My Expertise

I'm a backend developer specializing in building scalable, real-time systems with modern technologies. My core tech stack includes Python, FastAPI, and Django for robust API development, alongside PostgreSQL and MySQL for efficient data management. I leverage Redis for caching, message brokering, and advanced rate limiting to optimize backend performance. For asynchronous processing and background tasks, I integrate Celery with Redis, ensuring non-blocking operations and reliable delivery. My experience also includes implementing JWT-based authentication, role-based access control, and secure API workflows. I am comfortable with tools like VS Code, Git, and GitHub, and have developed solutions ranging from chat systems and freelance marketplaces to customer support platforms.

Featured Projects

Chat Application Backend

  • Featured Skills :
    FastAPI, PostreSQL, Redis, Celery, Database Partitioning
    Rate Limiting & Throttling, Asynchronous Task Queues
  • Developed a scalable, real-time chat backend enabling one-to-one and group messaging with persistence and offline message delivery using FastAPI and PostgreSQL.
  • Implemented sliding window rate limiting using Redis sorted sets to prevent excessive requests per user.
  • Utilized Redis as both Cache and Message Broker for real-time user tracking and active participant management.
  • Integrated Celery asynchronous task queues with Redis as Message Broker for handling non-blocking background processes such as sending throttled email notification to users.
  • Enhanced database efficiency by implementing hash-based partitioning of PostgreSQL message tables and configuring connection pooling to minimize query latency and balance load across concurrent chat operations.
  • Secured authentication using JWT-based access control ensuring efficient and safe user verification.


    • Chat Application Database Schema

    Freelance Marketplace

    • Featured Skills : Python, Django, PostgreSQL, Tailwind CSS
  • Developed a full-featured freelance job marketplace enabling seamless user registration, profile management, and job posting workflows using Django and PostgreSQL.
  • Integrated cloud-based data storage with Cloudinary for handling images, text, and media files in markdown-compatible format, ensuring efficient and scalable asset management.
  • Implemented secure role-based access control (RBAC) using Django middleware and built-in authentication system to differentiate permissions between clients and freelancers.
  • Optimized PostgreSQL database performance by indexing frequently queried fields and minimizing redundant joins for faster page load times.

    Other Projects

    Customer Support Application

    • Featured Skills : Flutter, Dart, BLoC, Firebase
  • Built a Flutter application with Dart for posting, tracking, and resolving user issues efficiently.
  • Integrated Firebase Authentication and Cloud Firestore to enable role-based user management.
  • Implemented state management with BLoC to streamline data flow and enhance application performance.
  • Developed interactive features such as like and favorite options to deliver an engaging user experience.


    • Tasks API

    • Featured Skills : RabbitMQ, FastAPI, PostgreSQL, Celery
  • Built a tasks API using FastAPI to manage projects and member-assigned tasks with creation, reassignment, and status tracking workflows.
  • Implemented asynchronous email notifications via Celery workers with RabbitMQ as the message broker for background task execution.
  • Used PostgreSQL with SQL schemas for users, projects, and tasks, running on a Python 3.13.5 codebase.
  • Secured endpoints with JWT-based authentication and environment-driven configuration for broker, database, and mail services.
