Headless CMS admin panel

Role
Frontend developer (React)
Period
May 2022 — present

A cloud headless CMS: a control panel for content, forms and integrations that clients build their web and mobile apps on top of. I own the frontend of the admin panel — a large SPA in React 19 and TypeScript — working alongside designers and backend engineers.

Most of the work is not CRUD forms but interfaces with genuinely involved logic: a recurrence builder for dates and times, tables with a large number of states, real-time collaborative editing, a visual editor for relations between entities.

The work does not stop at the interface: I own the translation pipeline, the documentation and the tooling around it, and I step in for backend engineers on Node.js and PostgreSQL when needed.

What I did

  • Admin panel interfaces from Figma mockups to production: components, pages and backend API integration.
  • Pages with genuinely involved logic: a recurrence builder for dates and times, tables with filtering, sorting and a large number of states, JSON Schema form builders (RJSF).
  • Real-time collaborative editing on CRDT (Yjs, y-websocket, y-webrtc) with state synchronised between users.
  • A visual editor for schemas and relations on React Flow (@xyflow), an embedded Monaco code editor, dashboards on ApexCharts and Chart.js.
  • System localisation: i18n plus an in-house translator for interface copy built on the OpenAI API, replacing hand-maintained dictionaries.
  • Documentation in Docusaurus and the tooling around it: video walkthroughs generated with Playwright — a script drives the real system and records the clip, so the footage does not go stale after a redesign.
  • Retrieval-augmented generation over the documentation for an in-app chat widget: users ask a question and get an answer linked to the relevant section.
  • Migration of a legacy vanilla-JS site to Next.js.
  • Visual and end-to-end testing: Storybook with Playwright, maintaining the component library, code review.
  • Backend work on Node.js and PostgreSQL from time to time, standing in for backend engineers when the team needed it.

Interface

Recurrence builder: a calendar for picking days, weekly, monthly and yearly repeats, time intervals with a step and exceptions
Visual integrations editor on React Flow: a node palette, an order-processing graph and a debug panel
Page editing: tabs for data, categories, attributes and blocks, plus a nested category tree
