Junior backend developer and ITAcademy student (Python Development).
I enjoy combining programming, mathematics and physics – from web apps to matrix operations and quantum simulations.

• Building Python CLI and web applications (Flask, JSON/CSV data, simple DB layers)
• Learning algorithms, data structures, OOP, Git/GitHub
• Exploring quantum computing basics and simulations in Python

Languages

• Python, C#

Backend & Web

• Flask, Jinja2 templating
• Basic REST patterns, simple auth/login flows
• Deployment on Render

Data & Math

• NumPy, Pandas, Matplotlib
• Linear algebra (matrices, vectors, transformations)
• Basics of SQL

Tools

• Git & GitHub
• Visual Studio Code, Visual Studio
• Windows, PowerShell, virtual environments

• Flask Web App (Login + Admin panel)
  Web app with user login, admin panel, template rendering and database access. Deployed on Render.
  Tech: Python, Flask, HTML/CSS, Jinja, Git/GitHub, Render

• Matrix (stipe_matrix)
  Educational library for basic and advanced matrix operations (addition, multiplication, transpose, determinants, scalar operations).
  Tech: Python, NumPy, Linear Algebra

• Quantum Sync Simulator
  Interactive simulator that visualizes the state of two qubits over time (Bloch spheres, measurement probabilities, entanglement strength, heatmaps).
  Tech: Python, NumPy, Matplotlib, basic quantum computing concepts

• Student System – Python CLI package
  Modular CLI application for managing students (OOP models, data layer, file I/O, reports). Packaged as an editable Python package with setup.py.
  Tech: Python, OOP, packaging, CLI design

(More projects available in the repositories section.)

Curious, self-driven learner who likes to understand how things work under the hood.
I enjoy:

• breaking problems into smaller pieces,
• writing clean, readable code,
• and connecting theory (math/physics) with practical software.
