  Spent the winter term on the Ecommerce team while taking two classes. Did the summer term on the Enterprise team building APIs for the biggest clients. Learned a lot about backend and product engineering here. Also the people are fun to talk to.

  Run backend and internal tools for the Computing Students' Association. Built the data layer for a room booking system now in production across the School of Computing, shipped a RAG chatbot that handles the bulk of routine student questions, and got the merch store online. The rest of the job is code review across a 10-person team and making architectural calls that hold up through annual exec turnover.

  Spent the summer as a Web Developer at a Forbes 30 Under 30 company. Built new client sites end-to-end, and made the existing ones faster — 40% off load times through query tuning, server config, and a CDN/caching pass — more findable via structured data and SEO work (25% lift in organic traffic), and easier for the team to maintain through segmented Mailchimp campaigns and real A/B testing.
