AboutBuilding intelligent systems at the
Building intelligent systems at the
intersection of cloud & AI
I design and ship AI-powered cloud solutions end-to-end — taking problems from fuzzy business need to production-grade systems. With almost 10 years of enterprise software delivery, my focus is AI engineering and solution architecture in cloud: agentic LLM systems, retrieval-augmented generation (RAG), evaluation frameworks, and cloud-native platforms that are secure, observable, and cost-aware.
At risktec I work on AI for the risk industry — where the domain is unforgiving and "roughly right" isn't good enough. My conviction: models change, prompts change, so nothing ships without evaluations behind it.
