Senior SDE - Fullstack at Yellow.ai
Hi, I'm Affan, Full Stack & AI Engineer and ex-Founding Engineer at Kerjago.id. With 7+ years of experience building scalable platforms, I specialize in Backend, Frontend, Mobile, AI, and Product Engineering. I'm passionate about AI, Blockchain, and business-driven software solutions.
I work mostly with Go, TypeScript, and the React ecosystem, and I write to make complex things feel simple. I started learning software development during the pandemic out of boredom, and it turned into a passion.
