When to Call me

Teams usually reach out when systems are working — but becoming harder to reason about.

Architecture problems rarely appear as outages first. They appear as uncertainty: permissions behave inconsistently, integrations feel fragile, or new features require touching too many parts of the system.

I am typically brought in when a platform is entering one of the following transitions — either to provide architectural guidance, or to work directly with engineering teams through focused consulting and training engagements.

Identity and Permissions Are Becoming Difficult to Manage

• Authentication works, but authorization logic is scattered.
• Permissions differ across services or tenants.
• Role models no longer match product complexity.
• Enterprise SSO or LDAP integration is being introduced.
• Teams are unsure where authorization decisions should live.

In these situations, I help teams redesign authorization models and can provide hands-on training sessions covering identity architecture, RBAC design, and practical authorization patterns.

Multi-Tenant Complexity Is Increasing

• New customers require isolated workflows or configurations.
• Tenant boundaries feel unclear.
• Billing, permissions, and tenants are tightly coupled.
• Feature development introduces tenant-specific exceptions.

Engagements often combine architecture consulting with team workshops focused on designing sustainable multi-tenant systems and avoiding common scaling pitfalls.

Payments and Billing Are Affecting System Design

• Subscription workflows are expanding rapidly.
• Payment logic spreads across multiple services.
• Webhooks and asynchronous events become difficult to reason about.
• Ownership of payments across tenants or users is unclear.

I help teams structure payment-aware architectures and provide practical training on integrating payment systems safely into backend platforms.

Integrations Are Multiplying

• CRM, financial, or external APIs are accumulating.
• Integration failures affect unrelated parts of the system.
• Data synchronization rules are unclear.
• Teams lack consistent integration patterns.

Consulting engagements often include collaborative architecture sessions or on-site workshops to establish integration design principles teams can reuse independently.

Mobile or External Clients Cannot Be Fully Trusted

• APIs are exposed to mobile or third-party clients.
• Backend assumptions rely heavily on client behavior.
• Security concerns arise despite correct authentication.
• Device variability introduces unpredictable behavior.

I work with teams to refine backend trust models and can deliver training focused on secure API design and mobile-aware backend architecture.

The System Is Scaling Faster Than Its Original Design

• Engineers hesitate to modify core backend logic.
• New features increase complexity disproportionately.
• Architectural decisions feel inconsistent.
• Teams need alignment before continuing development.

These engagements frequently combine architectural review with structured training modules that help engineering teams adopt shared architectural principles moving forward.

Training & On-Site Consultancy

In addition to advisory work, I provide focused training and on-site consultancy designed for engineering teams working with growing SaaS platforms.

Training sessions are practical and architecture-driven, typically covering:

• Identity and authorization architecture
• RBAC and policy-based access design
• Multi-tenant backend architecture
• Payment and subscription system integration
• Integration architecture patterns
• Secure backend design for mobile and distributed clients

Sessions are tailored to existing systems and emphasize real-world architectural decision-making rather than theoretical instruction.

What Working Together Looks Like

Engagements typically begin with an architectural discussion or system review. Depending on team needs, this may evolve into advisory support, collaborative architecture design, or structured training sessions delivered remotely or on-site.

The goal is not to replace engineering teams, but to provide clarity and shared understanding so teams can continue building confidently.
