About Me

Full-stack developer and MSc Theoretical Physics student (King’s College London) with a build-fast, ship-clean mindset. I focus on performance, accessible interfaces and data-driven product decisions.

Recent work includes leading the web build for Expendid (freelancer finance platform): public waitlist with referrals/leaderboard, secure admin tools, and a responsive glass-UI shell in Flask + vanilla JS. Before that, I implemented an FDTD electromagnetic solver for modelling a ring resonator and did quantitative research at a London hedge fund (portfolio construction & risk).

  • Designed & shipped an end-to-end waitlist stack (capture → referral tracking → leaderboard) with clean admin UX.
  • Performance-first: semantic HTML, CSS architecture, and JS that degrades gracefully; aims for 90+ Lighthouse.
  • Accessibility baked in: colour-contrast tokens, focus states, keyboard flows, ARIA labels.
  • Python/Flask back-ends, lightweight APIs, and simple deploys (Render/GitHub Pages) with HTTPS & DNS.
