Since 2008

PhysicsHelp4u.com (2008)

I have always been enthusiastic about physics and mathematics. I developed my first website, physicshelp4u.com, in 2008 to offer free help on physics. The website was search engine optimized and it was a success when my site showed on the first page on Google Search for the keywords "physics help" and "free physics help". Although I own the domain now, the project is currently inactive.


Linux Server Administration (2008)

I got a bare metal server for hosting PhysicsHelp4u.com. It was 2008 when I started working on IT Infrastructure Administration, Security, and Application Development.


Linux Workstation (2008)

I built my first Linux workstation in 2008. It had a AMD Phenom II X6 1090T CPU, 16GB RAM, and a discrete graphics card connected to dual 22-inch 1080p monitors.


Personal Website (2010)

I created my personal website in July, 2010. The domain soumik.com was priced at $5000 and I could not afford it at that time. Finally, I switched it over to soumik.com in December, 2021.
