- About -
Senior Frontend Engineer with 6 years building production SaaS in Vue 3, Nuxt and TypeScript: booking platforms, payment flows and data-heavy dashboards serving real paying clients. Author of two published npm libraries: a Nuxt 3 component library and a Vue 3 protocol library. I own frontend architecture end to end: component libraries, state management, testing, CI/CD, API contract design with backend, and multi-client frontend architecture, several apps on a shared backend with per-client stack choices. Accessibility is a default, not a retrofit: WCAG 2.1 AA throughout, with client sites at 95 to 100 for accessibility and 100 for best practices. EU citizen, open to mid and senior frontend roles.

Ridid
Web Application
TravelTech SaaS platform for small tourist accommodations. Led frontend development and UX/UI design over 2+ years, building booking flows, channel management, invoicing, and contactless check-in from real user feedback.
Ridid Admin
Operator Back-Office Application
The back office that runs Ridid: client accounts, subscriptions and billing (PDF invoices and quotes, Excel export, daily auto-invoicing), pricing tiers, referrals, OTA connections, one-click client impersonation and a full audit log. A separate standalone application, not a feature of Ridid: its own Vue 3 SPA front end and FastAPI backend, with their own repos, pipelines and database. It integrates with the Ridid PMS through a least-privilege shared-database connection (read-mostly, with writes scoped to two client columns), so an admin-side bug cannot reach live customer data. 84 endpoints, 248 tests, Dockerised CI/CD. In production since 2026.
