“With great power comes great responsibility and when things are initiated, they open up the doors of curiosity.” Technology stands at the forefront of modern human lives and brings with it an immense amount of impact that matters. In my experience of working with companies like CERN, Intercom and SquadStack, I have learnt a great deal on building amazing user interfaces and in the process, fell in love with the craftsmanship. Leadership is not easy and in times when I got to lead teams and people, I gave them the best I had and grasped new teachings from them as we went, which further enhanced what I can give. Dynamism, passion and unwavering love for all things technology is what I bring to the table and I’d love to share my experiences with others while absorbing what they can give me so I can serve them better in the future.
