I reduce friction and create
more traction.

Engineering leadership is a whack-a-mole game. My experience across engineering, product, and AI and Agile transformations helps me hit the right mole.

I’m MJ, and I’m stubborn about making an impact.

Thirty years ago, I edited an MS-DOS binary to reverse-engineer it and translate its English commands into Czech. 😀 I got hooked and have worked in IT ever since.

Unlike many engineering leaders, I started my career as a designer, product manager, and entrepreneur, gradually using technology as a way to solve customer problems. Don’t get me wrong, I love technology. But I enjoy solving business problems even more.

A few interesting facts:

  • I spent four years living and working in the UK, including contracting for Google and Alibaba.
  • I’ve worked with teams on every continent except Antarctica.
  • I’ve taken several courses more than once to learn from different trainers’ experiences and perspectives.
  • 15 years ago, I was heavily involved in the Czech agile scene, organizing meetups, conferences, and retreats.

Increased delivery throughput
300%
Reduced L2 support MTTR
−35%
Reduced non-COGS
−50%

The wider remit

  • Led a product organisation of approximately 80 ICs and $80M+ ARR.
  • Protected $5M+ in at-risk ARR and increased retention from 80% to 92%, making qTest the company’s lowest-churn product.
  • Made qTest the company’s most secure and cloud-native offering by setting technical direction across scalability, resilience, data isolation and observability.
  • Tripled roadmap delivery throughput and reduced support MTTR by 35% by leading the shift to an AI-native software development lifecycle.
  • Embedded AI from discovery and specification through code review, security, testing, deployment and operations, and deployed autonomous agents to eliminate toil and fix bugs and L2 tickets.
  • Accelerated AI product innovation by creating a startup-like team outside the legacy organisation to move faster and earn Gartner recognition.
  • Cut non-COGS spend by 50% ($500k a year) by adopting ephemeral environments and moving testing from the cloud to local hardware.
  • Reduced release cycles from months to hours by leading an organisation-wide transition to continuous delivery.
  • Shifted engineering from firefighting to systematic root-cause remediation with a dedicated team.
  • Platformised shared data and event infrastructure for use across products and customer integrations.
