About the opportunity:

• Java / Kotlin in production as the spine is what I’m shopping for first.

• Python as real backend work in the last few years is a big plus, I

• Ruby or Elixir in shipping work is a nice bonus on tiebreakers,

• A line or two on AI‑assisted coding in day to day work (Copilot, Cursor, whatever) still helps, we’re building in that world on Item.

• Commerce, catalog, inventory, enrichment, or messy domain modeling still wins for me over another payments microservice when everyone’s close on stack."
