About
I'm a Senior Frontend Developer with extensive experience building web applications, mobile apps, and design systems. I've worked across diverse industries from Web3/NFT platforms to EV charging networks and gaming.
I enjoy solving complex technical challenges, mentoring junior developers, and architecting scalable solutions. Currently, I'm combining my love for technology and cycling as Fractional CTO at Pedale.
When I'm not coding, you'll find me exploring the latest video games, participating in hackathons, experimenting with new web technologies, or enjoying long cycling sessions. Gaming and hackathons fuel my passion for interactive experiences and rapid prototyping.
