About Mariusz Rajczakowski:

Experienced front-end developer with a proven track record across various industries, from e-learning to telecommunications. Skilled in designing, developing, and testing responsive web applications. A strong professional in JavaScript frameworks engineering, holding a Bachelor of Science (BSc) with a focus on best web practices and user experience.

Experience

With over 10 years of experience as a Web Developer, I have had the opportunity to work on a diverse range of projects that have sharpened my expertise in delivering high-quality user experiences and writing clean, efficient code. Over the past five years, I have focused on projects that primarily utilized React as the main library. For the last two years, I have been developing and maintaining React applications at Access Fintech, working extensively with complex data structures and flows. 

Throughout my career, I have been actively involved in the entire product development lifecycle, including requirements gathering, planning, scoping, documentation, and Agile/Scrum-driven development within teams of various sizes. As mentioned above over the past 5 years, my primary focus has been on developing single-page applications using JavaScript, React, ES6, Redux, and GraphQL, with interface styling achieved through styled-components, LESS, and a range of UI design systems. I am a strong advocate for robust testing strategies and practices, utilizing tools such as Jest, Vitest, React Testing Library (RTL), and end-to-end frameworks like Cypress and Playwright.
