For engineering managers
Training that justifies itself.
Leadership wants numbers. Each course has defined skills, measurable completion, and costs less per developer than a single day of conference attendance.
Defined outcomes per course
Dart fluency. Flutter architecture. SOLID principles. Kubernetes operations. Each course has specific, demonstrable skills.
Exercises prove understanding
Every lesson runs tests against the developer's code. Completion means they solved the problem, not just watched it.
Scales with your team
Team plans cover your whole org. Add developers as you hire. One subscription, one platform, every course included.
Less than a conference ticket per developer
Ongoing access to every course. No per-seat surprises.
