Most technical teams hit the same walls when adopting AI.
Developers use different tools, everyone prompts differently, no one knows what's safe to send to AI and what isn't. You're missing guardrails.
Your team experiments with AI through trial and error. No best practices, no shared prompts, no way to measure if AI is actually helping.
Other teams have AI workflows set up systematically — with guidelines, training, and measurable results. You're just getting started.
I help technical teams who want to actually use AI — not just talk about it.
You need an AI strategy for engineering. Not another sales deck — a real plan for integrating AI into your dev workflow.
Your team spends hours on boilerplate and code review that AI could handle in minutes. You want someone to train the whole team.
You want to learn how to effectively use Copilot, Claude, and other AI tools in your daily workflow.
From first call to real results in three steps.

Read more3 people, 2 weeks of handoffs vs 1 person, a few hours of focused work
3+ people — PM, FE Dev, BE Dev, QA
Writes spec, sends to dev
Reads spec, asks questions, waits for answers
Implements frontend (BE dev waits or works separately)
Implements backend (blocked until API spec is final)
Tests, writes bug reports
Reads report, fixes bugs
Retests everything again
Bug found → back to dev → QA → repeat

Just laptops and motivation. I handle everything else — tools, materials, and exercises tailored to your stack.
Yes, all formats work online. Workshops, training, and consulting run smoothly over video.
AI tools are language-agnostic — the training works for any stack. TypeScript, Python, Go, Java, C# — the techniques are universal.
Ideal group size is 5–15 developers. Enough for shared learning, small enough so nobody gets lost.
Even better. I'll audit your current workflow, identify gaps, and level up the whole team.
I measure time on typical tasks before and after training. Concrete numbers — not feelings.
