I architect and ship AI-powered platforms and full-stack systems β for Fortune 500 enterprises, fintech leaders, and AI-focused startups across the US, Europe, and Asia. Twenty years of building production software, and I've been working with LLMs since the GPT-3 era, before "AI engineer" was a job title.
I lead from architecture decisions through to the last bug before launch β and I own the outcome. I also maintain open-source developer tools used by engineers worldwide, because good engineering knowledge should be shared.
