Waqar Mobeen

Senior Frontend Engineer — React, TypeScript & design systems

12 years building multi-tenant product platforms. At Chalkline I cut page-load time by ~50%, built the 50+ component design system its Design, Product and Engineering teams ship on daily, and mentor the engineers extending it.

Things I've designed the front of and shipped.

Primary case study01

Northstar UI

Accessible React design system

A React and TypeScript component library for SaaS dashboards and complex web apps — around 40 accessible, theme-able components built on design tokens, with composable APIs and full Storybook documentation.

Role

Design, architecture, and implementation

Context

Product teams kept re-litigating spacing, colour, focus behaviour, and keyboard interaction on every screen. Northstar UI exists so they don't have to — it is engineering documentation, not a marketing page.

  • Accessibility is the baseline, not a feature: every component ships with correct roles, names, states, keyboard support, and focus management, preferring native elements over ARIA.
  • Composition over configuration: components expose small, predictable APIs and split into subcomponents (Card.*, Tabs.*, Table.*) rather than growing prop lists.
  • Tokens, not magic numbers: colour, spacing, radius, type, motion, and elevation all come from CSS custom properties — structural tokens stay fixed while colour tokens drive theming.
  • Predictable state: stateful components follow one controlled/uncontrolled contract via a shared useControllableState, so value / defaultValue / onChange behave the same everywhere.
  • Documented and verified with Storybook and Chromatic visual regression, released through CI.

    Senior Front End Developer · Chalkline

    Full-time

    On a four-person front-end team building Chalkline's multi-tenant React and TypeScript platform — white-labelled free-to-play sports prediction games serving 20+ operator clients and 100K–500K monthly active players at peak season.

    • Own front-end delivery of game experiences (Pick'em, Quick Picks, VIP Sports, Sports Bingo, Same Game Parlay) reused across every operator deployment.
    • Built the multi-tenant architecture — one codebase with per-client theming, config, feature flags, and auth modes — that lets new operators launch in days instead of weeks.
    • Cut bundle size and page load time by roughly 50% through code splitting, Webpack chunk tuning, and bundle-analyzer-driven cleanup.
    • Built and migrated the Chalkline Design System — 50+ components in Storybook with Chromatic visual review — into the single source of truth for Design, Product, and Engineering.
    • Set up the full test pyramid (Jest, React Testing Library, Cypress, Playwright visual regression), enabling multiple confident production releases per week.

About

I care about the parts users never think about.

I'm a frontend engineer based in Rawalpindi, Pakistan, working remotely with teams across the UK, US, and Europe. For the last 12 years I've focused on one thing: the layer people actually touch — and making it fast, accessible, and pleasant to work in.

That has meant multi-tenant React platforms serving hundreds of thousands of players, checkout flows for one of the UK's busiest retailers, and design systems that become the single source of truth for whole product teams. I care about the unglamorous parts — bundle budgets, focus order, predictable component APIs — because that's what makes an interface hold up under real traffic.

I'm currently open to senior frontend and engineering roles on remote teams.
