Data Pipeline & ETL/ELT Engineering

Clean data doesn’t arrive — it’s engineered. I design and build the pipelines that move data from source systems into your warehouse reliably, with tested transformations your team can trust and maintain.

What’s Included

Source system integration and ingestion design
ELT pipeline implementation (Fivetran, Airbyte, custom Python)
SQL transformation layer — modeled, tested, and documented
Orchestration with Airflow
Incremental model design for production scale

Stack Experience

Python (pandas, SQLAlchemy) · Airflow · Spark · Fivetran · Airbyte · BigQuery · Redshift

I write transformation code the way software engineers write application code — version-controlled, reviewed, tested, and documented.

Data Engineering

End-to-end pipeline design and implementation — from raw source ingestion to clean, tested, production-ready data.

Frequently Asked Questions

Can't find what you're looking for? Reach out through the contact form below.

What kind of roles are you targeting?

I'm focused on Data Analytics Engineer and BI Leader roles — positions where I can own the full pipeline from raw data to executive-level insight. I'm especially interested in companies investing in a modern data stack (Python, BigQuery/Redshift, Tableau/Plotly).

What industries have you worked in?

I've built analytics solutions across retail, CPG, SaaS, and finance. I'm comfortable ramping quickly into a new vertical — data modeling and stakeholder communication patterns transfer across domains.

What does your technical stack look like?

Core: SQL, Python (pandas, SQLAlchemy), Spark. Warehouses: BigQuery, Redshift. BI: Tableau, Plotly, Google Data Studio, Excel. Orchestration: Airflow. Cloud: AWS, Azure, GCP. Git-based version control for all data work.

Are you open to remote, hybrid, or on-site?

I'm based in St. Augustine, FL and am open to remote-first roles. For the right opportunity I'm also open to hybrid arrangements within Northeast Florida.

Can you lead or mentor a data team?

Yes — I've led small analytics and BI teams, defined data governance standards, and mentored analysts growing into engineering roles. Building a healthy data culture is as important to me as building clean pipelines.

How do I get in touch?

Use the contact form on this site or email me directly at chrisrotunno@icloud.com. I typically respond within one business day.

Got a question?
I'll give you a straight answer.

No fluff. If I can't answer it, I'll say so.
