Summary

// about

IT Project Manager with close to 10 years of experience, recently focused on AI automation and building practical systems around LLMs.

Most of my work sits at the intersection of business and engineering — taking vague ideas or messy requirements and turning them into working solutions. I've led projects where we built automation pipelines, AI agents, and integrations that actually reduced manual work and made systems more predictable.

I'm comfortable working hands-on when needed (debugging, testing, integrations), but also managing teams, aligning priorities, and keeping projects moving. I care less about "AI for the sake of AI" and more about whether it solves a real problem and holds up in production.
