Project History
Herbtech
Herbtech is a cannabis technology company providing self-service kiosk solutions to medical and recreational dispensaries, where the kiosk application is written Flutter. The project was built with Express.js on the back end, PostgreSQL as the database, and Angular as the front-end framework. I worked on the web application and optimized the kiosk application.
Knights Bridge
Developed a full-stack application made with microservices architecture. I was a team lead on this project. The application had 15+ modules, including user management, coin management, fiat deposits, and withdrawals. There was an unexpected requirement from the client to add a feature to impersonate an admin and because of my coding pattern and intuitive sense, this feature was developed and implemented in just two days rather than a complete sprint.
Viteq
Viteq is an automatic medicine ordering system, where the users just go to the doctor, and Viteq taking care of the rest and the tech stack for this application I used Angular, Flutter, NestJS, and MongoDB. I worked on both the front and back-end parts of the application with a team of two people.
Fortune Magic Chocolate Minting Daap
Fortune Magic Chocolate is a French-based brand. As a marketing strategy, I built a system where users could scan a QR code from the chocolate box and receive an NFT in their crypto wallet based on the luck factor. The system had an administrative portal and a smart NFT-generation strategy, saving a lot of Lambda computing power.
STEM Profile Application
A Flutter-based web application where users can have different personas of their profile for multiple needs, like as a teacher, scientist, etc. The application has a chat feature for communicating with other people and can share videos and images.
Language Learning Application
A Flutter-based application that enables teachers and students to communicate with each other. The app has a pretty awesome feature for translation during messaging in groups or one-on-one interactions.
The app was built with a matrix ecosystem. Pangea chat has its own home server.
