About Me
Experienced software engineer who loves diving into new challenges and figuring things out quickly. I'm good at leading teams and finding solutions that work for everyone. Always learning and staying up-to-date with the latest tech - I can jump into unknown technologies and whip up prototypes or research solutions fast. These skills are perfect for startups where you need to move quickly and adapt. Over 9 years of professional software engineering experience across Paprikash Studio, DashBouquet, and Canva, I've led the full development cycle on more than 10 projects, making sure everything meets high standards and business goals.
