–Service-based cost engine querying 10+ static cost tables across character and weapon upgrade paths
–3-to-1 synthesis detection identifying conversion opportunities from surplus lower-tier materials
–EXP potion equivalence logic reconciling cross-tier satisfaction against plan requirements
–Versioned REST API with hashed token authentication, rate limiting, and integration test coverage
–Real-time inventory updates via Hotwire Turbo Streams, entire synthesis families re-render on edit

About

The person behind the work

Software engineer, early career, graduating June 2026 with an AAS in Software Design from Walla Walla Community College. Currently working in Tech Services at Walla Walla Community College, supporting campus operations and analyzing lab usage data to inform department resource allocation decisions.

I build on the side with the same discipline I bring to work. Pangu Terminal is live in production.

I read, I go to the gym, I show up consistently.
