Power BI Developer + Data Engineer | Databricks, ADF, SQL, Fivetran
Power BI developer + Data Engineering — I build the automated pipelines (Databricks, ADF, SQL, Fivetran) and the dashboards leadership trusts, end to end. If your team is still pulling numbers by hand, stitching exports together, and quietly not trusting what's in the report — your data isn't slow, it's unbuilt. And every decision made on top of it is shakier than it should be. I'm a data engineer and BI specialist with 13+ years building the full path from raw, messy source data to the dashboards leadership actually trusts. Co-founder of GrowthBI, an analytics consultancy serving scaling companies across Australia, Europe, and the US. Here's what makes me different: most freelancers do one half. Pure data engineers hand you clean tables and no story. Pure dashboard builders make polished reports on top of data that breaks every week. I build both halves — the pipeline and the reporting — so you hire one person instead of managing two. 80%+ of my clients come back for follow-on work. Where I deliver the most impact: → Data pipelines & automation — Fivetran, DBT, SQL pipelines that ingest from SAP, CRMs, ad platforms, and spreadsheets, model the data in Databricks/BigQuery, and refresh on a schedule so reports build themselves → Data modelling & warehousing — clean, documented, single-source-of-truth tables your whole team can rely on → Power BI & Looker Studio dashboards for marketing, product, sales, and finance leadership → Executive reporting — YTD, MTD, YOY, and scenario comparisons leadership can act on → Customer & growth analytics — RFM modelling, cohort analysis, churn prediction, CAC vs. LTV, channel attribution → Row-level security (RLS) & governance for multi-team and multi-entity reporting Results I've delivered: → 10x growth in customer acquisition — surfaced channel-mix insights that reshaped how a leadership team allocated marketing spend → 10% churn reduction — identified the highest-risk customer cohort with RFM segmentation and built a live re-activation tracker for the sales team → Prevented significant revenue loss — caught a payment failure from a default product setting before it compounded, with a live monitoring dashboard run until the fix shipped My core stack: SQL · DBT · Fivetran · Databricks · BigQuery · Power BI · DAX · Power Query · Alteryx · SSIS · Excel Industries: E-commerce · SaaS · Real Estate · Financial Services · Insurance · Consumer Goods Clients I've worked with: Rate My Agent · Keep It Cleaner · Montgomery Homes · Peeplcoach · Paylater · Joolca I work directly with C-suite leaders, senior leadership teams, and cross-functional analysts. I understand what each team needs to answer — and I build the data layer and the dashboards that answer it, without a manual every time.
