As the front-end developer on this project, I was responsible for building the entire user interface with precision and performance in mind. I initially converted Illustrator-based designs into semantic HTML and then rebuilt the final UI using Vue.js and Tailwind CSS, ensuring full responsiveness across all screen sizes. The implementation perfectly matched the original Figma design, maintaining pixel-perfect accuracy while optimizing for performance and accessibility.

Develop Feasibility Simulation Web App

My team and I asked Mortuza to design a simple web app to evaluate the feasibility of projects and the related costs. He provided a precise and well-developed final product, with a clean and user-friendly interface, and which contained every feature we asked for. The app was delivered on time, and he was professional, quick to respond and collaborative throughout the whole creation process. We most definitely look forward to working with him again if we ever have the chance!
