I'm a full-stack developer with 4 years of experience, primarily focused on building fast, scalable, and maintainable web applications. My core technologies are React (with TypeScript or JavaScript) and Django (Python) on the backend, but I'm also highly comfortable working with Vue 2, Nuxt.js, and advanced bot automation using Telethon for Telegram.

Frontend Skills
I build modern, responsive user interfaces using React (including hooks, Redux, context API), as well as Vue.js 2 / Nuxt.js for SSR or SEO-friendly projects. I'm confident with TypeScript, modular architecture, component-based design, and UI libraries like Ant Design, Vuetify, or TailwindCSS. I aim for clean, well-documented code and prioritize usability, accessibility, and performance.

Backend & API Development
I use Django / Django REST Framework to build secure, robust APIs, admin dashboards, and database-backed applications. I’m comfortable designing database schemas (PostgreSQL, MySQL), managing auth, and handling background jobs (Celery, Redis). I’ve also worked with Supabase and Firebase for rapid MVPs.

Telegram Bots & Automation
I have deep experience with Telegram bots, especially using Telethon for advanced use cases like:
  • Group/channel monitoring
  • Message parsing and media handling
  • Custom user interaction flows
  • Integration with external APIs (for alerts, databases, or content generation)
I’ve built bots that manage thousands of users and interact asynchronously across multiple groups and platforms.

Other Tools and Technologies
  • Java (core + 3D graphics – experience with JavaFX and 3D modeling/rendering engines)
  • WebSockets, GraphQL, RESTful APIs
  • Deployment with Docker, NGINX, Gunicorn, and cloud providers like DigitalOcean or Vercel
  • CI/CD setup using GitHub Actions or GitLab pipelines
Working Style & Collaboration
I'm independent and proactive but communicate clearly and regularly — especially in async or distributed teams. I’m comfortable taking ownership of features, planning architecture, and coordinating with designers or stakeholders. I avoid overengineering and focus on shipping useful, stable features fast.
Whether you're looking to build a clean MVP, integrate with Telegram, or develop a full-stack web app — I’d be happy to help. I'm passionate about building tools that actually make people's lives easier, and I take pride in delivering solid, reliable results.
