The video follows four chapters: who I am—Rithy Bondeth, a Full Stack Developer and AI Engineer in Phnom Penh with 3+ years of experience; what I do—build web platforms, mobile apps, and AI systems; technologies I use; and proof in seven projects. It features Apsara Talent, Apsara Assistant, Apsara Agentic, Apsara Elearning, Apsara Wallet, Romlerk, and Bondex Notch. New project previews fill their frames, while moving lines and shapes connect each project. The soundtrack is original and instrumental, without narration.
About my work
Passionate about building things that matter.
I'm Rithy Bondeth, a full stack developer and AI engineer based in Phnom Penh, Cambodia. I'm passionate about building high-quality digital experiences across web and mobile platforms.
I specialize in modern Typescript ecosystems (React, Next.js, Vue, Nuxt.js, Nest.js) and Python-based AI/ML workflows, with experience shipping products from internship to freelance to full-time at Digital Economy Business Committee under Ministry of Economy and Finance of Cambodia.
I believe the best technology is invisible — it just works, and works beautifully.
