Backend Frameworks     Python     Django     FastAPI     DRF  
Databases     PostgreSQL     MongoDB     MySQL  
DevOps & Tools     Docker     GitHub Actions     Git     Postman  

Key Competencies

  • Backend Architecture & REST API Design
  • Database Modeling & Query Optimization
  • Containerization (Docker) and CI/CD implementation
  • Clean Code & Software Design Principles

💡 My Development Philosophy

def backend_development_approach():
    """
    Principles guiding my work on every project
    """
    return {
        "architecture": "Design for scalability and clear separation of concerns",
        "code_quality": "Clean, highly readable, and well-documented Python code",
        "data_integrity": "Prioritizing strong database schemas and optimized queries",
        "testing": "Writing unit and integration tests for reliable deployment",
        "automation": "Leveraging CI/CD and Docker for consistent deployment"
    }

🚀 Featured Projects

Framework Database Auth

A secure and scalable RESTful API powering a complete e-commerce platform.

  • Core Feature Set: Implemented endpoints for product catalog management, cart operations, order processing, and payment gateway integration (mocked/placeholder).
  • Security & Permissions: Developed role-based permissions (Customer/Admin) and secured access using JWT authentication within Django REST Framework.
  • Database Design: Designed normalized database schemas using PostgreSQL to handle complex relationships between products, inventory, users, and orders efficiently.
  • Scalability: Leveraged DRF serializers and viewsets for rapid, standardized API development and easy maintenance.

Tech Stack: Django • DRF • PostgreSQL • JWT • Unit Testing 💻 View Code


Framework Roles ORM

A comprehensive, Django-based backend for an educational learning management system (LMS).

  • User Management: Implemented custom user models with distinct roles for Students and Instructors, controlling access to course creation and enrollment features.
  • Content API: Developed APIs for managing courses, modules, lessons, and tracking student progress and completion status.
  • Data Integrity: Ensured transactional integrity using Django's powerful ORM for reliable creation and modification of learning resources.
  • Deployment Ready: Architected with clear separation of concerns, utilizing Django's built-in security features for a robust backend.

Tech Stack: Django • Django ORM • PostgreSQL • Custom User Models • Permissions * Docker * Redis * celery * CI/CD 💻 View Code


Framework Performance NoSQL

A high-speed, asynchronous backend for a modern social media application.

  • Asynchronous Processing: Built using FastAPI to handle high volumes of concurrent requests (posts, likes, comments) using Python's async/await.
  • Data Modeling: Utilized MongoDB (or a similar NoSQL solution) for flexible, schema-less storage of user feeds and post data, ideal for rapid content changes.
  • User Interaction: Implemented core social endpoints, including user feeds, following/unfollowing, and instant notification capabilities.
  • Documentation: Provided automatic, interactive API documentation (Swagger/ReDoc) for easy testing and frontend integration.

Tech Stack: FastAPI • Python • Pydantic • MongoDB • Asynchronous Programming 💻 View Code

🌱 Interests & Engagement

Beyond the keyboard, I am passionate about:

  • Research & Learning: Actively studying new architectural patterns and frameworks (e.g., event-driven systems).
  • Problem-Solving: Applying creative thinking to simplify complex technical challenges.
  • Creative Pursuits: Enjoying music and cooking as a way to engage my creative mind.

📫 Let's Connect!

I am open to:

  • 💼 New opportunities in Backend Development.
  • 🤝 Collaborations on interesting Python/Django/FastAPI projects.
  • 💬 Networking with other developers and engineers.
