About Me

I’m Luka — a frontend engineer and product builder. I create fast, beautifully designed web and mobile apps. I’m also interested in the backend side — so I can own the full vertical slice. My mindset is Maximum Game: focus, speed, problem-solving and delivery.

  • Speed
    Prototype in 24–48h. Fast → validate → iterate.
  • Clarity
    One clean path to value. No friction.
  • Delivery
    No excuses. Shipped > perfect.
