Backend, payments & compliance advisory
Fractional architecture help for teams building in regulated spaces. I help you design secure payment, auth, and data systems, and get through the security review, without needing a full-time senior hire.
Where I help
- Payments & fintech architecture: secure payment flows, encryption (KMS, Nitro Enclaves), fraud reduction, PCI DSS alignment.
- Auth & identity: OAuth/OIDC, passkeys, multi-tenant access control, session and token design.
- Compliance readiness: HIPAA, PCI DSS, COPPA, GDPR-aligned architecture, audit logging, and security-review prep.
- Cloud & cost: AWS/OpenStack architecture reviews and cloud-cost reduction (I've cut infra cost by up to 60%).
- Scaling & reliability: Node.js/TypeScript at scale, microservices, observability.
How it works
Engagements are scoped to what you need:
- Architecture review: a focused audit of your backend/security posture with a written findings + recommendations report.
- Fractional advisor: ongoing, a few hours a week: design reviews, unblocking, and mentoring your team.
- Project sprint: a defined build or hardening engagement with a clear deliverable.
Pricing is quoted per engagement, based on scope. Tell me what you're building and I'll come back with a proposal.
