Kelvin Ferreira SoaresFront End Developer
Senior Software Engineer with 7 years of experience in front-end development, including early-stage startups and Worldwide tech giants like Lenovo. My experience at Everly Health stands out as the most challenging and rewarding. I was responsible for improving the company's web portal that connected with hundreds of labs and delivered medical results to millions of US citizens during the COVID-19 pandemic. Some project highlights : 1. Rewrite the whole trio.dev website(PHP before), together with a junior front-end, into a static website using Gatsby and a CMS, aiming for performance and SEO. In the end, we were able to see the website being ranked 1st on search engines and an incredible rise in access and contacts from customer leads 2. Working at Layer, my team was responsible for building the alBaraka Bank App and I ended up being allocated to build the most important section of it, the payments page. This section was responsible for handling payments of many kinds from different account balances, including foreign currencies, so the complexity was extremely high, dealing with multiple data streams and countless business rules. The project was delivered on time to the client and is used by thousands of customers today. My strengths : A great sense of urgency when needed. An incredible capacity to work under pressure(deadlines, critical bugs, etc). The expertise and motivation in dealing with frontend high complexity problems. An extra willingness to provide great feedback on how to improve the company's processes or business The expertise to break frontend tasks down and create roadmaps to deliver results

Front-End Developer in a cooperative project between LSD (UFCG) and Lenovo Enterprise focused on Management as a Service (MaaS) concepts. The main goal of this project was to create a UI that reads and processes data in a source-agnostic manner, aggregating other services and tools such as ManageIQ and Lenovo Xclarity Client. Through this UI, named Portal, the Cloud Administrator can send commands to its infrastructure, whether it is physical or not, see plenty of useful information about the resources, and much more. This project relies on technologies such as Typescript, NodeJS, Angular 5, HTML5, and CSS3 and uses Agile Development as the methodology of choice.
