Don't let this gap widen
Why this program matters
Without Bun mastery, your JavaScript apps stay locked on slow Node.js, wasting up to 40% of development time according to 2024 benchmarks.
Endless npm builds raise project costs by 25% on average, delaying time to market and exposing performance failures in production.
Your career stalls against competitors who are 5x faster, while the company loses market share on unscalable apps.
Invest in this training now to avoid these traps and drive your skills to expert level.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
