Work Experience

Freelance Frontend Engineer

Self-Employed

Jan 2026 - Aug 2026

Designed and built the platform from scratch with Figma, Next.js, TypeScript and Tailwind CSS, delivering 3 pages, 7 homepage sections and 20 reusable components. Reached Lighthouse scores of 99 Performance, 97 Accessibility, 100 Best Practices and 100 SEO on desktop by optimizing images, fonts, metadata and Core Web Vitals. The site has had 2,000+ visitors since launch. Set up 3 integrations for ticketing (Ticket Tailor), forms (Tally) and email (Resend) for booking and enquiries.

Freelance Frontend Engineer

CineArtery

Jan 2026 - Aug 2026

Redesigned the Settings module in Figma in under a week, then rebuilt its 7+ pages and 50+ form fields in Next.js, TypeScript and TanStack Query within a month, replacing legacy code that kept refetching the same data. Wrote 15+ reusable TanStack Query hooks across 30+ REST endpoints using query-key factories, optimistic updates and cache invalidation, so revisiting a page makes zero extra API requests. Merged 4 account types (Market, Rental, Producer, Cast & Crew) into shared configuration-based components, removing 500+ lines of duplicated code. A new account type now takes under 5 minutes to add. Fixed 2 bugs that lost saved edits and showed stale data after tab switches (null handling, cache invalidation).

Closed a security gap letting users open restricted pages (e.g. HR pages) by URL, adding Next.js middleware, route guards and role-based access control (RBAC) across 100+ routes and components used daily by 300+ employees. Built 3 more features for the same app: a real-time chat frontend with typing indicators, face-recognition login using face-api.js and geofencing with Google Maps APIs.
