We are looking for a Junior Frontend Developer to help us gradually modernize and unify the frontend of our web application. This role is ideal for a student or junior developer looking to gain real-world experience while working on meaningful, production-level projects.

What you’ll be working on

• Refactoring existing frontend code (legacy/custom CSS) into Tailwind CSS
• Unifying styles across multiple pages to achieve a consistent design system
• Improving code readability, structure, and maintainability
• Collaborating on small, clearly defined tasks within a larger refactoring effort

Requirements

Basic to intermediate knowledge of:

• HTML
• CSS
• SASS/SCSS
• Tailwind CSS
• Ability to understand and refactor existing code (not just build from scratch)
• Attention to detail (pixel-perfect mindset is a plus)
• Ability to estimate tasks and propose pricing (project-based work)

Nice to have (not required)

• Experience with template languages (e.g., Jinja or similar)
• Basic JavaScript knowledge
• Familiarity with jQuery and/or React is a plus
• Understanding of component-based UI thinking

How we work

• Work is project-based (freelance collaboration, not full-time)

• Flexible workload — ideal to combine with studies

• Tasks are defined in advance — you provide:

  • Time estimate

  • Price for delivery

What you’ll gain

• Hands-on experience with real production codebase
• Practice in code refactoring and system unification
• Opportunity to improve your estimation and freelance workflow skills
• Possible long-term collaboration, if things work well
