I know it is hard to find the right developer. They either turn out to be a lot more green than they lead on or they are brilliant but unreliable. Fortunately, I am both high-skilled and trustworthy. More than showing you a list of websites, I can let you know that: • I received 5 stars from 100% of my clients • I successfully completed all the projects I worked on • I have almost two thousand hours of work here • I have over 14 years of experience writing front-end applications • I scored in the top 3.7% of Upwork's Data Structure Test I have solid experience with full-stack development using JavaScript, including architecture, automated testing, and modern frameworks, libraries, and tools. Here are some of the projects I delivered: • A React web application for managing album releases, using Firebase and Stripe. It supports media uploads with progress status and has a customized audio web player. The application’s state is handled with Redux and Redux-Saga, tested with 100% code coverage. The user interface is responsive and was built with Material-UI. The application was implemented on a team of three engineers and is online since 2018. • A React web application for managing image assets for an online art gallery. It supports multiple image uploads, with progress status, and live editing. The application’s state is handled with Redux and Redux-Saga. The user interface is responsive and follows the material design guidelines. It is being used by hundreds of artists on a daily basis and is online since 2017. • A React web application for managing robotic wheelchairs. It is part of the Wheelie kit, known as the world's first face-controlled wheelchair. It uses Socket-IO for real-time communication. The application’s state is handled with Redux and Redux-Saga. The user interface is responsive and follows the material design guidelines. You can always expect responsibility, honesty, and high-quality work from me. You can also verify this from the testimonials below: • "Daniel's experience was invaluable in helping me with the planning stage of new development.
