Backend Developer for PostgreSQL Tasks

Looking for a backend developer to support our existing dev team on defined, scoped tasks — NOT to own the whole codebase. This is task-based work, not a full-time replacement role. You'll work on things like: Writing/optimizing PostgreSQL RPC functions and triggers, Debugging data integrity issues (duplicate records, enum mismatches, stale joins), Row-Level Security (RLS) policy work in Supabase, Idempotent upsert logic for automation sync (Make.com → Postgres).
