Don't let this gap widen
Why this program matters
Without mastery of Bun, your JavaScript development stays stuck at Node.js speed, losing up to 90% in execution time on critical tasks.
Untrained teams waste 35% of their dev budget on slow builds and bloated node_modules, causing project delays of 2 weeks on average.
In 2026, 68% of JS job postings require modern runtimes like Bun, sidelining outdated profiles and blocking promotions.
Every quarter without Bun skills exposes your company to competitors 10x faster, risking an estimated 20% loss in market share.
Act to avoid these costly traps.

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.
