• Comfortable working in large, established codebases and making safe changes.
• Experience designing services and APIs in cloud‑based, service‑oriented architectures.

• Clear, async‑first communicator who works well across time zones.

• Node.js
• React
• PostgreSQL or MySQL
• GraphQL
• AWS
• AI‑assisted development tools (e.g., Claude, Cursor, Codex)
