About

I’m Hugo Nissar, a MarTech engineer based in Stockholm, Sweden.

I build open-source pipelines for marketing data on Google Cloud — the kind of infrastructure that sits between Google Analytics 4, BigQuery, and Google Ads and that most companies end up rebuilding from scratch. My focus is on systems that are cost-capped, and production-hardened by default.

What I work on

• BigQuery + BigQuery ML — purchase propensity, churn, LTV models trained directly on GA4 export data.
• GA4 Measurement Protocol — pushing model output back into GA4 as user properties so it shows up in audiences and Google Ads remarketing.
• Model Context Protocol (MCP) servers — connecting AI agents (Claude, ChatGPT, Cursor, Gemini) to enterprise data with hard guardrails.
• Cloud Run + Cloud Functions — serverless and scale-to-zero deployments.
