CV

Fullstack Web Engineer | React, TypeScript, Python (Django)

I build responsive, high-performance web applications and solve complex backend challenges. I focus on delivering functional, scalable, and secure solutions tailored to specific business needs—from scratch to deployment.

My technical expertise includes:

  • Architecture & Networking: Designing robust RESTful APIs, implementing WebSockets for real-time data exchange, and building scalable system architectures.

  • Backend: Python, Django, database design and optimization (MongoDB, PostgreSQL).

  • Frontend: React, TypeScript, state management, and building intuitive user interfaces.

  • Core Engineering: My strong foundation in C++ (memory management, multi-threading, STL) gives me a deeper understanding of under-the-hood web processes, ensuring my code is highly optimized and efficient.

Whether you need to build a complex admin panel, integrate third-party APIs, develop a Telegram bot, or fix critical bugs in an existing web app, I write clean, maintainable code and deliver results quickly. Ready to jump into your project.

    Custom Python Web Framework (HTTP/Routing Core)

    Python
    Custom Python Web Framework (HTTP/Routing Core) — example of freelancer's portfolio work in category Python
    Developed a custom, lightweight web framework and HTTP server in pure Python without relying on external libraries like Django or FastAPI. Designed to provide deep, low-level control over client-server architecture.

    Core Features:
    TCP/HTTP Core: Raw socket handling, HTTP request parsing, and response generation from scratch.
    … Custom Routing: Modular routing system (similar to Django's urls.py) mapping endpoints to specific handlers.
    Static & Templates: HTML page rendering and secure static file processing.
    JSON DBMS: Built-in lightweight NoSQL data management system based on JSON for rapid data storage and retrieval.

    This project demonstrates a profound understanding of under-the-hood web mechanics, allowing me to write highly optimized backends and tackle complex, non-standard architectural challenges.

    Universal Web Scraper CLI Tool (Python, OOP)

    Data Parsing
    Universal Web Scraper CLI Tool (Python, OOP) — example of freelancer's portfolio work in category Data Parsing
    Developed a flexible CLI utility for web data scraping. Instead of hardcoding scripts for specific sites, the tool accepts target URLs and selectors (HTML tags and classes) directly via an interactive terminal, dynamically extracting content.

    Technical Details:
    Architecture: Strict OOP approach with separated modules for scraping logic, data exporting, and CLI.
    … Interface: Interactive terminal built with the rich library, featuring colored logging, progress bars, and live table previews.
    Export: Supports saving scraped data into machine-readable .csv format (via pandas) or formatted ASCII tables in .txt files.
    Reliability: Includes network exception handling and input validation.
