About

Backend architecture for business-critical workflows.

I'm a backend and systems engineer with 15+ years of experience building SaaS platforms, payment systems, integrations, distributed systems, APIs, and production infrastructure.

My strongest work is at the intersection of backend architecture, reliability, business-critical workflows, and complex integrations.

Earlier in my career, I co-founded a software company that was later acquired. That experience gave me exposure not only to engineering, but also to product, operations, customers, and company-building.

Today I continue to work hands-on with software architecture and product development, including consulting and selected product work.

Where architecture, integrations, and reliability meet.

FoundationReady early-stage B2B SaaS

EventAgent

Ready early-stage event execution platform for professional event operators, with initial organizer onboarding and conversations underway.

Designed and built multi-tenant architecture, role-based authorization, event-driven workflows, approval-gated state changes, APIs, auditability, integrations, and production-oriented backend design across organizers, vendors, venues, guests, contracts, approvals, messages, timelines, and operational readiness.

Shows the kind of complex system architecture I build: clear domain boundaries, reliable workflows, and practical foundations for AI-enabled operational support.

Platform modernization and reliability

Historical work on a multi-tenant commerce platform with complex integrations, long-lived data models, and operational constraints.

Led backend architecture, data-integrity work, service-boundary improvements, performance analysis, and post-acquisition platform stabilization.

Balanced feature delivery with incremental modernization and reliability improvements across a mature production platform.

IntegrationBusiness-critical integrations

Payments, accounting, and ecommerce integrations

Integration-heavy platform work connecting payment, ecommerce, accounting, and inventory systems through explicit data and ownership boundaries.

Built and refined APIs, asynchronous workflows, idempotent processing patterns, and operational services for high-value transactions and downstream reporting.

Strengthened data-flow reliability and made integration behavior easier to operate and evolve.

DeliveryProduction operations

Cloud delivery and observability

Production platforms that required repeatable deployment, useful operational visibility, and maintainable cloud infrastructure.

Improved CI/CD, monitoring, deployment workflows, and operational hardening across Azure-led cloud infrastructure, with additional AWS, GCP, Terraform, and containerized service experience.

Made releases and production behavior easier for engineering teams to reason about and maintain.
