I build the screens where a wrong number is noticed in seconds.

The page a customer pays through. Going zoneless meant deleting a component library rather than licensing it onto a payment form.

Angular 22, signals, zoneless, native dialog

Three Angular majors in one pass, on a panel the desk runs live. The framework was the cheap part; 53 components changing change-detection semantics was not.

Angular 22, ag-grid 36, ECharts, vitest

Angular, RxJS, multi-chain signing

An investment-pool platform where four roles read the same numbers and may do different things with them. The origin server has no inbound ports.

Angular PWA, Caddy, Docker, Cloudflare Tunnel

vanilla JS, no framework, no build step
