Ethan Ng designs and deploys AI-powered automation for law firms accounting practices clinics consultancies small businesses — so the slow, repetitive parts of your day run themselves.
I build WhatsApp chatbots that handle client enquiries 24/7, modern websites with embedded AI assistants that turn visitors into bookings, and workflow automation that quietly removes manual busywork.
No technical knowledge needed on your side. I scope it, build it, host it, and keep it running.
One person, every line of code. No account managers, no handoffs, no "let me check with the dev team." When something needs fixing, you talk to the person who built it.
Book a free discovery call ↗Automate client intake, route enquiries, answer FAQs — 24/7, in any language. Reduce the need for dedicated phone lines and manual follow-ups.
Identify and eliminate operational bottlenecks. I map your current processes, find where time is lost, and build systems that handle it automatically.
Modern, fast websites for small businesses — optimised for search and built for conversion. Every site ships with an optional embedded AI assistant that answers visitor questions and books calls around the clock.
I build, host, and maintain your AI systems. You stay focused on your business — I handle updates, monitoring, and improvements.
I handle everything technical. You tell me the problem — I identify the right solution, build it, and keep it running.
Most clients are live within two weeks.
I learn about your business, your current workflows, and where you're losing time or clients. No deck. Just questions.
I propose a specific system tailored to your needs — with clear costs, clear timelines, and clear outcomes. No vague AI promises.
I build and launch your system. You test it in real conditions, give feedback, and I refine until it's working the way you'd want it to.
I maintain and improve your system on a simple monthly retainer. No surprise invoices. No version-locked dead ends.
Five lawyers. New enquiries were sitting unanswered until someone noticed. I built a WhatsApp system that responds instantly, handles PDPA consent in English or Mandarin, routes by area of law, and books straight into the right lawyer's Outlook calendar.
More case studies will be added as engagements conclude. Book a call to discuss yours.

Ng Zhen Yang, Ethan is a Singapore-based independent technology contractor who builds AI-powered automation systems, WhatsApp chatbots, and modern websites for small businesses. He specialises in WhatsApp chatbot development, website design and development, workflow automation, and managed AI infrastructure for professional services firms including law practices and accounting firms. He operates under the trading name Ng Zhen Yang, Ethan.
Most AI services either hand you a generic chatbot and walk away, or build something complex you then have to manage yourself. He does neither — scoping the problem, building the system, hosting it, and improving it over time, so it gets more useful instead of becoming a dead end you paid for once.
He works on a monthly retainer with no lock-in, is honest about what AI can and can't do, and builds so that clients keep full ownership of their own data.
