My profile:

Senior web/app developer,
who does full stack and is also well-versed in the frontend field.
  • I know current frameworks (React Native, Angular, Vue) and libraries (React) well.
  • My focus is on React / React Native and its ecosystem (e.g. Redux, GraphQL, webpack).
  • Agile software development (z.B. Kanban and Scrum) is more than familiar to me.
  • I communicate with all participants (e.g. PM, backend, UI/UX-design, ops, sysadmin) at eye level.
  • build tools and versioning system go without saying.
  • ECMAScript 20XX/TypeScript and Node.js I know well.

Which value can I offer you moreover:

  • I bring my 12 years of expert knowledge and practical work experience to the table.
  • I always work for one project at a time only, cause multi-tasking doesn't work and context switches are expensive.
  • I integrate myself seamlessly within agile teams and participate actively within the introduction of agile software development (e.g. Scrum/Kanban), if desired.
  • I value clean, legible and simple code. Tests and documentation as well as code reviews are for sure.
  • I know all practices of „eXtreme Programming“ and use many of them (e.g. pair programming, coding standards, code review, continuous integration, continuous delivery, planning, unit tests, integration testing). On demand I'm happy to implant them within the team culture.
  • I am decidedly a team player, because I'm a former long-term employee who also worked with IT freelancers. I know the possible friction and requirements for them.
  • I have a professional standard for leaving qualitative, comprehensible and maintainable code behind. Therefore I actively pass my knowledge to your team for the time after my assignment.
