This is a full page just about me.


Who I Am

My name is Vahid Hallaji. I am a software engineer based in Melbourne, Australia who develops web and mobile stacks. I have studied Software Engineering and Master of Information Technology at Azad University and Monash University respectively. Back in 2007, I co-founded Narmand and got a valuable experience through developing large-scale web applications for Tabriz University of Medical Sciences. Besides, I worked in a team to deliver dozens of websites and helped a few private businesses. I also attended meetups, mentored voluntarily at startup weekends, and shared my personal experience with local communities.

What I Do

I make software. If you have a project or an idea that requires co-thinking or some creative injections, then that is where you could count on me. I strive to create elegant looking apps and websites while making them simple for the end-users. There is something very satisfying about creating things. I focus on what excites me and do so with some style and passion. I am always active behind the scene of software products and enjoy programming. Currently, I am working on a brand new backend infrastructure of the employee engagement and performance management solutions at CultureAmp to amplify the experience and the impact of 100 million people at work ;⏎
