The main private project that I’m working with is called VikingsToolbox and consists of a system composed of:
A paid app that has the main functionality of changing some files in user games folders for better performance. It has integration with Shizuku to get access to Android/data folder and the user can buy his access automatically through the app with integration for payments with PIX (brazilian payment method) and credit cards using Stripe.
Built with: Kotlin, Jetpack Compose, Ktor, coil, Accompanist Pager
The backend manages the users, serve the zip files to the client and integrates with all necessary APIs and to the WhatsApp BOT. I developed automatic payments integrations with MercadoPago, Efí and Stripe. Also created a re-seller system where interested individuals can register to sell our product under coupons and earn commission.
Built with: Python, Flask, Flask-Login, SQLAlchemy, requests, MySQL
This BOT is used to send notification to users with his access information on success payments and also when a payment is not completed to ask if he had any problem during the proccess. For admins it offers a lot of commands to control users and payments. Also used for automating marketing messages in WhatsApp groups.
Built with: NodeJS, express, whatsapp-web.js
I’m the creator and only maintainer of all these projects.
