What I'm looking for

I want to build end-to-end products where I can ship scalable SaaS and production AI—owning architecture, reliability, and integration from MVP to production with cross-functional teamwork and real impact on revenue and user growth.

I am a Product-Minded Senior Full Stack Engineer specializing in building scalable SaaS platforms and AI-driven systems. With over 8 years of experience, my work focuses on bridging modern web technologies with intelligent, production-grade architectures—ranging from high-performance real-time applications to advanced LLM-powered multi-agent platforms.

My professional journey is defined by end-to-end ownership, leading products from MVP to scalable production. I have contributed to and led the development of systems across diverse domains, including creator marketplaces, AI-powered tools, and data-driven SaaS platforms.

Currently, I focus on engineering AI-integrated applications, designing LLM-based workflows, function-calling systems, and human-in-the-loop agent architectures. I remain committed to building reliable, scalable, and intelligent software at the intersection of modern web development and applied artificial intelligence.
