Full Stack Engineer at AstraZeneca who improved a planning platform and automated QA testing.

At AstraZeneca, I improved a succession-planning platform used by 1,000+ HR users, cutting page load time by about 20% with shared state and cached images.

I also built a Python and Playwright QA automation tool that returned about three hours per tester each day for a 12-person team across 20+ countries. I was the first AstraZeneca engineer to consume Snowflake's Native Endpoint, designing the data model and integration layer without an internal example to follow.

At Autocuro Technologies, I launched autocuro.com end to end as the sole developer, using React, Node/Express, and MySQL. I also designed a Python heuristic for placing variable-size PCB components under multiple constraints.

At Netways FZ LLC, I built a PowerApps app to automate employee reimbursement workflows and contributed C# API tests. At AstraZeneca, I also built and QA-tested Adobe Analytics and Tealium IQ instrumentation for enterprise reporting.
