#About Me

I am a software developer with a passion for problem-solving. My expertise lies in Python, Django, and Go, and I have a strong foundation in designing RESTful APIs, writing comprehensive tests (unit, integration, and BDD), debugging software, and monitoring applications. I thrive on finding simple, elegant solutions to complex problems, and I am always eager to learn more about software architecture, design patterns, and improving both my coding and soft skills.
