OBJ. — About
Hi, I’m Vibol Sovichea or Sovichea, Full-Stack Developer who loves the challenge of building systems that actually think. Over the last 4 years, I’ve specialized in the Next.js and Nest.js ecosystems, focusing on where secure architecture meets AI. Whether it's crafting RAG-based pipelines or developing high-impact FinTech tools, I’m driven by the goal of making complex tech feel simple and reliable for the people using it.
