02 / ABOUT

About

Renvoxit creates modern responsive websites, web systems with backend functionality, Telegram bots, API integrations, databases, automation, and custom digital solutions for practical tasks.

Each project is built around what people need to accomplish: clear interfaces, useful functionality, reliable data handling, and maintainable technical foundations. Python backend development, deployment, and security-oriented engineering support the work without limiting Renvoxit to backend-only projects.

Responsive Interfaces

Clear, maintainable interfaces built for real screens and real use.

Backend Functionality

Useful flows supported by Python, APIs, and reliable data handling.

Databases & Automation

Structured information and workflows that keep practical systems moving.

Security-Oriented Engineering

Validation, safe data handling, and maintainable technical boundaries.

03 / TECH STACK

Technical Foundation

Built Beyond the Interface

When a project needs more than a visual page, Renvoxit can connect the interface to Python backend functionality, APIs, databases, authentication, automated workflows, and Docker-based deployment. Security-oriented thinking supports validation, password handling, sessions, rate limits, and clear service boundaries.

05 / SELECTED PROJECTS

Projects

PROJECT 01

Status: Portfolio project

Online Restaurant

Online ordering system that lets customers create an account, browse a restaurant menu, manage a cart, place orders, and review their order history. Administrators can manage dishes and incoming orders through a dedicated panel.

The application includes database-backed accounts and order data, PostgreSQL and local SQLite support, Docker configuration, CSRF protection, hardened sessions, and rate limiting.

Stack: Python 3.11 • Flask • PostgreSQL • SQLite • SQLAlchemy • Flask-Login • Flask-WTF • Bootstrap • Docker

GitHub

PROJECT 02

Status: School competition project

BuildSmart

German-language civic feedback platform where residents can report city problems and share improvement ideas. Users can publish a post with an address, description, and optional image, then vote and discuss proposals through comments.

The full-stack project includes API-connected frontend interactions, SQLite persistence, file uploads, post and comment deletion through a local client-token mechanism, and separate categories for Vorschläge and Anmerkungen.

Stack: Python • Flask • SQLite • JavaScript • HTML • CSS

Built as a school competition project with backend routes, persistence, frontend interaction, voting, comments, file uploads, and product-oriented thinking.

GitHub  •  Live Demo

PROJECT 03

Status: Telegram bot project

Telegram Movie Collection Bot

Telegram bot that keeps a personal movie collection accessible inside a chat. Users can browse film details, search by title, filter by genre, add films, edit descriptions, update ratings, and remove records.

The implementation uses command flows and inline keyboards for navigation, FSM-based create, edit, rate, and delete actions, lightweight JSON storage, and unit tests for storage helpers and handlers.

Stack: Python 3.11+ • aiogram • Pydantic • unittest • JSON

GitHub

PROJECT 04

Status: Security project

Password Strength & Breach Checker

Web tool that helps users evaluate password strength and check whether a password appears in known breach data through the Have I Been Pwned API.

Passwords are hashed locally before the breach lookup, so the raw password is not sent to the external service. The project combines a practical user check with safer data handling.

Stack: Python • Flask • Requests • HTML • CSS • Have I Been Pwned API

GitHub

PROJECT 05

Status: Database integration project

Shoe Store

Small online storefront where users can browse shoes and submit an order with their contact details. Product and order flows are connected to a PostgreSQL database through Flask and SQLAlchemy.

The customer journey is organized into a clear home page, product catalog, and order form.

Stack: Python 3.13 • Flask • PostgreSQL • SQLAlchemy • HTML • CSS
