Tomasz Guściora
Claude Code Trainer & Hands-on Practitioner
13 years in the industry - most of it in data science. 750+ hours in Claude Code, since back when something broke every week (and I mean every week). Production AI/ML I've shipped: fraud detection, customer segmentation, proposal generators, startup prototypes. I'm not a trainer-of-trainers. I teach what I actually do at the keyboard every day.
I understand LLM architecture not from articles - from banging my head against it during real implementations. That's why I can explain to your seniors why Claude Code occasionally "hallucinates" and, more importantly, how to write code that keeps that risk on a leash.
Substack DemystifAI - three years of poking at large language models: token economics, agents, AI in the code-generation loop. GitHub claude_code_common_base - my own Claude Code template, with hooks, subagents, MCPs. Audit the code before you book the call. Seriously.
6 years at Citi (Warsaw, London, Jakarta) taught me how big orgs actually work: compliance, governance, procurement, NDA, GDPR. I know what derails an adoption in a software house - and it's never "just the technology". It's people. It needs a shift in how the team thinks. I'll help you with both.
