I had a great experience working on several interesting projects, which led to the creation of a boilerplate own template for quickly implementing already project with featuring modules for authentication, user management, files uploading, chats, and push-notifications, … etc.

Couple of projects:

• Mobile Fitness App with admin panel

The core feature of the app is paid courses, which include weight loss lessons and quizzes. For payment processing, Digistore24 was integrated, enabling users to purchase courses and access monthly subscriptions for exclusive recipes.

In the admin panel, the Edamam API was implemented to automatically calculate calories and other nutritional information for ingredients. The app also includes social features, allowing users to create posts and stories, like and comment, and engage in group chats, enhancing the community experience.

• Analytics social network platform

The project has a functional of social network: feed, chat, friends and feedbacks. But the main idea is to analyze statistics of users' social networks, then other company can compare these statistics to promote their products by influencer. So, from an interesting experience, I worked and researched with Facebook and Instagram API, to implement auth flow, and collect insights data for graphics.

• Social network with streaming functionality for artists

The project has a huge social network functional with many users roles and admin panel. The base idea is, artists, set their workdays schedule to make online public or private events with some price.

My non-standard and interesting experience was with difficult SQL queries to business logic for workdays in the calendar with repeat slots, FFmpeg lib for crop, create short videos. Also personal, group chats by socket.io, notification module by email, and push notification, which triggered with different events and time.

• Document sign platform

It’s similar to e-sign platforms, where users can upload documents and select signers. Also, there are chat, mail, push notifications
