Career path
Backend Engineer
Build depth across APIs, data, security, reliability, architecture, and engineering judgement.
- Staged roadmap
- Explainable recommendations
- Progress-preserving updates
Build the skills senior engineers actually use.
Follow a focused plan, learn the concepts that matter, practise real engineering decisions, apply them in tougher module checkpoints, and keep your next action clear.
- Free plan available
- No card required
- Progress stays with you

Focused by design
A clear career path, not an endless course catalogue.
KUNNR starts with a focused set of engineering tracks, then builds a personal plan around your current level, target role, available time, and learning priorities.
Personal plan
Start where your gaps are.
Your plan explains why each module belongs, what skill it develops, and which action should move you forward next.
- 01Engineering mindset
- 02API design fundamentals
- 03Data modelling for services
Initial tracks
Start with the engineering direction that fits.
Backend Engineering is available in Early Access. Frontend and AI Engineering are visible now and coming soon.

The learning loop
Learn, practise, apply, and improve.
Progress comes from completed learning and assessed work, not time spent watching content. Each activity keeps the next useful action clear.
Build your first plan- 01
Get an explainable plan
Choose a goal, track, target level, pace, language, and domain preference.
- 02
Learn and practise in order
Modules mix concise lessons and deterministic practice in one recommended activity sequence.
- 03
Apply the outcomes
Finish published modules with a tougher Apply practice when one is authored.
- 04
Improve from clear feedback
Review weak outcomes, retry practice, and let the same progress model update your plan.
Practice with purpose
Move beyond passive content.
Practice is embedded in the learning flow. Questions focus on engineering decisions, trade-offs, debugging, design, and communication rather than trivia.
- Ordered Lesson, Practice, and Apply activities
- Deterministic server-side scoring and feedback
- Language-aware code examples
- Review weak outcomes and retry immediately
Apply and improve
Know why you passed—and what to revisit when you do not.
Practice and Apply activities are marked deterministically. Passing work contributes to the same progress used by your Module, Career Path, and My Plan. If you miss the threshold, review the weak outcomes and retry.
- AttemptAnswer structured engineering questions.
- CheckReceive deterministic feedback and a clear result.
- ImproveReturn to the relevant material or retry.
