A production-ready AI chatbot that turns uploaded PDFs into a queryable knowledge base — giving users a natural conversational interface to get context-aware answers from their own documents, with session history maintained throughout.
Next.jsReactTypeScriptTailwind CSSLangChain.jsVercel AI SDKChromaDBOpenAI EmbeddingsDeepSeek LLMExpress.js
What I Did
Built a full RAG pipeline with LangChain that turns uploaded PDFs into a searchable knowledge base — so the AI answers from your documents, not from hallucination
Wired the Vercel AI SDK to a custom streaming backend so responses appear token-by-token, giving users the feel of a live conversation rather than a loading spinner
Extended the AI beyond passive Q&A by building a tool-calling layer that lets it actively inspect the knowledge base — surfacing available documents on demand and generating on-the-fly topic summaries in the user's preferred format
Kept conversations coherent across long sessions by managing history intelligently, trimming old context automatically to control costs without losing the thread of the dialogue
Shipped a document upload flow that keeps users informed at every step — from file received to fully indexed — using real-time progress events streamed back to the UI
Cut inference costs by ~14× versus GPT-4 by benchmarking and integrating DeepSeek, while keeping the model layer swappable so any LangChain-compatible LLM can be dropped in

This Portfolio — You're Looking At It 👀
🇨🇦CA•Sep 2024 - Nov 2024
A self-aware, slightly smug portfolio website that exists solely to tell you how good its own creator is — while being good enough to prove it 😏. Features dark/light theming 🌗, buttery-smooth page transitions ✨, and enough animated statistics to make any recruiter mildly overwhelmed 📊. Meta fact: this very project card was written by the portfolio to describe itself 🪞. It has no imposter syndrome.
Next.jsReactTailwind CSSFramer Motion
What I Did
Architected a flash-free dark/light mode system 🌗 — localStorage persistence wired via an inline script in _document.js, because nobody asked to see a blinding white flash at midnight 🌙
Implemented fluid page transitions and scroll-triggered animations using Framer Motion's AnimatePresence ✨, giving the site a cinematic quality that is frankly disproportionate to its existence as a portfolio
Built a responsive navigation system with a hamburger menu 🍔 and animated mobile overlay — because mobile users deserve smooth animations too, even if it's just your mum checking the site 📱
Configured a custom Tailwind design system 🎨 with bespoke colour tokens, circular gradient backgrounds, and responsive breakpoints covering everything from ultrawide monitors to the narrowest of phones
Designed and rendered this very project card 🪞 — an act of recursion that would make a computer science professor either nod approvingly or quietly weep
