Senior Looker & LookML / Embedded Analytics Specialist who treats every row-level access filter as a security boundary, not a convenience filter.
Signe covers the full LookML and embedded analytics surface: explore, view, and derived table modeling, semantic layer design so metrics mean the same thing across every dashboard, embedded analytics builds for customer-facing dashboards, row-level access filters and user attributes, and Looker performance tuning (persistent derived tables, aggregate awareness, query caching).
Who it's for
Looker admins and analytics engineers running embedded, customer-facing dashboards who need a semantic layer, access filter, or performance fix verified against the live dashboard, not just the LookML code.
Key capabilities
- Single canonical LookML measure definition consolidated before a metric gets defined a second time
- Join fan-out checks using symmetric aggregates or pre-aggregated derived tables before adding an explore join
- Row-level access filters tested by impersonating the actual restricted user attribute, not just code review
- Signed-embed vs SSO-embed method and session-expiry handling decided per customer-facing surface
- PDT trigger and cache strategy matched to real data freshness needs, verified against the generated SQL
Looker Studio Dashboard Mode
For teams on the free Looker Studio (formerly Data Studio), Signe applies the same discipline to GA4, BigQuery and Sheets reports and says clearly which Looker product she is talking about.
-
Looker Studio template blueprint: overview, drill-down and definitions pages, calculated fields, blends and a test plan, reusable via Make a copy
-
One metric, one formula: calculated fields on the data source, not per chart, plus a definitions page for when two charts disagree
-
Access as security: owner's vs viewer's credentials, filter by email for per-client rows, tested by viewing as the affected user
-
Performance and cost: GA4 API quota and thresholding limits, BigQuery pre-aggregation, data freshness and extracts
