This is my technology and design consulting company; I am providing user-centric expertise in technology and design to companies such as Apple, Barclays, Virgin and Nomura. I can work as a UX Designer, helping companies to introduce a UX process, or working alongside other UX designers in an already implemented process. I can work as a UI Designer, with a keen interest in visual design and a love for creating simple and beautiful designs that work. I can also work as a Front-end Developer using the latest technologies such as HTML5, SCSS, and Javascript. I am logical with a sharp eye for detail. I believe my expertise in all three domains is beneficial to each other. Working as a designer and knowing some of the technological limitations will help speed up the process. Similarly, working as a developer and having a keen eye for details will ensure a pixel perfect implementation. In some of my experiences, I also managed multiple teams across departments such as software developers, UX/UI designers and QA.

Working on an e-learning platform for internal employees to learn about web accessibility.

Based on this research, I started working on the user flows, use cases, wireframes and continuously validate it by going back to the stakeholders, to avoid long stretches of design work. Once the design was approved, I started working on the front-end development using HTML5, SCSS and Javascript (React). Working alongside the back-end development team, we worked in an agile methodology to make sure problems were discovered quickly and dealt with efficiently
