# AI Developer Training

Hands-on training that moves engineers from ad hoc AI experimentation to deliberate, effective daily use.

_[Expert Engineering](/ai-native-engineering) › [Team Training](/capabilities/team-training)_

**From dabbling to deliberate AI engineering**

Most engineers use AI at a fraction of its value. We train teams hands-on, in your codebase - context engineering, agent workflows, validation habits - the same practices our own delivery teams use every day.

## Team Training

- Industry runs on our tooling · 50M+ OSS downloads / month
- React Foundation Founding Member · 300+ commits to React Native · Contributing since 2016
- 2.8x Knowledge increase over 8 weeks
- 100+ Enterprise projects delivered
- ISO 27001 certified
- Agent Skills · Callstack’s engineering practices packaged as reusable instructions for coding agents.
- “The 1:1 sessions were nice. Good to have a dedicated time for questions.” — John, HelloFresh

## What you get: Training that changes Monday morning.

- **Hands-on, in your codebase** Exercises on your real repositories and tickets, not toy examples.
- **Agent workflow mastery** Planning, delegating, and orchestrating agents beyond autocomplete.
- **Context engineering** Structuring repos, docs, and skills so models perform.
- **Judgment and review habits** Validating AI output fast without rubber-stamping it.
- **Role-based tracks** Different depth for seniors, juniors, and leads.
- **Practice that sticks** Office hours and follow-ups after the workshop, so habits survive deadlines.

## How we work together: Training shaped around your team, codebase, and roadmap.

### Extend your team (1 week)
Our senior engineers join your team to ship features, guide technical decisions, and strengthen delivery.
- Your roadmap and workflow
- Expertise shared as we work
- Flexible timezone coverage
### Deliver a project (1-12 months)
We take agreed work from technical planning to release, with clear responsibilities and progress you can see.
- 3 Callstack engineers ship like 6
- Impact visible before sprint two
- End-to-end delivery
### Solve specific challenge (as needed)
We address a performance, migration, or infrastructure challenge, or run training around your team’s needs.
- Focused reviews or implementation
- Knowledge your team keeps
- Outcomes guaranteed with contract

## What shipping at AI speed looks like.

- [Training HelloFresh Engineers to Build Production Apps With React Native](/case-studies/training-hellofresh-engineers-to-build-production-apps-with-react-native): 2.8x increase in knowledge over 8 weeks (25% → 71% assessment scores)
- [Enhancing Performance of Momo's Super App With Re.Pack](/case-studies/improving-performance-of-super-app-for-momo)

**Train like the teams that ship with agents.** Practical AI engineering skills, taught by people who use them in production. [Train my team](/contact)

## Let’s find the right path for your product.

**What level do engineers need?**

Any. Tracks split by experience: juniors build fundamentals and safe habits; seniors focus on orchestration, architecture, and review at agent speed.
**Remote or on-site?**

Both. On-site accelerates the hands-on parts; remote works well for distributed teams. The format follows your team, not our preference.
**How large can a cohort be?**

Around ten keeps it interactive; larger groups split into parallel cohorts with the same curriculum.
**How long is the program?**

Typically two to five days of workshops spread over weeks, plus follow-up office hours. Compressed formats exist for leadership overviews.
**Is it tied to specific tools?**

Grounded in the tools you actually use - Claude Code, Cursor, Codex - with technique that transfers when tools change.
**How do we know it worked?**

Pre and post signals: adoption, acceptance rates, and rework on trained teams. Pair it with the Adoption Dashboard and the delta is visible.
