Things I have built.

Six working builds — Power Apps canvas apps, a Copilot Studio assistant, and the registration portal from my AI Operations Specialist capstone. Each comes with the design document I wrote for it, and most with a short video of it running.

01 Projects

City College Student Registration Portal

Capstone project for the SCTP AI Operations Specialist programme, and the largest of these builds. A self-service portal where prospective students search courses, register online, and get a Student ID and confirmation email generated automatically. A grounded AI assistant answers admissions questions from approved college sources and refers anything sensitive or unsupported to staff, while a Power BI dashboard shows registration volume and course demand.

  • Copilot Studio

Team project — built with Ng Ti Han and Steven Leong. I authored the app design document.

HR Helper Chatbot

An internal assistant that answers employee questions from the staff handbook and social media policy. It uses retrieval-augmented generation to find the relevant passages, combine them, and cite where each answer came from — and it is deliberately scoped to HR policy rather than built as a general-purpose chatbot.

Helpdesk Ticket Recording System

A ticketing prototype for logging customer issues and finding them again. Staff raise a ticket, the record is stored against an Excel Online table, and a search screen retrieves existing tickets by their details.

  • Excel Online
  • Power Fx

Delivery Tracking System

A delivery-request app covering the whole small loop: capture the customer's name, address and phone, record quantity, delivery option and whether the items are fragile, then save and search the results. Three screens — welcome, entry and search — with navigation between them.

  • Power Apps Canvas App
  • Excel Online
  • Multi-screen navigation

Hotel Booking System

A single-screen booking form that takes contact details, guest and room requirements, check-in and check-out dates, and any special requests. It validates the customer name and email before confirming, so the stored records stay consistent enough to work from later.

  • Power Apps Canvas App
  • Excel Online
  • Input validation

Employee Detail Recording System

The smallest of the five, and the clearest: one screen that takes an employee ID, name, phone number and department, writes a single record to the data source, and clears itself ready for the next entry. Every on-screen input maps to a named column.
