AI Engineer (LLM applications)

Take a customer assistant from demo to pilot at a B2B supplier: scope it, build an evaluation set before trusting it, fix retrieval, keep one customer's orders from another, make it say 'I don't know', cost it, and report honestly on the pilot.

What you'll build

Real portfolio pieces built during the course, not a certificate for its own sake. Each one is work you can show.

  • Evaluation planHow an AI assistant is judged before launch: a set of real questions with known answers, what counts as correct, what it must decline, and the result needed to go ahead.
  • Tool authorisation designHow the assistant's order lookup decides whose orders it may return: taken from the signed-in session, enforced in code, checked twice, tested against the attack that worked, and blind to instructions in text.
  • Cost and latency noteWhat the assistant costs per conversation and per month, where its slowness comes from, what to change, and what finance should budget beyond the model bill.
  • Readiness reportThe case for the CTO: what the assistant does and does not do, the evidence from evaluation and pilot, what went wrong and was fixed, the controls, the cost, and a scoped recommendation with its next gate.

Description

Every CertClue course follows the same seven-part shape: fundamentals, the role translated out of job-posting language, a real working day, the job's recurring rhythms, a multi-day simulation, the portfolio you build along the way, and a handoff into your next move. Here is what that looks like for ai engineer (llm applications).
