Amin Tizdastazar

Staff Backend Engineer · Toronto

Production backend systems with clear system-of-record boundaries.

I build and modernize backend systems across multi-tenant architecture, integrations, payments, inventory, accounting workflows, system-of-record design, and reliability-critical operations.

I optimize for reliability, clear architecture boundaries, auditability, and delivery that stays sustainable as systems scale toward AI-assisted workflows.

FoundationEarly-stage SaaS

EventAgent

Production-ready event coordination SaaS (EventAgent) in pilot with real users and multi-stakeholder event workflows.

Designed backend architecture, domain models, REST APIs, vendor lifecycle workflows, messaging, approvals, audit-aware operations, and system-of-record execution paths. Full stack delivery with React, Next.js, Node.js, TypeScript, PostgreSQL on Azure.

Created a pragmatic foundation that can evolve from a clear monolith toward service-based boundaries, AI-assisted proposals, and controlled workflow automation as usage grows.

ReliabilityMature platform

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.

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 AWS, GCP, Azure, and containerized services.

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