I’m Ervin, mostly using handle @ervinismu on the internet, live in Indonesia. I’m an entrepreneur and software developer, started all the software related things in 2013 when I worked as a computer technician for computer repair and software installation.
A few years after that, I started my professional career as a software developer focusing on web stuff and spent a lot of time writing Ruby stuff on the web, and later writing some Go & JS. Since then, I consider myself a Ruby Developer. See more at my work for a more detailed work history.

Why using flower profile picture?

I often use flowers as my profile picture on the internet. Flowers are beautiful when they bloom, but they don’t last forever. Flowers always remind me of my world/life. Sometimes they look beautiful, but they don’t last forever. Flowers always remind me to prepare for the next life when I’m no longer in this world.
May Allah always guide us on the right path, AAMIIN
