Engineering Projects

1. Subscription & Expense Tracker PWA [ Live Project ↗ ] | Python 3.12, Django, PostgreSQL, Celery/Cron, Telegram Bot API, PWA

   • Architected and deployed a production-ready Progressive Web Application (PWA) for managing recurring subscriptions and personal expense tracking.
   • Implemented dynamic renewal date calculations, recurring cost projections, interactive category filters, and expense analytics dashboards.
   • Engineered an automated background notification pipeline with Telegram Bot API integration for billing alerts and transaction logging.
   • Configured user authentication workflows, password resets via SMTP, and optimized database queries using Django ORM select_related/prefetch_related.

2. Students Community Forum Single-Page Application | React 18, Vite, React Router, JavaScript (ES6+), REST API, CSS3

   • Developed an adaptive client-side SPA forum featuring modular component architecture, responsive layout, dynamic discussion threads, and theme toggling.
   • Integrated asynchronous REST API client communication (Fetch/Axios), handling HTTP status codes, loading states, and form validations.
   • Configured client-side navigation with React Router and state management workflows for dynamic discussion threads.

3. Game Telemetry & Ranking REST API | FastAPI, Asyncio, Pydantic v2, PostgreSQL, Pytest, Uvicorn

   • Engineered a high-performance asynchronous REST API backend to collect real-time gameplay session metrics and telemetry data.
   • Implemented strict input validation and data serialization models using Pydantic, providing automated interactive OpenAPI (Swagger) documentation.
   • Built leaderboard ranking algorithms and covered critical CRUD endpoints with automated test suites using Pytest.

4. Enterprise Service CRM & Data Snapshot Engine | PHP 8, MySQL (3NF), Data Snapshots, ACID Transactions, Bootstrap 5

   • Architected and normalized a relational database schema up to the 3rd Normal Form (3NF) for computer hardware repair management and technician dispatching.
   • Implemented an immutable Data Snapshot pattern to preserve historic billing records, preventing data corruption across historical invoices and repair certificates.
   • Developed an administrative dashboard with transactional status updates, role-based access control, and diagnostic reporting.

5. 2D Arcade & Action Physics Game Engines (Pirat Shooter & Ping Pong) | Python, Pygame, OOP Architecture, State Machines, Physics Engine

   • Developed modular 2D arcade games in Python utilizing strict Object-Oriented Programming (OOP) paradigms and custom state machines.
   • Built optimized main game loops, delta-time sprite animation systems, keyboard input handlers, gravity/projectile physics, and sound integration.
