Terragrunt + GitHub Actions Skills: Schema/metadata-driven system design (this project uses per-role schema overlays across 11 distinct roles, not off-the-shelf RBAC).
JSONB-based PostgreSQL modeling.
Strong code review instincts around authorization/access control.
Integrating multiple third-party APIs with graceful handling of partial failures.
DevOps-adjacent comfort (Docker, IaC, CI/CD, Azure).
Responsibilities: Own architectural decisions for a large, actively evolving codebase in a compliance- and finance-sensitive domain (KYC/KYB, points/rewards economy, card issuance).
Extend the generic-entity/schema system without regressions.
Lead integration work with external providers (SmartSearch, Salesforce, Xero, Pannovate, SendGrid).
Review code with a security-first eye, particularly on permission/access-control gaps.
