Milan N.

I help businesses connect disconnected data sources, automate manual processes, and build reliable data systems that make reporting and decision-making easier. My background combines data engineering, data migration, ETL/ELT pipelines, API integrations, business process automation, and BI reporting. I've worked with Google BigQuery, SQL, Python, Power BI, Looker Studio, n8n, Power Automate, Google Apps Script, Excel, Google Sheets, and Microsoft Dynamics 365. Most of my projects involve one or more of these: ➤Building automated pipelines that extract, transform, and load data from APIs, databases, cloud platforms, and business applications. ➤ Connecting platforms such as Google Ads, Meta Ads, TikTok Ads, Snapchat Ads, GA4, Klaviyo, Shopify, WooCommerce, and CRMs into centralized reporting systems. ➤ Designing BigQuery data warehouses, developing SQL transformations, consolidating datasets, and creating reliable reporting models. ➤ Automating repetitive workflows using n8n, Power Automate, Python, Google Apps Script, and API integrations. ➤ Supporting enterprise data migrations, including Microsoft Dynamics 365 and Business Central, with a focus on data transformation, importing master data, reconciliation, and validation. ➤ Developing automated dashboards and reporting solutions using Power BI, Looker Studio, Excel, and Google Sheets. Recent project experience includes: • Building an end-to-end data infrastructure for an ecommerce business, integrating advertising platforms, GA4, Klaviyo, and WooCommerce into Google BigQuery, with automated pipelines and reporting-ready datasets. • Developing automated workflows that connect APIs, spreadsheets, databases, and business applications, reducing manual data processing and reporting. • Supporting enterprise-scale data migration projects involving customer, vendor, contact, and other master data, including data validation and reconciliation across environments. I'm particularly useful when a project requires more than just writing a script or creating a dashboard. I focus on understanding how the business operates, identifying the right data flows, and building solutions that are accurate, scalable, and easy to maintain. My goal is to deliver systems that work reliably, minimize manual intervention, and continue providing value long after the initial implementation.
