Freelance Frontend Consultant

]init[ AG für digitale Kommunikation

As a consultant at ]init[, I had the opportunity to work on a government contract where I played a key role in building tools to automate a previously manual process. My focus was on building a complex multi-step form using React and TypeScript.

My responsibilities included sketching out the architecture of the application and coordinating the integration of the React application into a Drupal page. Additionally, I ensured that all developers working on different parts of the project were able to communicate effectively and align their efforts towards a common goal.

Overall, I leveraged my expertise in React and TypeScript to deliver a high-quality application that streamlined the administrative process.

Freelance Frontend Consultant

Mister Spex

As a Principal Frontend Consultant at Mister Spex, I had the privilege to work on three significant projects that contributed significantly to the company's success.

Firstly, I was part of the team that rebuilt the company's webshop, focusing specifically on improving the performance of the product detail page. Using my expertise in Next.js, React, and TypeScript, I implemented performance optimizations that significantly reduced the time to first paint and minimized layout shift. In addition to my development responsibilities, I also mentored junior developers and ensured that they were confident contributors to the project.

Secondly, I contributed to the development of the component pattern library for the company. Working closely with the design team, we delivered reusable components that were utilized in various projects throughout the company, ultimately resulting in improved development efficiency and code consistency.

Finally, I was part of the team that developed new components for the Contentful CMS the company was using. Our focus was on the optimal utilization of the purchased Contentful plan, resulting in a reduced number of components that enabled us to automate the creation of different pages. Our efforts reduced the time required for content creators to perform certain tasks from two weeks to one day.

Overall, my contributions at Mister Spex showcased my expertise in frontend development, mentoring, and project management, resulting in improved performance, efficient development practices, and streamlined workflows.
