Is your data scattered across SaaS tools, APIs, and databases, while your team still stitches reports together by hand? I build the pipelines that fix that. I'm a Data Engineer working across Google BigQuery and the Azure data stack (Data Factory, Synapse, Databricks), I pull data from any source, land it in your warehouse clean and modeled, and deliver Looker Studio dashboards your leadership actually trusts. I do this daily in production: I currently build revenue analytics infrastructure for a global SaaS company, syncing Stripe, Salesforce, and HubSpot into BigQuery, reconciling MRR down to the invoice, and powering dashboards used by finance and RevOps teams every day. On the Azure side, I've built multi-source reconciliation and deduplication pipelines in Databricks (PySpark, Delta Lake, medallion architecture) for enterprise clients. What I deliver: 🔹 API → Warehouse pipelines: Python integrations for Stripe, HubSpot, Salesforce, ad platforms, or any REST API, loaded into BigQuery or Azure on a schedule, with data quality checks built in 🔹 Azure Data Factory & Synapse: ADF pipelines, Synapse SQL/PySpark workloads, lakehouse setups, and migrations from legacy SQL Server to the cloud 🔹 Databricks: Medallion (Bronze/Silver/Gold) architectures, deduplication and MDM logic, SCD Type 2, Delta Lake optimization 🔹 BigQuery architecture: partitioned/incremental models, cost-optimized SQL, cross-cloud reads (yes, Synapse ↔ BigQuery included) 🔹 Dashboards: Looker Studio reports that answer business questions, revenue, billing, marketing, ops, not just display charts 🔹 Data cleanup & reconciliation: dedup, cross-system matching (CRM vs billing vs warehouse), audit queries that prove the numbers tie out Toolbox: BigQuery, GCP, Azure Data Factory, Synapse, Databricks, PySpark, Python, SQL, dbt, Delta Lake, REST APIs, Stripe, HubSpot, Salesforce, Looker Studio, PostgreSQL, SQL Server How I work: Clear scope before code. Documented pipelines you own, no black boxes. Async-friendly communication and regular updates, so you never wonder where things stand. If your data lives in five places and your reports live in none, message me with your sources and what you need to see, I'll reply with a concrete approach within 24 hours.
