About Me
I'm a Full-Stack Developer with over four years of experience building responsive websites and scalable web applications. I work primarily with Django, Wagtail CMS, and Ruby on Rails, creating clean, maintainable code and intuitive user experiences.
I enjoy developing both the front and back end of applications—from crafting accessible interfaces to designing efficient database models and RESTful APIs. I'm comfortable working independently or in agile teams, and I care deeply about performance, usability, and delivering real value through technology.
