Tech & cybersecurity consultant + evangelist

Computer programmer since the 1970s

My first encounter with computers and programming was when I was in junior high school in the 1970s. My first computers were the Casio pocket computer, Radio Shack TRS-80 and Sinclair ZX Spectrum, and I learned BASIC on them. The TRS-80 was connected to a green monochrome monitor and we stored data on cassette tapes! I also had my eye on the TRS-80 Pocket Computer, which resembled a calculator at the time.

Apple Macintosh Evangelist & Pioneer

Remember those beige Macs with the little monochrome screens? I used those early Macs in 1986 and developed networked training software for factory technical training and customer service training software. The limitations of the small monochrome screen did not stop me, and I was able to compress and optimize graphics with image dithering, phone-quality audio, low-frame animation, and other special techniques to bring animation and interactive media to the classic Macs. For old and obsolete computers, visit, a really nostalgic and great resource.

Seamus Phan, multinational bank, 1988

I have gradually evolved with technology and kept up with its many changes. I was also put in charge of a mainframe in a bank, where I was responsible for desktop publishing (DTP). I design and develop websites (for B2B, B2C, e-learning, content delivery, and SEO), web and mobile applications (hybrid and native), social media and related applications, custom media and advertising databases, Perl and PHP scripting, and OS X consulting.

I delivered a keynote at the Board of Commissioners of Currency Singapore (BCCS, Ministry of Finance) event to launch the website I developed for them in 1996. The site was state of the art at the time, showcasing Singapore’s currencies (dollars and coins) and various educational topics about the currencies.

I have experience developing full-stack web applications, mobile applications, social media applications, e-commerce, and Apple Mac-based databases and applications.

Cybersecurity Consultant

NetJanus™ email security appliance co-developed by Seamus Phan in 2000

Together with an Australian colleague, I developed the NetJanus™ email security appliance based on the BSD UNIX platform in a small form factor. Our efforts started out of frustration with the growing problem of email spam and attachment malware in incoming email (especially spoofed email). We developed various test platform workstations and servers in portable, lightweight hardware profiles and tested them in those early years at our location on a leased line and at a large media/publishing company. This project has been written off.

Here’s a fun bit of history, on the tele, commenting on “browser wars”:

Technology Primer training

I am a hands-on geek who loves to tinker with technology, and if you want, I can take what I have learned and put it into a form that works for your business. My technology primer training programs are customized and delivered for the clients I work with.

Tech Evangelism

I have a passion for technology, especially good technology. If you think you have a product that has tremendous potential and traction in the market, and you need a product advocate and evangelist, talk to me. If I believe in your product, I can evangelize your product in the market through stakeholder presentations, seminars, conferences, product launches, media events, etc.

I love ALL kinds of technologies – not just computers and software, including:
