About me

Technical depth, thoughtful communication, and a practical approach.

My background spans customer-facing application support, advanced troubleshooting, SaaS platforms, APIs, databases, cloud services, and web development. In my current role, I serve as a final technical escalation point, investigate complex product behavior, collaborate with engineering teams, and help translate technical findings into actionable guidance.

I’m also expanding my focus in data engineering through graduate study and hands-on projects involving AWS Glue, Apache Spark, Airflow, BigQuery, machine learning APIs, and data pipeline monitoring. I enjoy work that combines investigation, structure, and continuous improvement.
