Dear hiring humans,
Backend & full-stack engineer in Bali, with over a half-decade of experience building backend systems, AI-powered ERPs, and on-demand platforms. I still get excited when something finally works!
Gede Ryan Pradnya Prastika
Backend & Full-Stack Engineer
Hi, I'm Ryan — a software developer based in the beautiful island of Bali, Indonesia. I've been building things with code for over 7 years, and I still get excited every time I solve a new problem.
My journey started at Udayana University, where I studied Information Technology. Since then, I've worked across industries — from banking to on-demand services to AI-powered ERPs. I specialize in backend architecture, but I love getting my hands dirty with the full stack when needed.
When I'm not coding, you'll find me exploring new ideas through books, catching up on movies, or traveling to find new perspectives. I believe the best solutions come from understanding the world beyond the screen.
"Problem-solving interests me because it allows me to understand things more deeply and find practical ways forward."
