Hello, I'm Jarek.
$/~ Fullstack Developer &&
DevOps Enthusiast_
I specialize in creating scalable backend systems and intuitive web applications using modern technologies like Python, Django, and PostgreSQL. With a strong foundation in object-oriented programming and clean code principles, I focus on building maintainable solutions that stand the test of time. My approach combines technical expertise with continuous learning, always staying current with industry best practices and emerging technologies.
About Me
I am a developer from the Czech Republic, driven by a passion for transforming complex problems into elegant software solutions. My focus is on building robust and maintainable applications using Python, with practical experience in frameworks like Django and Flask. I am proficient in crafting user interfaces with HTML, CSS, and JavaScript, and I am committed to applying the principles of Object-Oriented Programming to write clean and scalable code. My choice of Omarchy Linux distribution as a daily driver reflects my philosophy: I thrive in efficient, terminal-centric environments that give me full control over my workflow.
