Jonathan Ascona

I help businesses turn messy data into clear insights and automated systems that drive better decisions.

I’m a Data Analyst with hands-on experience in Python, SQL, machine learning, and dashboard development. I’ve worked with real-world datasets across operations, customer analytics, and performance tracking, building solutions that improve efficiency and uncover actionable insights.

My experience includes:
• Building dashboards (Tableau, Excel) for business reporting and decision-making
• Writing SQL queries to extract, clean, and analyze large datasets
• Developing Python workflows for data cleaning, automation, and analysis
• Supporting machine learning projects (model training, evaluation, preprocessing)
• Translating business problems into data-driven solutions

I’ve worked with cross-functional teams to deliver analytics solutions that improve operations and provide clear, usable insights; even for non-technical stakeholders.

I focus on:
✔ Fast, clean, and reliable data solutions
✔ Clear communication
✔ Delivering results that actually help your business grow

Whether you need dashboards, data cleaning, automation, or insights from your data; I can help.
