About

I'm a Software Engineer at Poshmark with 5+ years of experience building and modernizing large-scale web products, with a focus on frontend architecture, performance engineering, product redesigns, platform migrations, and developer experience. At Poshmark, I have been a core contributor to the Vue 2 to Vue 3 migration, SSR modernization, Node.js upgrades, Webpack and Vite developer-experience improvements, Content Security Policy rollout, and major product initiatives including the Poshmark Web Redesign, Posh Shows, Consignment, 1P Ads, and Project Gemini. Core skills: AI product development, LLM integration, agentic workflows, prompt engineering, React, Vue.js, Next.js, TypeScript, Node.js, GraphQL, SSR, web performance, Webpack, Vite, testing, web security, and CI/CD. Alongside my professional work, I'm actively developing AI-powered products through personal projects and continuous self-learning. My focus includes LLM integration, agentic workflows, prompt engineering, structured outputs, semantic search, embeddings, RAG, privacy-conscious AI architecture, and AI-assisted development. My AI work is product-focused: I explore how AI can solve real user problems, improve workflows, and create useful, trustworthy experiences rather than adding AI for novelty. I currently experiment with Claude, Cursor, Jules, OpenAI and Anthropic APIs, Transformers.js, Vercel AI SDK, and LangChain.
