jessezhang.org

jessezhang.org is the personal website and technology playground of Jesse Zhang, a distinguished engineer, entrepreneur, and angel investor with a background in AI/ML and web engineering from Harvard. This platform is not a single commercial product but rather a curated collection of innovative and experimental projects that demonstrate the practical application of cutting-edge technologies. Jesse's experience, including founding a YC-backed startup acquired by Niantic and investing in leading AI companies like Pika and LlamaIndex, lends significant credibility to the advanced concepts showcased here. The portfolio serves as both an inspiration and an educational resource for developers, researchers, and tech enthusiasts.

The centerpiece of the AI demonstrations is the 'Custom GPTs' project. This tool exemplifies the power of Retrieval-Augmented Generation (RAG), allowing users to feed diverse data sources—such as specific scientific papers or podcast transcripts—into a Large Language Model (LLM). The result is a highly specialized chatbot capable of answering nuanced questions based on the provided knowledge base, effectively turning the LLM into a subject-matter expert.

How to use jessezhang.org

Each project on jessezhang.org is an interactive web application. For the 'Custom GPTs' demo, the original workflow involved connecting a data source via a simple command (e.g., providing an ArXiv paper ID). Users could then engage in a conversation with the AI, asking detailed questions about the content. For the 'ZK Mastermind' game, users play the classic code-breaking game, but with a cryptographic twist. After each guess, the system returns feedback along with a Zero-Knowledge Proof (ZKP), which mathematically guarantees the correctness of the feedback without revealing the secret code. Other projects, like the multiplayer games 'Camel Up' and 'Bananagrams', are accessible directly in the browser, allowing users to create or join game rooms and play in real-time.

Core Features of jessezhang.org

• Custom LLM Knowledge Integration (RAG): A powerful demonstration of how to augment LLMs with custom, private data sources to create specialized AI assistants for research, analysis, or customer support.
• Zero-Knowledge Proof (ZKP) Application: A practical implementation of ZKPs in a gaming context, showcasing how this technology can ensure verifiable and private computations.
• Real-time Multiplayer Web Applications: Fully functional, browser-based multiplayer games built with modern web technologies like WebGL (for 3D graphics in 'Camel Up'), demonstrating expertise in real-time communication and complex state management.
• Interactive Data Visualization: The 'Financials Visualizer' tool provides an elegant interface to parse and display data from the 10-K financial statements of publicly-listed US companies.

Use Cases for jessezhang.org

The projects on this site, while demos, highlight powerful real-world applications. Researchers and students could adapt the Custom GPTs concept to build a personal research assistant that has deeply read a specific corpus of literature. Developers interested in Web3 and privacy-enhancing technologies can study the ZK Mastermind demo as a tangible example of ZKPs. Full-stack engineers can draw inspiration from the complex architecture of the real-time multiplayer games. Entrepreneurs can explore these demos to brainstorm new product ideas that leverage these emerging technologies for novel solutions.

Advantages of jessezhang.org

The primary advantage of jessezhang.org is its ability to make abstract and complex technologies tangible and understandable. It bridges the gap between theoretical knowledge (like ZKPs and RAG) and practical, interactive applications. The projects are developed by a credible and experienced professional, ensuring a high level of technical quality. As an open and free resource, it provides immense educational value and serves as a source of inspiration for the global tech community, demonstrating what is possible at the forefront of AI and web development.
