follow-ups. A free piracy audit helps creators see where their work is being shared.

    Studio-quality voice, without the studio. An on-device model trained on speech strips fans, hum, traffic, and room noise from recordings, so podcasts, voiceovers, and audiobooks sound studio-clean. Then level, cut, split, and convert the results in batches. Everything runs offline on Mac, Windows, and Linux, and nothing is uploaded.
