About Me

Sean Wang - Backend Developer

Sean Wang

a Full-Stack Developer and Cybersecurity Specialist

Hi, I’m Sean Wang — a Full-Stack Developer and Cybersecurity Specialist based in Australia, with a Master’s in Cybersecurity and a passion for building reliable, secure systems.

I started out tinkering with hardware and building my own NAS. Since then, I’ve designed scalable appointment platforms, migrated legacy data into PostgreSQL, and built secure self-hosted cloud infrastructure using Docker and FortiGate firewalls.

I specialize in full-stack development using React, PostgreSQL, and Node.js — with security-first architecture at the core. Whether streamlining operations for small businesses or hardening cloud access, I deliver solutions that create measurable impact.

Worksheet Generation
A dynamic Excel-based calendar system built with VBA, designed to automate daily schedule creation and holiday visualization. Users can define a custom date range and exclude specific dates, which the tool uses to generate individual daily sheets from a predefined template. The current day is automatically highlighted, and holidays are managed via a dedicated "Holiday" sheet — allowing color-coded labels and flexible tagging.
