I am a Full Stack AI Engineer and Creative Developer specializing in secure full-stack architecture, relational database design (with protection against SQL Injection and other exploits), and custom LLM model integrations. Known online as Saka Chowdhury (@salahuddingfx).
I'm Salah Uddin Kader, widely known as Saka Chowdhury (salahuddingfx) — a Full Stack AI Engineer, Creative Developer, and Database Designer based in Cox's Bazar, Bangladesh.
I specialize in building secure, high-performance web applications using React, Next.js, and Node.js. My experience spans full-stack development, database design, securing applications against SQL Injection and web exploits, and training/running local LLM models. I craft experiences that are visually stunning, solid under the hood, and secure.
