Hi there! πŸ‘‹ I'm Subhadeep Chowdhury

πŸš€ Software Engineer | Entrepreneur | Tech Enthusiast

I'm a passionate developer with expertise in building scalable applications across web, mobile, and IoT platforms. I love creating innovative solutions that solve real-world problems and exploring cutting-edge technologies.


πŸ”₯ Featured Projects

A feature-rich Flutter mobile application for note-taking with rich text formatting

Features:

  • Cross-platform: Works on both iOS and Android.
  • Secure Authentication: JWT-based login and registration.
  • Rich Text Editing: Create, format, and manage notes with ease.

How it Works:

  • The app provides a rich text editor for creating and formatting notes.
  • Users can organize, search, and manage notes efficiently through the UI.

Tech Stack: Flutter, Dart, JWT Authentication


Custom drone flight controller with advanced IMU and PID control systems

Features:

  • Advanced IMU Integration: Real-time sensor fusion for accurate flight.
  • Custom PID Control: Smooth and stable flight dynamics.
  • Wireless Communication: Low-latency command and telemetry.

How it Works:

  • The Arduino board interfaces with IMU sensors to gather real-time orientation data.
  • Custom PID algorithms process sensor data to stabilize and control the drone’s motors.
  • Commands can be sent wirelessly via WebSocket, and telemetry is streamed back to the controller.
  • The system ensures responsive and secure communication for reliable flight.

Tech Stack: Arduino, C++, WebSocket, IMU Sensors


πŸ“ Smart Blogz

Modern blog platform with intuitive content management

Features:

  • Dynamic Content: Create and manage blog posts easily.
  • Responsive UI: Seamless experience across devices.
  • RESTful APIs: Powerful endpoints for data access and manipulation.

How it Works:

  • Users register and log in to create, edit, and manage blog posts.
  • The frontend (Angular.js) interacts with the backend (NestJS) via RESTful APIs.
  • All blog content is dynamically rendered and managed through a user-friendly dashboard.
  • Backend handles authentication, data validation, and post management.

Tech Stack: Angular.js, NestJS, TypeScript


πŸ“© We-Share

We-Share is a social media backend built with TypeScript, Apollo GraphQL, and Neo4j. It provides core social networking features such as following/unfollowing users, Tweeting, and liking/unliking content.

Features:

  • Follow/Unfollow: Easily manage social connections between users.
  • Tweet: Users can post short messages.
  • Like/Unlike: Engage with posts by liking or unliking.

How it Works:

  • The backend exposes a GraphQL API, accessible at: https://we-share-api.onrender.com/graphql.
  • Data is modeled and stored in Neo4j, making relationship queries fast and flexible.
  • Operations such as following a user, posting a tweet, or liking content are handled through GraphQL mutations, while queries allow fetching user timelines, tweets, and relationship data.

Tech Stack: TypeScript, Apollo GraphQL, Neo4j
