Aleksi Kallio
AI Solutions Architect. Builder. Former CTO.
I design AI and cloud systems that hold up in production, EU-sovereign when it matters, and I still write the code.*
* Only occasionally these days. Mostly AI writes the code and I review and approve it.
What I do
AI & agents
Multi-agent systems, RAG pipelines and AI orchestration, on GCP Vertex AI, Mistral and Azure AI Foundry.
Cloud architecture
AWS serverless, CDK, Terraform, event-driven and hexagonal architecture. Built to be boring in production.
Sovereign when needed
EU-resident stacks, EU inference and EU vendors, for when data location actually matters.
Technical leadership
CTO experience: strategy, team practices, release processes, ISO 27001.
