I have created my developer portfolio using HTML, CSS, and Vanilla JavaScript. I have implemented dark/light theme toggle, scroll animation, skill bars, project cards with filters, pop-up modals, and contact form with validation. The most challenging aspects of this project were to achieve all theme persistence, animation, and interaction effects without using any external libraries or frameworks. I am particularly proud of the clean design and rich micro-interactions which were achieved without any third-party libraries. You can view the implementation details of this project by interacting with a dark/light theme switcher, filtering the projects, checking out the contact form validation, and seeing how the responsive mobile menu works :)
