It takes a lot to turn messy data into real time actionable insights. You need a professional who can guide you through the entire process and guarantee an accurate , robust model that is ready to scale. I handle the full project: requirements gathering, data modelling, ETL pipeline design, report development, stakeholder customisation, and handover documentation. Clients come to me to fix existing dashboards and data models, or to consolidate data spread across multiple systems into a single source of truth everyone can trust. My background covers 5+ years of analytics and data engineering work across multiple industries. I hold a B.S. in Information Science from CU Boulder, am finishing an M.S. in Data Science at CSU Global, and hold the DP-600 Microsoft Fabric Analytics Engineer certification. I am also a licensed commercial pilot, so you can expect proactive communication and sound judgment under pressure. All of my previous clients and employers will provide positive references upon request. Here is a sample of recent work: For a multi-property hotel group in Canada, I built a 6-page Power BI dashboard from scratch. The data model used a star schema with six fact tables connecting financial, maintenance, revenue, people, reputation, and operational data. Each page was designed around the specific needs of the department using it, based on direct input from those stakeholders. I owned the project end-to-end from the first requirements conversation through deployment and documentation. For an e-commerce company, I built a 7-page sales dashboard with the specific KPIs a major retail partner required before signing a vendor agreement. The same underlying data model was adapted for internal reporting at every level of the business, with access scoped by role. I maintained that dashboard and the ETL pipeline behind it for two years as requirements evolved. I also built a predictive model to replace a departing purchasing manager, handled a full CRM migration to HubSpot that a vendor had quoted at $5,000, but I completed it for $500, and conducted market basket analysis that informed website development. At a nonprofit, I built Power BI and Tableau dashboards to track program KPIs, grant performance, and conversion-funnel analytics. I led the ETL work for an applicant-tracking system and produced financial dashboards supporting grant proposals totalling over $1M. I integrated GA4 with Google Ads, built a funnel report that identified where users were abandoning the page before donating or reaching out, and collected and analysed data for a study on paralysed veterans presented to CU Anschutz. At a legal office, I deployed a Power Apps application to automate reception duties and build a structured data record that fed into a Power BI dashboard that stakeholders monitored on an ongoing basis. Earlier in my career, I worked at the National Centre for Atmospheric Research, where I aggregated and processed large-scale time-series climate datasets on the Cheyenne high-performance computing system. That work built the data engineering foundation I bring to every project now. Power BI is my primary platform and where I do my deepest work. It connects to virtually any data source, and I work with all of them: SQL databases, Snowflake, AWS (S3 and Athena), flat files, APIs, Excel, SharePoint, and GA4. If it has data, I can connect it, model it, and build reliable reporting on top of it. For Snowflake and Microsoft Fabric specifically, I work the full stack: star schema design, ETL loading via Apache Airflow and dbt, performance tuning, and resolving access and permission issues between systems. I work with a fixed scope and clear deliverables at each stage, so there are no surprises mid-project. Before I write a single measure or build a single visual, I make sure I understand what decisions the output needs to support. Stack: Power BI, DAX, M, Power Query, SQL, Python, R, Snowflake, Microsoft Fabric, AWS (S3, Athena), Apache Airflow, dbt, Power Apps, Looker Studio, GA4
