Web Development intermediate

Accessibility Engineering for Web Applications

Accessibility is a set of engineering constraints, not a checklist bolted on at the end. Semantic structure, keyboard operability, ARIA for dynamic regions, focus management in modals, and testing with an actual screen reader rather than a linter.

Evaluation-Driven LLM Development

Shipping an LLM feature without an eval suite is shipping a rumour. Build golden datasets from production traffic, write graders that correlate with human judgement, and wire regression gates into CI so a prompt change cannot quietly degrade quality.

Data Engineering with dbt and Modern SQL

Treat analytics code like software. Layered model architecture, incremental materialisations, snapshots for slowly changing dimensions, data tests as contracts, and documentation that stays current because it is generated. Includes CI that blocks a merge when a data test fails.

Machine Learning beginner

Statistics for Machine Learning Practitioners

The statistical intuition that separates practitioners from people running library calls. Sampling distributions, confidence intervals, the multiple-comparisons trap, effect sizes, and Bayesian reasoning about uncertainty. Written for engineers who need to interpret an experiment, not to prove theorems.
