At TaskRabbit, I built an LLM-powered customer support assistant that helps customers find booking information, understand scheduling policies, and resolve common post-booking questions. I connected RAG workflows to help-center content and authorized booking context, with evaluation for retrieval relevance and unsupported answers.

At Red Ventures, I built backend services and lead-routing workflows for customer acquisition platforms. Earlier, I contributed to Instagram’s feed and engagement platform at Meta, and built custom applications for small businesses and startups as an Independent Web Developer.
