Senior Backend Engineer & Systems Consultant specializing in SaaS architecture, multi-tenancy, APIs, integrations, and production reliability. When a project needs end-to-end delivery, I can also carry it through frontend and Flutter.
Most work starts as one of these and expands into architecture ownership.
API design, database architecture, queues, caching, and system design for products that need to grow without turning the backend into a bottleneck.
Reliable API integrations, webhooks, retries, idempotency, and failure handling for systems that depend on external providers.
Tenant isolation, database strategies, onboarding, permissions, and architecture for SaaS products that need clean boundaries as they grow.
For existing Laravel and backend systems that have become difficult to maintain, scale, or trust in production. I help diagnose architecture, queues, performance, integrations, and failure points before deciding what actually needs to change.
Subscription lifecycles, recurring billing, quotas, usage-based models, payment-provider integrations, and the backend rules around them.
When a project needs more than backend work, I can carry the architecture through frontend and Flutter delivery while keeping one technical owner across the system.
Client names are withheld. The architecture and the shape of the problem are not.
I do my deepest work in the parts of a product users rarely see but always depend on: APIs, integrations, queues, data boundaries, billing rules, and the architecture behind them.
My approach is backend-first because that's where reliability and system boundaries are usually decided — what happens when a provider times out, a webhook arrives twice, a queue retries a job, or one tenant must never see another tenant's data. When a project needs end-to-end delivery, I can carry that ownership into frontend and Flutter rather than handing the architecture off at the API boundary.
The goal is not complexity for its own sake. It is a system the business and engineering team can continue to operate, understand, and extend.
Retries, observability, failure handling, and rollback plans are part of the system design — not work left for after launch.
Business constraints, current architecture, failure history, and what the problem is costing the product or team.
Audit the existing system or design the architecture, document trade-offs, and decide what actually needs to change.
Implement incrementally, keeping changes understandable, testable, and safe to ship.
Validate failure paths, observability, queues, integrations, and production behavior before calling the work complete.
Continue with retained backend ownership when needed, or leave the team with a system and handover they can confidently maintain.
Where the dedupe boundary belongs when a provider retries and the customer doesn't care why.
Row scoping, schema-per-tenant, database-per-tenant — and the migration cost of each.
Poison jobs, unbounded payloads, and the retry storm that took down the database.
Tell me what you're building — or what's breaking. I'll review the problem and get back to you within two working days.
