Work Experience

Team Lead

2024 - PRESENT
Vodafone UK
  • Got the title of team lead for my extensive knowledge about the different projects in Vodafone, with only five years of experience.
  • Took the initiative to use server-side rendering for Vodafone projects and Next.js, and it was a huge improvement for both quality and performance.
  • Created multiple npm libraries for different projects that helped separate the codebase into reusable components and applications so components could be used across other projects to boost development time.
  • Introduced Redux Toolkit and Redux Toolkit queries for creating progressive web applications that keep their state even after refreshing or reloading.
  • Took the initiative in using NestJS instead of Vanilla Node.js applications that drastically improved our web services' quality and performance.
  • Helped increase the performance of different Vodafone projects by implementing caching and reducing the number of needed communications between front and back end and databases.
  • Mentored five junior developers to use the best practices in developing React applications.
  • Created the structure for test-driven development to decrease the number of retests and ensure high code quality and performance.
Technologies: React, TypeScript, JavaScript, Next.js, MongoDB, NestJS, Webpack, Redux, Redux Thunk, TypeORM, PostgreSQL, REST, GitHub, Tailwind CSS, Material UI, Mongoose

React Developer

2023 - 2023
Copenhagen Economics A/S
  • Created an application from scratch with a very easy-to-read and maintain structure that someone who doesn't have a lot of experience in React can manage.
  • Added Redux for state management and persisted data on refresh to ensure employees didn't lose the data they entered.
  • Designed a beautiful UI with simple animations that give the application an aesthetic and modern feeling.
  • Integrated the company's Microsoft Azure Active Directory with the web application so the user can sign in using his credentials.
  • Created a mock development server for the REST APIs so they could try different testing scenarios without connecting to the actual API with accurate data.
Technologies: JavaScript, CSS, React, HTML, Material UI, JSX

Senior Full-stack Developer

2022 - 2023
IBM
  • Developed internal tools for logistics management in the company.

Full-stack Developer

2018 - 2019
