I'm a software engineer with a background in blockchain startups and full-stack product development. From building clean, tested frontend code at Synterneet, to redesigning and rebuilding a KYC platform from scratch, I’ve focused on delivering scalable, user-centered solutions. At SolarShare.io, I lead development to power a solar NFT marketplace. I work closely 1-on-1 with designers to bring concepts to life, and I’m passionate about crafting immersive web experiences using Framer Motion and Three.js.

ABOUT ME
ABOUT ME
WHO AM I
I'm driven by a deep curiosity for how people interact with products—combining design, marketing, and development to turn ideas into reality. I love understanding the human logic behind great user experiences and constantly push to bring meaningful digital concepts to life. Outside of work, I split my time between Thailand and Japan—either training at a Muay Thai gym or enjoying ramen in Tokyo, always drawing inspiration from culture, discipline, and everyday experiences.

Ramen is more than food for me – it’s a reminder of my time in Japan, where I found beauty in detail, calm in craft, and joy in every bowl.
