What I'm looking for

I’m looking for a seat where I own the entire technical vision, build end-to-end with speed in ambiguity, and ship production AI systems with real scale.

I’m an AI engineer and full-stack developer with 5 years of experience across multiple startups, consistently acting as the core technical person who builds from zero. I architect and ship AI-powered platforms end-to-end—designing system architecture, building RAG pipelines and LLM integrations, and delivering React/React Native frontends plus Python/Node backends.

In my recent role as a founding product engineer, I helped pioneer an AI-powered real estate platform, including a voice-first AI assistant that integrates directly with zipForm, multimodal generation with RunwayML/Modal, and AI recommendation algorithms for personalized property suggestions. Earlier, I built a TB screening acoustic AI app with 94% detection accuracy, created an offline-first React Native experience for rural settings, and designed systems spanning OCR, semantic search, secure data handling, and deployment-ready infrastructure—always with a bias toward speed, architecture, and real-world scale.
