Frontend Developer, Betterhalf.ai

Apart from mountains, I find peace in making PIXEL
perfect UI with REACT

About me

It all started with my friend calling me, and saying he has learnt a beautiful framework called FLUTTER. Back then I was at my first year in my undergraduate degree, and I had no idea what on earth he was talking about.

Fast forward to today, I am building websites, Mobile Application for my company, I have betted my life on this single framework called REACT. I never knew I would love building UI/UX so much until I started doing it.

I graduated in 2023, in Computer Science and currently I am working as a Frontend Developer at Betterhalf.ai, where primarily I am working as a React Native Developer. I have been responsible in launching couple of their apps, and websites to production each of them having some beautiful UI elements which we have built frame scratch
