Some questions you may have:

  • I have been all of them as I have had diverse roles in my career. I began as a software engineer, progressed to a tech lead, and eventually transitioned into a role focused on supporting and developing individuals, culminating in my a position as CTO.

    It's challenging to provide effective support to engineers without a comprehensive understanding of their work. That's why I believe a strong leader should remain technically involved and hands-on.

    For the past 10 years, I dedicated several hours per day to coding/hands-on work.
    This practice also aids me in staying abreast of the latest technologies and maintaining a sharp focus on strategy.

  • I have a deep appreciation for people, relishing in their growth. I find fulfillment in coaching and mentoring, and I would describe my leadership style as enlightened.

    I also value simplicity and actively strive to follow the KISS (Keep It Simple, Stupid) principles, particularly in the technology domain. I've observed numerous instances of over-engineered systems that ultimately lead to failure.
    I am a pragmatic and down-to-earth individual with high standards, particularly when it comes to serving customers.

  • Employment at Meta provide me with exposure to exceptionally intricate challenges and an immense scale that was beyond reach in my previous role.
    In my pursuit of growth and learning, I couldn't resist the opportunity to collaborate with the world's most brilliant engineers.

    To me, the emphasis is placed on learning rather than a job title.
