Project ideas that actually impress
What happened
A curated repo of 300+ ML system‑design case studies was posted as a source of real-world project prompts for portfolios and interviews. (github.com) At the same time, industry pieces suggest building AI-enabled demos—like sandboxed agentic payments or AI video/music tools—to show system thinking, security trade-offs, and UX integration. (thestreet.com) (arstechnica.com)
Why it matters
A public GitHub collection maintained by Bhargav Patel (Engineer1999) now aggregates more than 300 real‑world machine‑learning system‑design case studies from over 80 companies and organizes them by industry and use case so you can find production examples for recommender systems, search, fraud detection, and more. (github.com) Separately, payments and platform companies are building infrastructure that lets software programs move money without a human clicking “pay”: Google published an open framework to let programs initiate payments across platforms, and Circle launched a test network that enables tiny USDC transfers measured in millionths of a dollar. (cloud.google.com) (circle.com) “Agentic payments” means autonomous software agents — small programs that can act without a human step — conducting transactions on behalf of users or services, and Google’s Agent Payments Protocol (AP2) is an open set of rules released in September 2025 intended to standardize how those agent‑led payments are initiated and authorized across different providers. (cloud.google.com) (bloomberg.com) Google also pushed a large update to its Vids editing product that plugs in two new generation models — Veo (video) and Lyria (audio) — and adds “directable avatars,” which are controllable synthetic on‑screen characters you can script and steer during generation. (arstechnica.com) (blog.google) (9to5google.com) Turn these announcements into two portfolio projects: 1) a sandboxed agentic‑payments demo that runs on a test environment (a sandbox is an isolated setup that never moves real money) and connects to Circle’s nanopayments testnet or a mock AP2 interface, with clear modules for authentication, rate limiting, reconciliation, and an audit log to demonstrate security and correctness. (circle.com) (cloud.google.com) 2) an AI video/audio pipeline that shows end‑to‑end system thinking: a service that accepts user intents, calls a controllable video model (Veo) and an audio model (Lyria), enforces content controls and rate limits, and records provenance metadata (who requested what and which model versions ran).
