Backend Systems for SaaS Workflows

I have worked on backend services and integrations supporting SaaS workflows, including APIs, GraphQL services, data access layers, external service communication, and business-critical platform operations.

My work has involved TypeScript, Node.js, Python, PostgreSQL, MongoDB, ClickHouse, Redis, RabbitMQ, GraphQL, and related backend tooling.

What this involved

  • Designing and implementing backend services for product workflows and integrations.
  • Working with relational and analytical databases to support product and reporting needs.
  • Implementing retry, timeout, queueing, rate-limiting, and fault-tolerance patterns for external service communication.
  • Maintaining services that support operational and customer-facing platform behavior.

Why it mattered

Backend systems are not only technical infrastructure. They shape product reliability, user trust, operational visibility, and the ability of teams to move quickly without breaking core workflows.
