Bio

I am a self-taught engineer working as the Founding Engineer at Connectivia Labs, a Silicon Valley AI startup, where I architect platforms across machine learning, computer vision, large language models, and multi-agent AI systems. I work daily with RAG pipelines, LLM evaluation frameworks, and agentic orchestration in production.

I am a self-taught engineer working as the Founding Engineer at Connectivia Labs, a Silicon Valley AI startup, where I architect platforms across machine learning, computer vision, large language models, and multi-agent AI systems. I work daily with RAG pipelines, LLM evaluation frameworks, and agentic orchestration in production. Before this role, I worked as a Lead Machine Learning Engineer and built my career through hands-on practice rather than a traditional CS degree, with three years of experience building production AI systems.
I have been tutoring since 2022, primarily through Wyzant, with experience spanning elementary school through working professionals. I served as a Machine Learning Engineering Career Mentor at Springboard, where I provided one-on-one biweekly mentorship to aspiring ML engineers covering data preprocessing, model deployment, and applications of large language models and generative AI. I taught Python and game design to elementary school students aged five to nine through CodeAdvantage across three Bay Area schools. I have also worked individually with high school students on Python and robotics projects, college students on data science coursework, and adult professionals including a Yale Law professor applying NLP to international policy research and biostatisticians using machine learning for breast cancer detection.
My teaching approach is patient, project-driven, and focused on real understanding rather than memorization. I help students build intuition first because that is what makes concepts stick. I adapt to each student's pace and goals, whether they are debugging their first Python script, preparing for a technical interview, learning how to work with large language models and agentic AI, exploring data science fundamentals, or working through a personal project that has stalled. I treat tutoring as mentorship, so students leave each session with working code, clearer understanding of the underlying concepts, and a sense of where to go next.
