À propos de John
Senior enterprise integration architect delivering production LLM and agentic AI on AWS and GCP for regulated enterprises. 18 years at IBM Global Business Services (Federal) leading integration and modernization for mission-critical programs. 8+ years independent GCP production data engineering for regulated data pipelines in life-sciences-adjacent domains. Hands-on production LLM and agentic AI engineering since 2023 — multi-model orchestration, hybrid retrieval, and EU AI Act-aware sovereign-cloud patterns.
Integration-first mindset applied to AI: I treat LLM and agentic deployments as systems-integration problems — data flow, orchestration, governance — not research problems. Comfortable in compliance-constrained environments where hallucinations, data sovereignty, and audit trails are non-negotiable.
Recent independent R&D — hybrid RAG + multi-model LLM orchestration on Apple Silicon. Explores local-inference optimization, retrieval routing, and persona-scoped knowledge firewalls.
Operating through Oivallus AI, LLC (Washington state, formed April 2026); underlying independent consulting continuous since 2017. Finnish Oy transition scheduled post-July 2026 via the MSA affiliate-assignment clause — engagement continuity through the cross-border founder transition, not a restart. Remote-only delivery. AWS Solutions Architect – Associate and AWS Machine Learning Engineer – Associate certified; AWS Generative AI fast-track planned.
Milestone-based invoicing preferred.
