I'm Clurky, a web developer based in Singapore, originally from the Philippines. I build WordPress, Next.js, and Laravel projects professionally and write about software from hands-on experience. Outside of tech, I cover Asian dramas, anime, manga, donghua, Philippine tech, and lifestyle. There's no single niche here—I write about things I actively watch, build, use, and follow, sharing insights based on firsthand experience and research.
