Projects

Side projects and things I've built.

• AceSpeak ↗

  Co-founder & CIO · launching August 2026

  An AI interview and public-speaking coach built to make practice specific, encouraging and worth repeating. Our dream is to help people rediscover the joy of speaking in the age of AI — one take and one useful change at a time.

  Built intensively from June to August 2026; preparing for a late-August launch.

• Wistkey ↗

  CTO · day job

  Production AI and engineering delivery for enterprise and government. Private on-premises LLMs, multi-agent systems and workflow automation — plus the on-demand engineering teams that ship them. London HQ, delivering across the UK and Hong Kong: ten years, 120+ clients, 15+ government platforms, systems used by over 2M people.

• krystle.hk ↗

  Rebuilt it, in a weekend

  My wife's professional MC portfolio, rebuilt from a heavy WordPress stack into 102 pages of dependency-free static HTML. Lighthouse SEO 85 → 100, first paint 13.8s → 1.7s, ~5 KB of JavaScript. Written up as a five-part series on this blog.

• NamLoop ↗

  Side project

  A tool to put any YouTube video on endless loop — whole clip or a precise A–B segment — with speed control and a queue. Plays through the official YouTube embed, and every setting is shareable by URL.

• VitaBaby ↗

  Builder

  Baby health & growth tracking for parents, by Vitaledger. I build the web experience and the free tools around it.

• Baby Growth Percentile Calculator ↗

  Free tool

  A free growth percentile calculator based on WHO child growth standards. Runs entirely in the browser — no data leaves your device — and can be embedded on other sites.

There are plenty more — client work, older builds and half-finished experiments. I'll add them here as soon as I get a free weekend.
