Roman Z.

As a freelance developer, I specialize in creating web and mobile applications with a fullstack approach, using React and Next.js for the frontend, Node.js and NestJS for the backend, and React Native with Expo for mobile environments. My priority is to adapt the technology to the needs of each project, seeking a balance between performance, scalability, and development speed. Thanks to my experience in agile methodologies, I offer maintainable and easily evolving solutions over time, with the goal of creating products that grow sustainably and bring true value to the business.

As a technical lead, I took on the role of directing a frontend development team, ensuring the quality of the delivered code. My responsibilities included preparing technical specifications for user stories, providing support in resolving technical challenges, optimizing team workflows to achieve sprint goals, conducting code reviews through pull requests, and delivering training sessions to enhance team skills. Additionally, I participated as a fullstack developer in another project, contributing to both frontend development and backend solution implementation.

My role in this company was to develop and maintain aggregator portals for different verticals, being part of a team with a development culture based on Extreme Programming methodologies, such as TDD, refactoring, and pair programming as its main pillars.
