Quick introduction

I've been hand-crafting end-to-end, responsive applications, both simple and complex, for mobile and web, using React Js, React Native, and Node Js for more than three years now.

Among UI libraries, I prefer using Material UI 5 (Mui5), React Native Elements, Bootstrap, and ReactStrap. I am also good with AWS, Firebase, Twilio, Facebook, and Google Apis.

Backend is an Express Server using Node Js, Mysql using Sequelize library, and secure JWT token based authentication with multiple user roles.

About me

Indian national, age 50, currently based in Kolkata, India.

I started off with JAVA and spent over 10 years with it before switching to Php, Codeigniter, Jquery, Bootstrap, Apache, and Mysql.

I've been making web and mobile applications with react js, react native, and node js, for three(3) years now and consider myself good with these tools.

Familiar with functional components, hooks, redux, context api, typescript and more.

What I can do

Fully customized, dynamic, end-to-end, web and mobile application development with authentication and role based access control and permissions.

Integrated with the best and latest open source technologies such as Google, Firebase, Twilio, AWS, Facebook and more.

Can do both front-end UI/UX as well as backend. Can make admin dashboards implementing custom designed workflows with a buttery smooth UI experience.

If you have a web or mobile specification - I'll bring it to life!
