My work experiences across different companies and roles.
• Assisted in teaching Data Structures & Algorithms (COMP2540) to 2nd/3rd-year Computer Science students.
• Conducted tutorial sessions and office hours, clarifying concepts such as arrays, linked lists, stacks, queues, trees, graphs, recursion, sorting, and hashing.
• Reviewed and graded assignments, coding projects, and exams, providing constructive feedback to improve student understanding.
• Optimized Student Services' Drupal site for mobile: reduced asset payloads and refactored templates, improving Core Web Vitals (Lighthouse mobile performance moved into 'Good' range).
• Standardized reusable components and streamlined content workflows, lowering page maintenance overhead and accelerating updates across pages.
• Completed an accessibility audit (WCAG) and resolved semantic roles, alt text, and focus issues to improve keyboard navigation and screen-reader compatibility.
• Curated STEM datasets and rubric-based evaluations for LLMs; implemented checks to verify math / code output and prevent regressions.
• Surfaced insights that guided prompt/data updates and improved model behavior.
• Co-designed and launched the organization website; improved information architecture and SEO (structured metadata, sitemap) to lift first-month organic traffic.
• Applied UX and accessibility best practices to simplify navigation and broaden reach.
