Your dashboards are only as reliable as the pipelines behind them. I help teams fix broken data flows, automate reporting systems, and build trusted data warehouses using dbt, Airflow, Snowflake, BigQuery, Python, and SQL. I am a Top Rated Data Engineer with 6+ years of experience building ETL/ELT pipelines, cloud data warehouses, API integrations, and analytics-ready data models for SaaS, e-commerce, marketing, finance, and operations teams. Most clients come to me when their data is scattered across tools, reports do not match, pipelines keep breaking, dashboards are slow, or teams are still relying on spreadsheets for critical reporting. I help fix the root cause by building clean, automated, and scalable data infrastructure. What I can help you with: • Build ETL/ELT pipelines from APIs, databases, CRMs, ad platforms, SaaS tools, and spreadsheets • Design and optimize cloud data warehouses in Snowflake, BigQuery, Redshift, PostgreSQL, and ClickHouse • Create clean dbt models for revenue, marketing, sales, product, finance, and operations reporting • Automate workflows using Airflow, Python, SQL, cloud functions, and scheduled jobs • Integrate tools like HubSpot, Salesforce, Shopify, GA4, Meta Ads, Google Ads, Airtable, Stripe, and internal APIs • Fix duplicate records, broken joins, mismatched KPIs, slow queries, and unreliable dashboards • Set up data quality checks, reconciliation workflows, documentation, and monitoring • Prepare clean reporting layers for Power BI, Tableau, Looker Studio, Metabase, Superset, and executive dashboards Common problems I solve: • “Our dashboards do not match our source systems.” • “Our reporting is still manual and takes too much time.” • “We have data in too many tools and no single source of truth.” • “Our warehouse is messy and nobody trusts the numbers.” • “Our pipelines are slow, broken, or not scalable.” • “We need someone to clean up our dbt, SQL, or data models.” Recent work includes modern SaaS data stacks, marketing analytics pipelines, retail data warehouse migrations, GA4 and BigQuery reconciliation, CRM reporting foundations, and automated BI-ready datasets. My focus is simple: build data systems that are accurate, maintainable, and easy for your team to trust. Send me a message with your current data stack and the problem you are trying to solve. I can help you identify the best way to fix it.
