AI and ML projects worth building
Reading a syllabus and having built something are different states, and only the second one survives an interview. These are staged builds rather than repositories to clone: every step says what you build, how to tell it works, and — where a line loses you — exactly which section teaches it.
Build your own GPT
7 stages · 24hA decoder-only transformer you wrote yourself, trained on text you chose, generating new text — no framework magic, about 300 lines.
AI Engineer · ML Engineer · Research
Start buildingRAG with citations you can check
7 stages · 23hA question answering system over documents you supply, which answers only from the text it retrieved, cites the chunk behind every sentence, and declines when nothing good came back.
AI Engineer
Start buildingAn agent that uses tools
7 stages · 21hAn agent written as a plain loop you own — no framework — that calls tools, survives them failing, knows when to stop, and leaves a transcript you can read afterwards.
AI Engineer
Start buildingAn eval harness that fails the build
7 stages · 24hA dataset built from real traces, graders checked against human labels, a runner that scores a change, and a CI job that turns a pull request red when quality drops.

Start buildingFine-tune a small model
7 stages · 26hA small open model adapted with LoRA to a task you define, measured against the two honest baselines — the base model, and the base model with a good prompt — and an adapter you serve.
ML Engineer · AI Engineer
Start buildingTake a model from a table to an endpoint
8 stages · 26hOne classical supervised model carried through the whole lifecycle — messy table, honest split, defended metric, tuned model, served endpoint, drift monitor — with no deep learning anywhere.
ML Engineer
Start buildingServe a model, then make it cheaper
7 stages · 24hA model behind an HTTP API that you have measured honestly, then made faster with batching, caching and quantization — with the numbers for what each one bought.
