Selected work
EventPorte · Payaza
I led the rebuild of Payaza's ticketing and payments platform, including creator wallets
that trace every balance back to its transactions, and an embeddable widget that lets
organisers sell tickets on their own websites. It shipped with
zero rollbacks and brought in 32 new clients.
A Google Docs-style editor for web and mobile, with real-time collaboration, permissions
and folders. I built the editor with Tiptap and Remirror, shipped translations across
the product, and added error tracking that cut production incidents by 45%.
I architected the event-ticketing system and led a five-person team to ship it. I also
built the design system, which cut development time by 25%, and was
promoted to Senior.

How I use AI
I use Claude Code and Cursor every day. AI makes me faster; it doesn't decide what ships.
I hand off scaffolding, large refactors, first drafts of tests, and
chores like image optimisation and SEO setup.
I keep product and UX decisions, architecture, anything that touches
money, and every commit.
I check it with strict TypeScript, lint and CI. Checks are never
switched off to make an error go away, and I review every diff myself.
I debug locally first. When an AI-suggested fix for an embed bug grew
into deploy-and-check-logs, one local curl found the real cause: a double
slash in a URL. Now the shortest local repro comes before anything else.
