01Work history

Things I’ve built, and what they had to survive.

AI video tooling, a property marketplace at national scale, and an open-source messaging platform. Different products, same job: own it end to end and keep it fast.

Tech Lead · Product Development · Remote

Leading product development on a web-based AI subtitling and translation video editor.

I own a large share of the platform end to end — the file system, the video editor, the mobile experience, billing, and the performance work underneath all of it. Built with React, Node.js and MongoDB.

  • Designed and built the entire file and folder management system — nested folders, drag-and-drop organisation, move/rename/delete, and search — writing both the frontend and backend for desktop and mobile.
  • Created the whole mobile platform for the video editor in React and Node.js.
  • Cut page load times to under half through lazy loading, Vite bundle splitting, static-page caching, and CDN configuration for large file delivery — with measured gains in LCP, CLS, TBT and TTFB.
  • Designed and built almost all landing pages with performance in mind, doubling search results within a few months.
  • Extended the video processing service using Remotion on both frontend and backend, making the editor more robust and the output quality better.
  • Integrated the GST registration API and built an automated invoicing system across frontend and backend, alongside other payment features.
  • Instrumented analytics and conversion tracking with GTM and GA4 — custom events for login clicks, scroll depth and engagement.

Happy to walk through architecture decisions, trade-offs, and the things that went wrong on any of these.
