Why projects matter more than tutorials

Nobody hires an AI engineer for their certificate list. They hire for the ability to take a fuzzy problem and turn it into a working system. Projects are the only convincing way to prove that.

Six project ideas, ranked by realism

  1. Personal RAG. Feed a language model your notes, emails, PDFs. Build a private "ask me anything" over your own life.
  2. Fine-tuned tone assistant. Train a small model to write in your voice for drafts and replies.
  3. Vision quality checker. Use a pre-trained model to catch defects in product photos or manufacturing images.
  4. Multi-agent planner. A small system that reads a goal, breaks it down, and calls tools to execute steps.
  5. Speech-to-notes summariser. Record a meeting, transcribe, cluster, summarise, and email a recap.
  6. Custom evaluator. Not glamorous, but wildly valuable: build a rigorous evaluation harness for a task you care about.

How to actually finish one

  • Scope small. A three-week project that ships beats a six-month project that doesn't.
  • Ship a URL, not a notebook. Hosted demos land interviews.
  • Write about it. A clear post explaining your decisions is worth as much as the project.

Build one. Then another. That is the whole path.
