Selected work
PostgreSQL Connection Calculator
During a customer performance war room, I traced the pressure to the old configuration used for the initial migration and recommended safer workload and Puma limits within the database connection budget after migration. The errors stopped, developers kept working, and I built a reusable calculator for real-time calculations.

About
I moved from software engineering to systems administration and technical support, working where software, infrastructure, and people meet.
