You will get Python Data Automation, Cleaning & ETL Pipelines
Project details
I help businesses automate repetitive data work using Python so they can eliminate manual reporting, reduce errors, and trust their analytics.
Many teams struggle with messy Excel files, inconsistent datasets, manual data cleaning, or unreliable reporting pipelines. I solve these problems by building clean, scalable Python automation and ETL pipelines that extract, transform, validate, and deliver analytics-ready data.
With 7+ years of experience in Business Intelligence and Data Analytics, I’ve built Python pipelines that support dashboards, cloud data warehouses, and self-service analytics for startups, SaaS companies, and enterprise teams. My focus is on writing clean, well-documented code that is easy to maintain and aligned with real business goals—not one-off scripts.
You’ll receive reliable automation, clear documentation, and a solution designed to scale as your data grows.

Winter Garden, United States - 7:29 pm local time
I am a Senior Business Intelligence Analyst and Data Analyst with 7+ years of professional experience, working with global organizations such as the World Bank, SaaS companies, consulting firms, and mission-driven organizations across finance, technology, sales, marketing, and global health. My work focuses on transforming raw data into accurate insights, scalable reporting solutions, and executive-ready dashboards that leadership teams can trust.
I specialize in Power BI, SQL, Snowflake, Python, and Tableau, helping organizations eliminate manual reporting, improve data accuracy, and build modern analytics environments. I work end-to-end across the data lifecycle—data extraction, cleaning, transformation, modeling, visualization, automation, and stakeholder enablement—so clients get solutions that are not only technically sound but also aligned with real business goals.
Many of my clients come to me with common challenges: outdated Excel reports, slow dashboards, inconsistent numbers, disconnected data sources, or lack of visibility into KPIs. I help solve these problems by designing robust SQL queries, automated ETL pipelines, and interactive dashboards that provide real-time insights and long-term scalability.
How I Help Businesses:
• Convert manual Excel and CSV reporting into fully automated dashboards
• Build executive, sales, marketing, finance, and operations dashboards in Power BI and Tableau
• Design optimized SQL reporting layers for accurate and fast analytics
• Migrate legacy or on-premise databases to Snowflake and cloud data warehouses
• Improve dashboard performance, refresh speed, and data reliability
• Enable self-service analytics so teams can answer questions independently

• Built SQL and Python ETL pipelines to support scalable, self-service analytics
• Increased sales revenue by 15% by automating CRM data and surfacing actionable insights

Technical Expertise:
I work daily with Power BI (DAX, Power Query, data modeling, performance optimization), SQL (SQL Server, PostgreSQL, Oracle, MySQL), Snowflake, and Python (Pandas, NumPy, automation scripts). I also have extensive experience with API integrations, CRM analytics, data cleaning and validation, data warehousing concepts, and cloud platforms (AWS, Azure, GCP).
I am highly skilled in data visualization, dashboard design, data storytelling, and translating technical insights into business language. My background in consulting and training allows me to work effectively with both technical teams and non-technical stakeholders.
