Systems Architecture Portfolio

Multi-channel financial reconciliation platform normalizing SWIFT registry, M-Pesa B2B, and SAP ERP data streams into secure PostgreSQL registers with role-based access control and full audit logging.

• Automated discrepancy-detection triggers cut manual audit review by ~90%
• Data classification, retention, and encryption controls mapped to HIPAA & SOC 2 objectives
• Risk register and data-flow documentation used in vendor due diligence

Production web platform with authenticated, per-user data isolation (Postgres row-level security), server-side AI generation, and LinkedIn integration — the same access-control patterns used for PHI-bearing systems.

• Per-user tenancy enforced at the database layer, not the UI
• AI-tailored, ATS-optimized resume versions and cover letters per job listing
• Server-only secrets and least-privilege access throughout

Enterprise-wide evaluation of state records and data-handling workflows against public-records, confidentiality, and retention policy — producing SOPs, control monitoring, and remediation pathways for modern software integrations.

• Risk assessments and control monitoring for restricted data systems
• Policy requirements translated into technical system requirements
• Audit-ready SOP documentation
