About me

I am a Senior Frontend Developer with 9+ years of experience building fast, accessible, and scalable UI. Now what is UI? UI stands for User Interface that helps user to interact with the system. Let's take an example: You bought a TV, Now how to interact with the TV? You need some kind of interface that helps you to use or interact with the TV. That's why TV comes with Remote. This Remote has many buttons in it to interact with the TV such as up/down volume button, change channel button, open menu button, etc. So, here Remote act as user interface to interact with tv. Just like this I build UI that helps user to easily interact with the system. I have an experience in translating product and UX requirements into performant, well-tested, SEO- and accessibility-compliant interfaces, with solid working knowledge of browser and network fundamentals (HTTP/S, CORS, caching, CDNs). Comfortable collaborating closely with engineers and product managers in autonomous, cross-functional teams, with a growth mindset and an experimental, test-and-learn approach to shipping new features.
