Good software engineering, in my view, is creative work. I thrive on devising solutions, from enhancing a flow's conversion rate to fostering a positive team environment. My passion for this craft is twofold: striving for excellence and genuinely enjoying the journey. For me, the process of building software should strike a balance between challenge and enjoyment, always pushing boundaries while keeping things engaging.
