Experience

Web App for Hovertise

The Hovetise portal is a management portal for Boxeyi that manages the company's operations. It involves communicating with the IoT, moving screens, playing different images or videos depending on advertisement contracts, and managing drivers. It also provides detailed reports on customer numbers by analyzing the route and location advertisement data from IoT devices. I developed the Python Django web app from scratch, a management dashboard, a dashboard for drivers, a sales dashboard, a customer dashboard, and a real-time location of IoT devices. I also saved and compressed the location data, drew heatmaps and routes, sent email reports, etc. I used Python Django for the back end, Bootstrap, JavaScript, and CSS for the front end, PostgreSQL for a database, the Python machine learning algorithm for data compression, Gunicorn, Nginx, and Daphne for the production environment setup, and Django Channels and WebSockets for real-time communication with IoT devices.

Web App for Thinkgroupy

This platform helps freelancers get projects, and organizations get skillful developers from all around the globe. Clients can communicate with developers using real-time messaging rooms or have voice and video calls. They can also use the web app to pay developers. The app has a lot of different features. I implemented the real-time chat rooms using Django Channels, contributed to developing the platform, and deployed the real-time Django web app using Daphne, Gunicorn, Nginx, PostgreSQL, Redis, etc.

Web App PyNetworking

This Python Django web app helps people earn by making networks. Any user can build a team for themselves by referring others, and their team decides on the standard for their earnings. The entire tree network gets benefits from each newly registered user. After the membership expires, this process repeats, and users can earn a large amount of money. Also, the platform's money is converted to cryptocurrency, so each user could also benefit from using blockchain technology. I used Python Django for the back end, JavaScript for graphs, Bootstrap for the front end, CSS for making tweaks in the front end, and Nginx, Gunicorn, and PostgreSQL for the production setup.

Smart Tourism Web App

A Python Django-based web app that provides smart solutions for people to visit tourist destinations. Users can explore tourist places, get to know about experiences of people visited in the past, book a trip, book a car, hire a tour guide, all solutions under one platform of the Smart Tourism web app.
