SpendSense is another powerful real world use case of how to superpower existing applications using AI. In this case, I built an AI-powered recommendation engine. After being granted permission, the system outlines a "persona" based off of a user's spending, saving, and investment habits.
The system can then recommend relevant products OR learning resources that fit the exact usecase. A good saver might want to learn about investing. Someone with lots of subscriptions might want a subscriptions manager! The recommendations are tailored to each user's unique financial situation and goals.
Considering the reasoning required for accurate recommendations, I used GPT-4o-mini to power the recommendation engine. Persona assignment uses rule-based logic. All deployed to a Python FastAPI backend using OpenAI's SDK.

Imagine if a single, simple (or long and complex as needed!) prompt generated TV-ready video advertisements within 3-4 minutes. That's our VideoAI Studio! With optional product/logo reference image upload, we implemented a multi-step video generation pipeline.
Models used include GPT-4o-mini for reasoning steps (checking for relevant assets step, planning step), GPT-4 Turbo for image analysis, Flux Dev for image gen, and Flux Dev-ControlNet for image gen with reference asset. All deployed using Python FastAPI, and celery + redis task queues to scale for multiple videos and multiple users.

Viewable Remote teams drown in chat messages, and things falling through the cracks is just an accepted fact of life. SOS helps by providing AI-powered summarization, key decision and action item extraction, and semantic search (keyword weight + vector embedding comparison). It's a React Native Expo app built with remote workers in mind.
I used GPT-4o-mini for all LLM functionality, and OpenAI Text Embedding 3 Small for semantic search capabilities, allowing users to find relevant messages even when they don't remember the exact keywords used.

A collaborative canvas tool similar to Figma.
It features real-time database sync for user presence, object selection, cursor movement, and object dragging. The rest of the persisted data is handled by the Firebase store, ensuring seamless collaboration between users.
I also used this project to learn how to build my first agent. It's very basic, using the OpenAI SDK and GPT-4 Turbo to assist with object creation and even login forms! The AI assistant can help users create complex shapes and designs with simple natural language commands.
