Jakub Warzecha

My Career.

From the production line to building software with AI agents.

  1. Aug 2026 - Present

    Founder & Developer

    Clickwill · Remote

    I design, build and release Clickwill, an iPod classic manager for Mac, with AI coding agents.

    • About 40,000 lines of Swift and SwiftUI, 568 automated tests and over 500 commits since August 2026.
    • Versions 0.2.1 to 0.2.6 shipped in six days in October 2026, signed and notarized, with in-app updates. Public beta since 29 October, open source under GPLv3 since 30 October.
    • Mapped Apple’s undocumented binary iTunesDB format on a real iPod, and implemented its hash58 signature from the libgpod description, cross-checked against a second implementation.
    • I make the product and design decisions and set the rules; AI agents (Claude Code) write most of the code, and every change passes the automated tests before it touches a real iPod.
    • Growth with AI: SEO for classic search and for AI answers through llms.txt and structured data, plus Google Ads.

    Assistant to Project Manager

    L-TEK (iAmats) · Wadowice

    I designed and launched the company’s customer support platform and handle daily technical support in English for customers in the US.

    • Designed and launched iAmats Support: a self-service knowledge base, a dance-pad tester in the browser, product manuals and contact forms routed to the right team.
    • Daily technical support in English, mostly for customers in the US, about 30 tickets a week across teams.
    • Set up the company’s Empik Marketplace store from scratch in September 2022 and run it: 24 products on sale and 1,000+ orders.
    • 30+ email campaigns in MailerLite, design and copy, with a 26-27% average open rate and 37% on a product launch.
    • Coordinated software projects delivered with external developers: planning, team time for up to four people, build testing on target hardware and milestone acceptance.
    • Tested and approved builds of Connect Buddy, the desktop launcher for StepMania L-TEK, and Pady Fitness, an iOS app on the App Store.
