Experience

Video Streaming Application

https://proquizlive.se/

I developed the over-the-top live streaming application with the live quiz feature. I worked on the streaming module to create this streaming service using AWS Media, AWS Lambda, and Node.js. I also developed the React Native app.

OTT Platform

https://gp.bioscopelive.com/

Biscopelive is one of the biggest OTT platforms in Bangladesh. I helped them build the initial front end using React and the back end using PHP. Also, I developed a few internal tools (a wrapper around FFmpeg) that help to encode and decode video for the client application.

Social Media Application

ICA is the largest grocery shop in Sweden. I help them to build internal social media applications. This application has features like feed, text, image, audio, and video content. I worked on the React Native application.

Service Node Application

Service Node helps service companies, equipment, and property owners work smarter and more efficiently with their service and maintenance work. I developed the mobile application using React Native. The mobile app has many advanced features like custom maps, real-time notifications, advanced animation, dynamic UI, and patch updates. Also, I worked on the web application built with React.

Ekkbaz

https://ekkbaz.com/

In most countries, the FMCG industry is still using analog systems for a product lifecycle, from manufacturing to the end user. The Ekkbaz startup wanted to digitalize this process. I developed the full mobile application from scratch and also implemented the robust, scalable Node.js microservices. This application is currently running in three countries with more than 1,000,000 consumers and 100,000 providers.

Dermly Application

This application is used to detect early-stage cancer by examining the red spot. I was responsible for designing a secure architecture for the application and developing a web app and a mobile app using React and React Native. This application has a feature like capturing microscopic images using a third-party device and advanced features such as real-time notifications. This project got the CE trademark.

Testing and Vaccination Application

Developed an application that helps Swedish citizens get different types of tests and get the vaccination, including the COVID-19 test and vaccination. My responsibility was to architect, CI/CD pipeline initiate, implement the build and daily backup system, and develop the front-end application using React.

State Management Library

In early AngularJS, we only had $scope and $rootScope. In each page change, the screen DOM was rendered, and we had a heavy UI state logic that was removed from each render. To prevent this, I implemented a state library that captures the last five-screen UI state logic.
