Portrait of Jaskirat Singh Oberoi

Engineer by passion, designer by choice.

I lead UX design and software engineering as a Director at Ares Labs. Before that I built design systems at Boomi and spent four years at Amazon, where I was Amazon India's first design technologist.

Freelance is where I started. I ran Hansei By Design for three years before big tech, and I still take on a few client projects each year through OpenRipples. The work is the same everywhere: take an idea from whiteboard to production without losing anything on the way.

Worked with Amazon, Amazon Business, Boomi, Ares Labs, OpenRipples, AT&T and Hanu Software, plus Noble Diagnostics and independent brands like Cove & Lane, Noukai Tokyo and Pragya Vijh.
