About

Greetings, my name is Suman Das Sarkar, a committed and enthusiastic Full Stack Developer well-versed in crafting web and mobile applications.

Hello! My name is Suman Das Sarkar, an enthusiastic Full Stack Developer known for my strong prowess in creating web and mobile applications. My specialty lies in React Native, and I enjoy tackling intricate issues and deploying inventive solutions. My professional journey kicked off at Nirva, where, as the sole frontend developer, I was responsible for creating the website and app from the ground up. My perseverance and commitment were key in enhancing the platform, effectively catering to the requirements of users and stakeholders. Recently, my endeavor has been Pulmo, an app innovatively tailored to assist individuals dealing with anxiety, mental health concerns, and COPD via efficient breathing exercises. This project is a testament to my dedication to craft significant solutions that enrich people's lives. I am always on the lookout for fresh projects which push my capabilities and enable me to actualize innovative concepts. Let's get in touch and pave the way for something extraordinary together!
