What I'm looking for

I seek senior engineering roles focused on AI-driven product features, technical leadership, scalable systems, and collaborative, growth-oriented teams.

I am a Principal Software Engineer with deep full-stack and AI expertise, building production AI workflows that drive measurable user and business outcomes. I have led and scaled teams while delivering features like automated customer support handling 70% of traffic, character chatbots, AI chapter recaps, hyper-personalization, and social-agent video generation.

My background spans startups and product teams across Ruby/Rails, Python, TypeScript, React, and cloud platforms (GCP/AWS/Kubernetes), plus practical experience with LLMs, RAG, LangChain, and large-scale backend systems. I combine hands-on coding, architecture, team leadership, and product-oriented thinking to ship reliable, quality software.
