RAG, LangChain & LangGraph: The Modern AI Stack

We’ll explore three technologies that are widely used when building applications with large language models: RAG, LangChain, and LangGraph. We’ll start with RAG (Retrieval-Augmented Generation) and look at how AI applications can retrieve information from documents and other data sources to provide more relevant and grounded responses. From there, we’ll explore LangChain, including how it helps connect LLMs with data, tools, prompts, and other components needed to build useful AI applications. Finally, we’ll dive into LangGraph and see how it can be used to build more advanced, stateful workflows and AI agents that can take multiple steps, use tools, and maintain context throughout a task.

Building an AI-Powered 3D Game with Three.js

What happens when you combine AI engineering with 3D game development? That question inspired this project. I wanted to explore how far I could push a browser-based game using modern web technologies while keeping it lightweight, interactive, and fun to play. Using Three.js, TypeScript, Node.js, WebSockets, and AI-driven game logic, I built a 3D game that runs directly in the browser. The project combines real-time gameplay, 3D graphics, multiplayer communication, and intelligent game behavior into one experience. More than just building a game, this project gave me an opportunity to experiment with how AI can make game worlds feel more dynamic and responsive. It also showed me how concepts from AI engineering can be applied outside traditional machine-learning applications and brought into interactive experiences like games.

Bring Your Best Self: Mastering Behavioral Interviews

After this session, you will know how to structure behavioral responses that hold up under follow-up questions, identify which stories from your experience map most cleanly to common competency frameworks, and recognize the specific signals that tell an interviewer you are self-aware and coachable. We will work through the STAR method not as a template but as a thinking tool, so your answers feel honest rather than rehearsed. Attending live means you can bring a real answer you have been working on and hear direct feedback on what is landing and what is getting in the way, which a recording simply cannot replicate. The coach works with candidates on behavioral interviews regularly and will share the patterns that consistently separate strong responses from forgettable ones, giving you a clear picture of how this thinking applies to your own preparation.
