Python developer focused on building practical desktop tools for automation, data processing and security.

I specialize in creating real-world, production-ready desktop applications using Python. My projects focus on solving actual business problems such as:

• data cleaning & transformation
• automation & lead generation
• file management & backups
• security & encryption
• API testing and integrations

I prefer building useful tools over tutorial projects — everything in my portfolio is designed to be usable in real scenarios.

Languages & Core:

• Python

GUI / Desktop:

• PyQt6 / PySide6
• Tkinter / CustomTkinter

Data & Processing:

• Pandas
• CSV / Excel handling
• Data cleaning & normalization

Databases & Storage:

• SQLite
• JSON

Security:

• Fernet encryption
• SHA256 hashing
• bcrypt
• PBKDF2

Automation & Integrations:

• SMTP (email automation)
• Playwright (web scraping)
• BeautifulSoup / Requests
• Tesseract OCR

Other:

• PyInstaller (building .exe apps)
• Threading / async processing
• Modular architecture (core/services/ui)

Encrypted password manager with generator and strength checker. Focus: secure storage, UX

• Building useful tools, not demos
• Solving real business problems
• Writing clean, modular code
• Designing intuitive desktop interfaces
• Working with data and automation

I am currently expanding into:

• FastAPI (backend development)
• API integrations and services
• Deploying applications (cloud / web)

Looking to work as a Python Developer (Automation / Data / Backend) where I can build tools that actually solve problems.

Most of my projects started as tools I actually needed — then turned into full applications, used by several entities.
