4+ years building BI end-to-end Infrastructure. I sit with the ambiguity, ask what your team hasn't, and translate fuzzy business goals into a clear data model and KPI framework that holds up under scrutiny. ๐ง ๐๐ก๐๐ญ ๐ ๐๐ซ๐ข๐ง๐ ๐ญ๐จ ๐ฒ๐จ๐ฎ๐ซ ๐ญ๐๐๐ฆ ๐น Ambiguity โ Clarity: I define the right questions and metrics before building anything, so you measure what matters, not what's easy. ๐น Semantic & Data Modeling: Star schemas, slowly-changing dimensions, reconciled grain, single source of truth ๐น Scalable Architecture: Pipelines and models designed for "Day 2", maintainable, cost-aware, documented, built to grow instead of breaking at scale. ๐น Context Integration: I unify Stripe, Shopify, Zoho, GA4, Ads platforms, etc. and CRMs into one coherent ecosystem that mirrors how your business actually operates. ๐น Narrative & Decision Design: Every visual answers a business question and points to an action, analysis a CEO can act on in seconds. โ๏ธ ๐ง๐ฒ๐ฐ๐ต๐ป๐ถ๐ฐ๐ฎ๐น ๐ง๐ผ๐ผ๐น๐ฏ๐ผ๐ ๐น BI & Viz: Power BI, Looker Studio, Zoho Analytics, Metabase, Apache Superset, Domo, Databox ๐น Modeling & Query: SQL, DAX, Power Query (M), Python, dbt, Excel ๐น Warehousing: BigQuery, Cloud SQL, Snowflake, SQL Server, MySQL, Firebase ๐น Pipelines & ETL: Make, n8n, Fivetran, Apps Script, Cloud Run, Windsor AI, Coupler IO, Supermetrics ๐น Sources: Stripe, Shopify, Zoho CRM, GA4, Google/Meta/TikTok Ads, Search Console, etc. ๐น AI layer (the plus): OpenAI & Claude APIs, Claude Code, Codex, conversational analytics, anomaly detection, predictive models, and agent workflows for automated briefings & alerts ๐ ๐ช๐ต๐ฎ๐ ๐ฆ๐ฒ๐๐ ๐ ๐ฒ ๐๐ฝ๐ฎ๐ฟ๐ ๐น Business-first, not tool-first: I start with your objectives and constraints, not your dataset. ๐น End-to-end ownership: From auditing sources and defining KPIs to modeling, building, and publishing, I run the full lifecycle. ๐น Transparency: You own your data and infrastructure.
