Built for an employer, so the code and screenshots are confidential. This page describes the problem and my contribution; the figures come from my CV.

The problem

Login problems were a steady source of support tickets, and some backend services had grown slow as the platform and its data grew.

What I did



Integrated Azure credential-based login into the existing authentication flow, keeping existing accounts working during the switch.



Refactored backend services and optimised heavy API endpoints: query tuning, eager loading and less work per request.



Worked in Scrum with QA engineers and operations stakeholders, from requirement to release.

Outcome



System performance up 20% after the refactoring.
