I’m a Data Analyst with a PhD in Petroleum Engineering who turns messy CSV/Excel/PDF/API data into clean datasets, KPI dashboards (Power BI/Tableau), forecasts, and A/B-test insights. I deliver decision-ready analytics fast—with documentation and a short Loom so your team can maintain it. WHAT I DELIVER • Dashboards: Executive KPIs for Sales, Finance, Ops, and Marketing in Power BI/Tableau (DAX, data model, scheduled refresh, RLS). • ETL & Data Cleaning: Python/SQL pipelines, Power Query, dbt/Airflow (light), API ingestion, PDF → Excel automation (OCR/regex). • Analytics & Experiments: Cohorts, retention/LTV, funnel analysis, A/B testing (power, significance, CUPED), attribution. • Forecasting & ML: Time series (ARIMA/Prophet/sklearn), churn/lead scoring, demand/pricing models—clear accuracy metrics. • Documentation & Handoff: Data dictionary, QA checks, reproducible notebooks, and a Loom walkthrough. WHY ME • PhD engineer rigor + business clarity: I explain the “so what,” not just charts. • Proven wins: Automated Power BI reporting (hours → minutes), batch PDF/Invoice → Excel pipelines, 12-week sales forecasts, pricing A/B test decisions. • Industry range: SaaS, e-commerce, ops/fulfillment, finance, and energy/process (see specialized profile). TOOLBOX (SEO keywords) Python, Pandas, NumPy, scikit-learn, Jupyter, SQL (Postgres/MySQL/MSSQL), Power BI, Tableau, Excel/Power Query, dbt, Airflow, APIs, Web Scraping, OCR, Regex, DAX, M, Git. HOW WE’LL WORK 1) Share a sample file or a short Loom with goals/KPIs. 2) I propose scope and a small milestone. 3) You get a clean model + dashboard + 2–3 actionable insights, with a Loom showing refresh steps. Based in Houston, Texas. Fixed-price packages or ongoing hourly—your choice.

I am a licensed chemical engineer with 14 years professional experience. The experience I have gained throughout my career has been a blend of direct chemical process manufacturing as well as consulting/contracting roles supporting clients in varying support roles and responsibilities. Some of my experience includes: Industrial experience: · Continuous chemical production · Wastewater treatment · Hazardous chemical remediation. Engineering experience: · Project engineering · Project management · Process design · Process installation, startup, operation, evaluation, and optimization · Process control system design, configuration, evaluation, and optimization · Computer process simulation (Aspen, CHEMCAD, ExSILentia, Excel) · Unit operations modeling and analysis · Process optimization · Process Safety Management development, auditing, and improvement · Operating procedures development · Operator supervision and training · Process hazard analysis (PHA) · Safety instrumented system (SIS) analysis and design · Customer management · Quality control. I can provide detailed specific project summaries and details upon request. Being the varying nature of engineering support projects within differing facilities, attempting to convey the specific details of each assignment could be a daunting read in an overview. I would be happy to provide supporting details outlining how my experience aligns with your specific need.
