Aladdin Engineering Spring Intern

A spring internship with Aladdin Engineering, BlackRock’s investment and risk management platform organisation. I was selected as 1 of 12 participants from over 11,500 applicants, and ranked 1st in the Python technical coding challenge.

Editor plugin that learns internal patterns

The main piece of work was a Windsurf plugin that learns the conventions already present in an internal codebase and biases completions toward them. Generic model suggestions are often syntactically fine but stylistically foreign, which makes them expensive to review.

The plugin was adopted by the team. It lifted suggestion accuracy by roughly 25% and cut review time by around 30%. The second number matters more, because it reflects suggestions that reviewers accepted without rewriting.
